Onchange 通过 select 打开 URL - jQuery

发布于 2024-10-19 13:25:17 字数 60 浏览 4 评论 0原文

在更改选择选项和 URL 时附加事件的最佳方式是什么?将 href 存储在 attr 中并在更改时获取它?

What would be the best way to attach an event so on change of a select option a URL. Store the href in an attr and grab it on change?

这很简单,让我们看一个工作示例:

<select id="dynamic_select">
  <option value="" selected>Pick a Website</option>
  <option value="http://www.google.com">Google</option>
  <option value="http://www.youtube.com">YouTube</option>
  <option value="https://www.gurustop.net">GuruStop.NET</option>
</select>

<script>
    $(function(){
      // bind change event to select
      $('#dynamic_select').on('change', function () {
          var url = $(this).val(); // get selected value
          if (url) { // require a URL
              window.location = url; // redirect
          }
          return false;
      });
    });
</script>

$(function() {
  // bind change event to select
  $('#dynamic_select').on('change', function() {
    var url = $(this).val(); // get selected value
    if (url) { // require a URL
      window.location = url; // redirect
    }
    return false;
  });
});
<select id="dynamic_select">
  <option value="" selected>Pick a Website</option>
  <option value="http://www.google.com">Google</option>
  <option value="http://www.youtube.com">YouTube</option>
  <option value="https://www.gurustop.net">GuruStop.NET</option>
</select>


<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"
        ></script>

备注:

  • 问题已经指定了 jQuery。所以,我将其他选择排除在外。
  • 在旧版本的 jQuery (<1.7) 中,您可能需要将 on 替换为 bind
  • 这是从 Meligy 的 Web 开发人员通讯 中的 JavaScript 技巧中提取的。

It is pretty simple, let's see a working example:

<select id="dynamic_select">
  <option value="" selected>Pick a Website</option>
  <option value="http://www.google.com">Google</option>
  <option value="http://www.youtube.com">YouTube</option>
  <option value="https://www.gurustop.net">GuruStop.NET</option>
</select>

<script>
    $(function(){
      // bind change event to select
      $('#dynamic_select').on('change', function () {
          var url = $(this).val(); // get selected value
          if (url) { // require a URL
              window.location = url; // redirect
          }
          return false;
      });
    });
</script>

$(function() {
  // bind change event to select
  $('#dynamic_select').on('change', function() {
    var url = $(this).val(); // get selected value
    if (url) { // require a URL
      window.location = url; // redirect
    }
    return false;
  });
});
<select id="dynamic_select">
  <option value="" selected>Pick a Website</option>
  <option value="http://www.google.com">Google</option>
  <option value="http://www.youtube.com">YouTube</option>
  <option value="https://www.gurustop.net">GuruStop.NET</option>
</select>


<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"
        ></script>

Remarks:

  • The question specifies jQuery already. So, I'm keeping other alternatives out of this.
  • In older versions of jQuery (< 1.7), you may want to replace on with bind.
  • This is extracted from JavaScript tips in Meligy’s Web Developers Newsletter.

我认为这是最简单的方法:

<select onchange="if (this.value) window.location.href=this.value">
    <option value="">Pick one:</option>
    <option value="/foo">Foo</option>
    <option value="/bar">Bar</option>
</select>

I think this is the simplest way:

<select onchange="if (this.value) window.location.href=this.value">
    <option value="">Pick one:</option>
    <option value="/foo">Foo</option>
    <option value="/bar">Bar</option>
</select>

抱歉,但是这里有太多编码......

我将免费为您提供最简单的一个。我早在 2005 年就发明了它,尽管 javascript 来源现在说是他们的员工想出了它 - 一年多后!

无论如何,就在这里,没有 JavaScript!

<!-- Paste this code into the BODY section of your HTML document  -->
<select size="1" name="jumpit" onchange="document.location.href=this.value"> 
<option selected value="">Make a Selection</option>
<option value="http://www.javascriptsource.com/">The JavaScript Source</option>
<option value="http://www.javascript.com">JavaScript.com</option>
<option value="http://www.webdeveloper.com/forum/forumdisplay.php?f=3">JavaScript Forums</option>
<option value="http://www.scriptsearch.com/">Script Search</option>
<option value="http://www.webreference.com/programming/javascript/diaries/">The JavaScript Diaries</option>
</select> 

只需输入您喜欢的任何 URL 或相对 URL(到服务器上的页面位置),它将始终有效。

Sorry, but there's to much coding going on here ...

I'll give the simplest one to you for free. I invented it back in 2005, although the javascript source now says it was their staff who came up with it - more than a year later!

Anyway, here it is, no javascript !!!

<!-- Paste this code into the BODY section of your HTML document  -->
<select size="1" name="jumpit" onchange="document.location.href=this.value"> 
<option selected value="">Make a Selection</option>
<option value="http://www.javascriptsource.com/">The JavaScript Source</option>
<option value="http://www.javascript.com">JavaScript.com</option>
<option value="http://www.webdeveloper.com/forum/forumdisplay.php?f=3">JavaScript Forums</option>
<option value="http://www.scriptsearch.com/">Script Search</option>
<option value="http://www.webreference.com/programming/javascript/diaries/">The JavaScript Diaries</option>
</select> 

Just type in any URL you like, or a relative URL (to the pages location on server), it will always work.

您可以使用这个简单的代码片段,使用 jQuery 从下拉菜单进行重定向。

<select id="dynamic-select">
    <option value="" selected>Pick a Website</option>
    <option value="http://www.google.com/">Google</option>
    <option value="http://www.youtube.com/">YouTube</option>
    <option value="http://www.stackoverflow.com/">Stack Overflow</option>
</select>

<script>
    $('#dynamic-select').bind('change', function () { // bind change event to select
        var url = $(this).val(); // get selected value
        if (url != '') { // require a URL
            window.location = url; // redirect
        }
        return false;
    });
</script>

You can use this simple code snippet using jQuery to redirect from a drop down menu.

<select id="dynamic-select">
    <option value="" selected>Pick a Website</option>
    <option value="http://www.google.com/">Google</option>
    <option value="http://www.youtube.com/">YouTube</option>
    <option value="http://www.stackoverflow.com/">Stack Overflow</option>
</select>

<script>
    $('#dynamic-select').bind('change', function () { // bind change event to select
        var url = $(this).val(); // get selected value
        if (url != '') { // require a URL
            window.location = url; // redirect
        }
        return false;
    });
</script>

我就是这样做的

<select id="urlSelect" onchange="window.location = jQuery('#urlSelect option:selected').val();">
 <option value="http://www.yadayadayada.com">Great Site</option>
 <option value="http://www.stackoverflow.com">Better Site</option>
</select>

Here's how i'd do it

<select id="urlSelect" onchange="window.location = jQuery('#urlSelect option:selected').val();">
 <option value="http://www.yadayadayada.com">Great Site</option>
 <option value="http://www.stackoverflow.com">Better Site</option>
</select>

超级简单的方法如下。无需创建函数。

<select onchange="window.location = this.options[this.selectedIndex].value">
    <option value="">Switch Language</option>
    <option value="{{ url('/en') }}">English</option>
    <option value="{{ url('/ps') }}">پښتو</option>
    <option value="{{ url('/fa') }}">دری</option>
</select>

Super easy way is as following. No need to create a function.

<select onchange="window.location = this.options[this.selectedIndex].value">
    <option value="">Switch Language</option>
    <option value="{{ url('/en') }}">English</option>
    <option value="{{ url('/ps') }}">پښتو</option>
    <option value="{{ url('/fa') }}">دری</option>
</select>

JS Fiddle 示例

$('#userNav').change(function() {
window.location = $(':selected',this).attr('href')
});




<select id="userNav">
<option></option>
<option href="http://google.com">Goolge</option>
<option href="http://duckduckgo.com">Go Go duck</option>
</select>

这适用于所选选项中的 href

JS Fiddle Example

$('#userNav').change(function() {
window.location = $(':selected',this).attr('href')
});




<select id="userNav">
<option></option>
<option href="http://google.com">Goolge</option>
<option href="http://duckduckgo.com">Go Go duck</option>
</select>

This works for the href in an option that is selected

坠似风落 2024-10-26 13:25:17

我相信在选择选项卡中重新定义位置的最简单方法如下:

<select onchange="location = this.value;">
     <option value="https://www.google.com/">Home</option>
     <option value="https://www.bing.com">Contact</option>
     <option value="mypets.php">Sitemap</option>
</select>

I believe the simplest way to redefine a location inside select tab is as follows:

<select onchange="location = this.value;">
     <option value="https://www.google.com/">Home</option>
     <option value="https://www.bing.com">Contact</option>
     <option value="mypets.php">Sitemap</option>
</select>
盛夏尉蓝 2024-10-26 13:25:17

另一种方式:

    <script type="text/javascript">
        function change_url(val) {
            window.location=val;
        }
    </script>            
    <select style="width:130px;" onchange="change_url(this.value);">
            <option value="http://www.url1.com">Option 1</option>
            <option value="http://www.url2.com">Option 2</option>
     </select>

Another way:

    <script type="text/javascript">
        function change_url(val) {
            window.location=val;
        }
    </script>            
    <select style="width:130px;" onchange="change_url(this.value);">
            <option value="http://www.url1.com">Option 1</option>
            <option value="http://www.url2.com">Option 2</option>
     </select>

如果你不希望 url 将其放在选项的值上,我会给你举个例子:

<select class="abc">
    <option value="0" href="hello">Hell</option>
    <option value="1" href="dello">Dell</option>
    <option value="2" href="cello">Cell</option>
</select>

    $("select").bind('change',function(){
        alert($(':selected',this).attr('href'));
    })

If you don't want the url to put it on option's value, i'll give u example :

<select class="abc">
    <option value="0" href="hello">Hell</option>
    <option value="1" href="dello">Dell</option>
    <option value="2" href="cello">Cell</option>
</select>

    $("select").bind('change',function(){
        alert($(':selected',this).attr('href'));
    })

试试这个代码,它工作完美

<script>
$(function() {

    $("#submit").hide();

    $("#page-changer select").change(function() {
        window.location = $("#page-changer select option:selected").val();
    })

});
</script>

<?php
    if (isset($_POST['nav'])) {
         header("Location: $_POST[nav]");
    }
?>
<form id="page-changer" action="" method="post">
    <select name="nav">

尝试此代码,它可以在 Firefox、Chrome、IE 上运行

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
<option value="" selected>---Select---</option>
<option value="https://www.google.com">Google</option>
<option value="https://www.google.com">Google</option>
<option value="https://www.google.com">Google</option>

我发现这是最好的方法。但不知道如何在新选项卡中打开每个网址

<!-- Paste this code into the BODY section of your HTML document  -->
<select size="1" name="jumpit" onchange="document.location.href=this.value">
