首先它是一个容器:

<div class="upload_file_container">
    Select file!
    <input type="file" name="photo" />
</div>

第二,它是一个CSS样式,如果你想要真正更多的定制,只要保持你的眼睛是开放的:)

.upload_file_container{
   width:100px;
   height:40px;
   position:relative;
   background(your img);
}

.upload_file_container input{
   width:100px;
   height:40px;
   position:absolute;
   left:0;
   top:0;
   cursor:pointer;
}

这个例子没有按钮内文本的样式,它取决于字体大小,只需纠正容器的高度和 padding-top 值

first of all it's a container:

<div class="upload_file_container">
    Select file!
    <input type="file" name="photo" />
</div>

The second, it's a CSS style, if you want to real more customization, just keeping your eyes is open :)

.upload_file_container{
   width:100px;
   height:40px;
   position:relative;
   background(your img);
}

.upload_file_container input{
   width:100px;
   height:40px;
   position:absolute;
   left:0;
   top:0;
   cursor:pointer;
}

This example hasn't style for text inside the button, it depends on font-size, just correct the height and padding-top values for container

这是一个快速的纯 CSS 解决方法(适用于 chrome,并且包含 FireFox 后备),包括文件名、标签和自定义上传按钮,完成它应该做的事情 - 根本不需要 JavaScript!

Here is a quick pure CSS workaround (works on chrome and has a FireFox fallback included), including the file name,a label and an custom upload button, does what it should - no need for JavaScript at all! ????

Note: ☝ anyways, I would not use it on a real world website - if browser compatibility is a thing to you (what it should be). So it's more kind of experimental, otherwise while time goes by, it could be that this isn't an issue today.

要显示所选文件的路径,您可以尝试这个
在 html 上:

<div class="fileinputs">
    <input type="file" class="file">
</div>

在 javascript 中:

        var fakeFileUpload = document.createElement('div');
        fakeFileUpload.className = 'fakefile';
        var image = document.createElement('div');
        image.className='fakebtn';
        image.innerHTML = 'browse';
        fakeFileUpload.appendChild(image);
        fakeFileUpload.appendChild(document.createElement('input'));
        var x = document.getElementsByTagName('input');
        for (var i=0;i<x.length;i++) {
            if (x[i].type != 'file') continue;
            if (x[i].parentNode.className != 'fileinputs') continue;
            x[i].className = 'file hidden';
            var clone = fakeFileUpload.cloneNode(true);
            x[i].parentNode.appendChild(clone);
            x[i].relatedElement = clone.getElementsByTagName('input')[0];
            x[i].onchange = x[i].onmouseout = function () {
                this.relatedElement.value = this.value;
            }
        }

和样式:

div.fileinputs {
    position: relative;
    height: 30px;
    width: 370px;
}
input.file.hidden {
    position: relative;
    text-align: right;
    -moz-opacity: 0;
    filter: alpha(opacity: 0);
    opacity: 0;
    z-index: 2;
}
div.fakefile {
    position: absolute;
    top: 0px;
    left: 0px;
    right: 0;
    width: 370px;
    padding: 0;
    margin: 0;
    z-index: 1;
    line-height: 90%;
}
div.fakefile input {
    margin-bottom: 5px;
    margin-left: 0;
    border: none;
    box-shadow: 0px 0px 2px 1px #ccc;
    padding: 4px;
    width: 241px;
    height: 20px;
}
div.fakefile .fakebtn{
    width: 150px;
    background: #eb5a41;
    z-index: 10;
    font-family: roya-bold;
    border: none;
    padding: 5px 15px;
    font-size: 18px;
    text-align: center;
    cursor: pointer;
    -webkit-transition: all 0.4s ease;
    -moz-transition: all 0.4s ease;
    -o-transition: all 0.4s ease;
    -ms-transition: all 0.4s ease;
    transition: all 0.4s ease;
    display: inline;
    margin-left: 3px;
}
div.fileinputs input[type="file"]:hover + div .fakebtn{
    background: #DA472E;
}

div.fileinputs input[type="file"] {
    opacity: 0;
    position: absolute;
    top: -6px;
    right: 0px;
    z-index: 20;
    width: 102px;
    height: 40px;
    cursor: pointer;
}

to show path of selected file you can try this
on html :

<div class="fileinputs">
    <input type="file" class="file">
</div>

and in javascript :

        var fakeFileUpload = document.createElement('div');
        fakeFileUpload.className = 'fakefile';
        var image = document.createElement('div');
        image.className='fakebtn';
        image.innerHTML = 'browse';
        fakeFileUpload.appendChild(image);
        fakeFileUpload.appendChild(document.createElement('input'));
        var x = document.getElementsByTagName('input');
        for (var i=0;i<x.length;i++) {
            if (x[i].type != 'file') continue;
            if (x[i].parentNode.className != 'fileinputs') continue;
            x[i].className = 'file hidden';
            var clone = fakeFileUpload.cloneNode(true);
            x[i].parentNode.appendChild(clone);
            x[i].relatedElement = clone.getElementsByTagName('input')[0];
            x[i].onchange = x[i].onmouseout = function () {
                this.relatedElement.value = this.value;
            }
        }

and style :

div.fileinputs {
    position: relative;
    height: 30px;
    width: 370px;
}
input.file.hidden {
    position: relative;
    text-align: right;
    -moz-opacity: 0;
    filter: alpha(opacity: 0);
    opacity: 0;
    z-index: 2;
}
div.fakefile {
    position: absolute;
    top: 0px;
    left: 0px;
    right: 0;
    width: 370px;
    padding: 0;
    margin: 0;
    z-index: 1;
    line-height: 90%;
}
div.fakefile input {
    margin-bottom: 5px;
    margin-left: 0;
    border: none;
    box-shadow: 0px 0px 2px 1px #ccc;
    padding: 4px;
    width: 241px;
    height: 20px;
}
div.fakefile .fakebtn{
    width: 150px;
    background: #eb5a41;
    z-index: 10;
    font-family: roya-bold;
    border: none;
    padding: 5px 15px;
    font-size: 18px;
    text-align: center;
    cursor: pointer;
    -webkit-transition: all 0.4s ease;
    -moz-transition: all 0.4s ease;
    -o-transition: all 0.4s ease;
    -ms-transition: all 0.4s ease;
    transition: all 0.4s ease;
    display: inline;
    margin-left: 3px;
}
div.fileinputs input[type="file"]:hover + div .fakebtn{
    background: #DA472E;
}

div.fileinputs input[type="file"] {
    opacity: 0;
    position: absolute;
    top: -6px;

    z-index: 20;

如果您只使用 、隐藏 并自定义标签,那就更好了。

HTML:

<input type="file" id="input">
<label for="input" id="label">Choose File</label>

CSS:

input#input{
    display: none;
}
label#label{
    /* Customize your label here */
}

It's much better if you just use a <label>, hide the <input>, and customize the label.

HTML:

<input type="file" id="input">
<label for="input" id="label">Choose File</label>

CSS:

input#input{
    display: none;
}
label#label{
    /* Customize your label here */
}

这是我喜欢的一种方法,因为它使输入填充整个容器。诀窍是“font-size:100px”,它需要与“overflow:hidden”和相对位置一起使用。

<div id="upload-file-container" >
   <input type="file" />
</div>

#upload-file-container {
   width: 200px;
   height: 50px;
   position: relative;
   border: dashed 1px black;
   overflow: hidden;
}

#upload-file-container input[type="file"]
{
   margin: 0;
   opacity: 0;   
   font-size: 100px;
}

Here is one way which I like because it makes the input fill out the whole container. The trick is the "font-size: 100px", and it need to go with the "overflow: hidden" and the relative position.

<div id="upload-file-container" >
   <input type="file" />
</div>

#upload-file-container {
   width: 200px;
   height: 50px;
   position: relative;
   border: dashed 1px black;
   overflow: hidden;
}

#upload-file-container input[type="file"]
{
   margin: 0;
   opacity: 0;   
   font-size: 100px;
}

我选择了这个选项,它阐明了如何通过包含上传文件名的处理程序(也是自定义的)来完全自定义浏览按钮。
它添加了额外的字段和客户端控件,只是为了展示如何以“真实”形式(而不仅仅是独立形式)包含浏览。

这是代码笔: http://codepen.io/emiemi/pen/zxNXWR

JS:

//click on our custom btn triggers a click on the hidden actual file input 
$("#btnup").click(function(){
   $("#fileup").click();    
});


//changes on the three fields (input, tit,and name) trigger a control which checks if the 3 fields are all filled and if file field is valid (an image is uploaded)
$('#fileup').change(function(){
    var formDOMObj = document.upload;
//here we assign tu our text field #fileup the name of the selected file  
    var res=$('#fileup').val();
    var arr = res.split("\\");
//if file is not valid we show the error icon and the red alert
    if (formDOMObj.fileup.value.indexOf(".jpg") == -1 && formDOMObj.fileup.value.indexOf(".png") == -1 &&  formDOMObj.fileup.value.indexOf(".jpeg") == -1 && formDOMObj.fileup.value.indexOf(".bmp") == -1 && formDOMObj.fileup.value.indexOf(".JPG") == -1 && formDOMObj.fileup.value.indexOf(".PNG") == -1 &&  formDOMObj.fileup.value.indexOf(".JPEG") == -1 && formDOMObj.fileup.value.indexOf(".BMP") == -1){
        $( ".imgupload" ).hide("slow"); 
        $( ".imguploadok" ).hide("slow");   
        $( ".imguploadstop" ).show("slow");
        $('#nomefile').css({"color":"red","font-weight":700});
        $('#nomefile').html("The file "+arr.slice(-1)[0]+" is not an image!");
        $( "#bottone" ).hide();
        $( "#fakebtn" ).show();
    }else{
 //if file is valid we show the green alert
    $( ".imgupload" ).hide("slow");
    $( ".imguploadstop" ).hide("slow");
    $( ".imguploadok" ).show("slow");
    $('#nomefile').html(arr.slice(-1)[0]);
    $('#nomefile').css({"color":"green","font-weight":700});
    if (formDOMObj.nome.value!=""&&formDOMObj.tit.value!=""&&formDOMObj.fileup.value!=""){
  //if all three fields are valid the fake input btn is hidden and the actual one i s finally hown
        $( "#fakebtn" ).hide();
        $( "#bottone" ).show();
    }
    }
});


$('#nome').change(function(){
//same as file change but on name field
    var formDOMObj = document.upload;
    if (formDOMObj.nome.value!=""&&formDOMObj.tit.value!=""&&formDOMObj.fileup.value!=""){
        $( "#fakebtn" ).hide();
        $( "#bottone" ).show();

        $( "#bottone" ).hide();
        $( "#fakebtn" ).show();

    var formDOMObj = document.upload;
    if (formDOMObj.nome.value!=""&&formDOMObj.tit.value!=""&&formDOMObj.fileup.value!=""){
        $( "#fakebtn" ).hide();
        $( "#bottone" ).show();
    }else{
        $( "#bottone" ).hide();
        $( "#fakebtn" ).show();
    }
});

I went for this option which clarifies how to fully customize the browse button by including an handler of the uploaded file name, also customized.
It adds additional fields and client-side controls on them just to show how to include the browse in a "real" form, not just a standalone.

Here's the codepen: http://codepen.io/emiemi/pen/zxNXWR

JS:

//click on our custom btn triggers a click on the hidden actual file input 
$("#btnup").click(function(){
   $("#fileup").click();    
});


//changes on the three fields (input, tit,and name) trigger a control which checks if the 3 fields are all filled and if file field is valid (an image is uploaded)
$('#fileup').change(function(){
    var formDOMObj = document.upload;
//here we assign tu our text field #fileup the name of the selected file  
    var res=$('#fileup').val();
    var arr = res.split("\\");
//if file is not valid we show the error icon and the red alert
    if (formDOMObj.fileup.value.indexOf(".jpg") == -1 && formDOMObj.fileup.value.indexOf(".png") == -1 &&  formDOMObj.fileup.value.indexOf(".jpeg") == -1 && formDOMObj.fileup.value.indexOf(".bmp") == -1 && formDOMObj.fileup.value.indexOf(".JPG") == -1 && formDOMObj.fileup.value.indexOf(".PNG") == -1 &&  formDOMObj.fileup.value.indexOf(".JPEG") == -1 && formDOMObj.fileup.value.indexOf(".BMP") == -1){
        $( ".imgupload" ).hide("slow"); 
        $( ".imguploadok" ).hide("slow");   
        $( ".imguploadstop" ).show("slow");
        $('#nomefile').css({"color":"red","font-weight":700});
        $('#nomefile').html("The file "+arr.slice(-1)[0]+" is not an image!");

您可以设置它们的样式,但无法删除已经存在的元素。如果您有创意,您可以使用它并执行以下操作:

input[type=file] {
    -webkit-appearance: none;
    -moz-appearance: none;
    appearance: none;
    background: #EEE;
    background: linear-gradient(to top, #FFF, #DDD);
    border: thin solid rgba(0,0,0, .5);
    border-radius: .25em;
    box-shadow: inset .25em .25em .25em rgba(255,255,255, .5), inset -.1em -.1em .1em rgba(0,0,0, 0.1);
    cursor: text;
    padding: .25em;
}

http://jsfiddle.net/zr1x1m2b /1/

我建议你尝试一下这段代码,删除行,添加你自己的代码,做任何事情,直到你得到你喜欢的东西!

You can style them, but you can't remove the elements that are already there. If you're creative, you can work with that and do something like this:

input[type=file] {
    -webkit-appearance: none;
    -moz-appearance: none;
    appearance: none;
    background: #EEE;
    background: linear-gradient(to top, #FFF, #DDD);
    border: thin solid rgba(0,0,0, .5);
    border-radius: .25em;
    box-shadow: inset .25em .25em .25em rgba(255,255,255, .5), inset -.1em -.1em .1em rgba(0,0,0, 0.1);
    cursor: text;
    padding: .25em;
}

http://jsfiddle.net/zr1x1m2b/1/

I suggest you play around with this code, remove lines, add your own, do whatever until you get something that looks how you like!

只需使用您最喜欢的 CSS,按照您想要的方式设置普通按钮的样式即可。

然后调用一个简单的 JS 函数来创建隐藏的输入元素并将其链接到您的样式按钮。不要添加特定于浏览器的 CSS 来执行隐藏部分。

<!DOCTYPE html>
<meta charset="utf-8">

<style>
    button {
        width            : 160px;
        height           : 30px;
        font-size        : 13px;
        border           : none;
        text-align       : center;
        background-color : #444;
        color            : #6f0;
    }
    button:active {
        background-color : #779;
    }
</style>

<button id="upload">Styled upload button!</button>

<script>

function Upload_On_Click(id, handler) {
    var hidden_input = null;
    document.getElementById(id).onclick = function() {hidden_input.click();}
    function setup_hidden_input() {
        hidden_input && hidden_input.parentNode.removeChild(hidden_input);
        hidden_input = document.createElement("input");
        hidden_input.setAttribute("type", "file");
        hidden_input.style.visibility = "hidden";
        document.querySelector("body").appendChild(hidden_input);
        hidden_input.onchange = function() {
            handler(hidden_input.files[0]);
            setup_hidden_input();
        };
    }
    setup_hidden_input();
}

Upload_On_Click("upload", function(file) {
    console.log("GOT FILE: " + file.name);
});

</script>

请注意每次用户选择文件后上述代码如何重新链接它。这很重要,因为只有当用户更改文件名时才会调用“onchange”。但您可能希望在每次用户提供文件时获取该文件。

有关更多详细信息,请研究 DropZone 和 Gmail 上传。

Just style a normal button however you want, using your favorite CSS.

Then call a simple JS function to create and link a hidden input element to your styled button. Don't add browser-specific CSS to do the hiding part.

<!DOCTYPE html>
<meta charset="utf-8">

<style>
    button {
        width            : 160px;
        height           : 30px;
        font-size        : 13px;
        border           : none;
        text-align       : center;
        background-color : #444;
        color            : #6f0;
    }
    button:active {
        background-color : #779;
    }
</style>

<button id="upload">Styled upload button!</button>

<script>

function Upload_On_Click(id, handler) {
    var hidden_input = null;
    document.getElementById(id).onclick = function() {hidden_input.click();}
    function setup_hidden_input() {
        hidden_input && hidden_input.parentNode.removeChild(hidden_input);
        hidden_input = document.createElement("input");
        hidden_input.setAttribute("type", "file");
        hidden_input.style.visibility = "hidden";
        document.querySelector("body").appendChild(hidden_input);
        hidden_input.onchange = function() {
            handler(hidden_input.files[0]);
            setup_hidden_input();
        };
    }
    setup_hidden_input();
}

Upload_On_Click("upload", function(file) {
    console.log("GOT FILE: " + file.name);
});

</script>

Notice how the above code re-links it after every time the user chooses a file. This is important because "onchange" is only called if the user changes the filename. But you probably want to get the file every time the user provides it.

For more details, research DropZone and gmail uploads.

这是我最近发现的一种方法,使用了一些 jQuery

HTML 代码:

<form action="">
    <input type="file" name="file_upload" style="display:none" id="myFile">

    <a onclick="fileUpload()"> Upload a file </a>
</form>

对于 javascript/jQuery 部分:

<script>
function fileUpload() {
    $("#myFile").click();
}
</script>

在这个示例中,我放置了一个“锚”标签来触发文件上传。您可以替换为任何您想要的内容,只需记住将“onclick”属性设置为正确的功能即可。

希望这有帮助!

PS:不要忘记包含来自 CDN 或任何其他来源的 jQuery

Here is one way I recently discovered, with a bit of jQuery

HTML Code:

<form action="">
    <input type="file" name="file_upload" style="display:none" id="myFile">

    <a onclick="fileUpload()"> Upload a file </a>
</form>

For the javascript/jQuery part :

<script>
function fileUpload() {
    $("#myFile").click();
}
</script>

In this example, I have put an "anchor" tag to trigger the file upload. You can replace with anything you want, just remember to put the "onclick" attribute with the proper function.

Hope this helps!

P.S. : Do not forget to include jQuery from CDN or any other source

您无法对 input[type=file] 控件本身进行太多修改。

由于单击与输入正确配对的 label 元素将激活/聚焦它,因此我们可以使用 label 来触发操作系统浏览对话框。

您可以这样做……

label {
   cursor: pointer;
   /* Style as you please, it will become the visible UI component. */
}

#upload-photo {
   opacity: 0;
   position: absolute;
   z-index: -1;
}
<label for="upload-photo">Browse...</label>
<input type="file" name="photo" id="upload-photo" />

表单控件的 CSS 将使其显示为不可见,并且不会占用文档布局中的空间,但仍然存在,因此可以通过标签激活它。

如果您想在选择后显示用户选择的路径,您可以使用 JavaScript 侦听 change 事件,然后读取浏览器为您提供的路径(出于安全原因,它可能会欺骗您) 告诉你确切的路径)。让最终用户满意的一种方法是简单地使用返回的路径的基本名称(这样用户只需看到所选的文件名)。

有一个 Tympanus 的精彩指南 用于设计这个。

You can’t modify much about the input[type=file] control itself.

Since clicking a label element correctly paired with an input will activate/focus it, we can use a label to trigger the OS browse dialog.

Here is how you can do it…

label {
   cursor: pointer;
   /* Style as you please, it will become the visible UI component. */
}

#upload-photo {
   opacity: 0;
   position: absolute;
   z-index: -1;
}
<label for="upload-photo">Browse...</label>
<input type="file" name="photo" id="upload-photo" />

The CSS for the form control will make it appear invisible and not take up space in the document layout, but will still exist so it can be activated via the label.

If you want to display the user’s chosen path after selection, you can listen for the change event with JavaScript and then read the path that the browser makes available to you (for security reasons it can lie to you about the exact path). A way to make it pretty for the end user is to simply use the base name of the path that is returned (so the user simply sees the chosen filename).

There is a great guide by Tympanus for styling this.

也许是这样的?

<form>
  <input id="fileinput" type="file" style="display:none;"/>
</form>
<button id="falseinput">El Cucaratcha, for example</button>
<span id="selected_filename">No file selected</span>

<script>
$(document).ready( function() {
  $('#falseinput').click(function(){
    $("#fileinput").click();
  });
});
$('#fileinput').change(function() {
  $('#selected_filename').text($('#fileinput')[0].files[0].name);
});

</script>

Something like that maybe?

<form>
  <input id="fileinput" type="file" style="display:none;"/>
</form>
<button id="falseinput">El Cucaratcha, for example</button>
<span id="selected_filename">No file selected</span>

<script>
$(document).ready( function() {
  $('#falseinput').click(function(){
    $("#fileinput").click();
  });
});
$('#fileinput').change(function() {
  $('#selected_filename').text($('#fileinput')[0].files[0].name);
});

</script>

为什么不呢? ^_^

请参阅此处的示例

  <label for="fusk">dsfdsfsd</label>
  <input id="fusk" type="file" name="photo" style="display: none;">

why not? ^_^

诀窍是隐藏输入并自定义标签。

输入图像描述这里

HTML:

<div class="inputfile-box">
  <input type="file" id="file" class="inputfile" onchange='uploadFile(this)'>
  <label for="file">
    <span id="file-name" class="file-box"></span>
    <span class="file-button">
      <i class="fa fa-upload" aria-hidden="true"></i>
      Select File
    </span>
  </label>
</div>

CSS:

.inputfile-box {
  position: relative;
}

.inputfile {
  display: none;
}

.container {
  display: inline-block;
  width: 100%;
}

.file-box {
  display: inline-block;
  width: 100%;
  border: 1px solid;
  padding: 5px 0px 5px 5px;
  box-sizing: border-box;
  height: calc(2rem - 2px);
}

.file-button {
  background: red;
  padding: 5px;
  position: absolute;
  border: 1px solid;
  top: 0px;
  right: 0px;
}

JS:

function uploadFile(target) {
    document.getElementById("file-name").innerHTML = target.files[0].name;
}

The trick is hide the input and customize the label.

enter image description here

HTML:

<div class="inputfile-box">
  <input type="file" id="file" class="inputfile" onchange='uploadFile(this)'>
  <label for="file">
    <span id="file-name" class="file-box"></span>
    <span class="file-button">
      <i class="fa fa-upload" aria-hidden="true"></i>
      Select File
    </span>
  </label>
</div>

CSS:

.inputfile-box {
  position: relative;
}

.inputfile {
  display: none;
}

.container {
  display: inline-block;
  width: 100%;
}

.file-box {
  display: inline-block;
  width: 100%;
  border: 1px solid;
  padding: 5px 0px 5px 5px;
  box-sizing: border-box;
  height: calc(2rem - 2px);
}

.file-button {
  background: red;
  padding: 5px;
  position: absolute;
  border: 1px solid;
  top: 0px;
  right: 0px;
}

JS:

function uploadFile(target) {
    document.getElementById("file-name").innerHTML = target.files[0].name;
}
