Upload Preview jQuery Plugin
What is that?
这个 jQuery 插件提供了一种简单的方法来在实际上传到服务器之前预览您的上传。 因此,如果您从硬盘驱动器中选择了一个图像或音频文件,它将为音频文件生成所选图像或音频播放器的实时预览。
How it works
要访问未上传的数据,我们可以使用 HTML5 文件阅读器 api。 这个api提供读取本地文件。 这一步非常重要,因为我们需要这些数据才能在浏览器窗口中显示它。 要获得有关文件阅读器的更多信息,您可以阅读官方文档。
Download
转到 assets/js/ 文件夹。
Installation
<强>1。 复制 jQuery & 插件:
<script type="text/javascript" src="http://code.jquery.com/jquery-2.0.3.min.js"></script>
<script type="text/javascript" src="assets/js/jquery.uploadPreview.min.js"></script>
2. 设置您的上传表单,例如:
<div id="image-preview">
<label for="image-upload" id="image-label">Choose File</label>
<input type="file" name="image" id="image-upload" />
</div>
3. 根据需要随时加载插件功能,并用参数填充它:
<script type="text/javascript">
$(document).ready(function() {
$.uploadPreview({
input_field: "#image-upload", // Default: .image-upload
preview_box: "#image-preview", // Default: .image-preview
label_field: "#image-label", // Default: .image-label
label_default: "Choose File", // Default: Choose File
label_selected: "Change File", // Default: Change File
no_label: false, // Default: false
success_callback: null // Default: null
});
});
</script>
Customization
您可以自由自定义输入、预览和显示的 CSS 和 HTML。 标签字段。 随意更改它。 您没有必要像在第 2 步中看到的那样将所有内容放在一起。预览框可能位于页面上的其他位置,就像输入字段一样。

Upload Preview jQuery Plugin
What is that?
This jQuery plugin provides an easy way to preview your uploads before they're actually uploaded to the server. So if you selected an image or audio file from your hard drive, it will generate a live preview of the selected image or audio player for the audio file.
How it works
To get access to the not uploaded data, we can use the HTML5 file reader api. This api provides reading local files. This step is pretty important, because we need to this data in order to show it in the browser window. To get more information about the file reader, you can read the official documentation.
Download
Go to assets/js/ folder.
Installation
1. Copy jQuery & plugin:
<script type="text/javascript" src="http://code.jquery.com/jquery-2.0.3.min.js"></script>
<script type="text/javascript" src="assets/js/jquery.uploadPreview.min.js"></script>
2. Set up your upload form e.g.:
<div id="image-preview">
<label for="image-upload" id="image-label">Choose File</label>
<input type="file" name="image" id="image-upload" />
</div>
3. Load the plugin function as often as you need and fill it with the parameters:
<script type="text/javascript">
$(document).ready(function() {
$.uploadPreview({
input_field: "#image-upload", // Default: .image-upload
preview_box: "#image-preview", // Default: .image-preview
label_field: "#image-label", // Default: .image-label
label_default: "Choose File", // Default: Choose File
label_selected: "Change File", // Default: Change File
no_label: false, // Default: false
success_callback: null // Default: null
});
});
</script>
Customization
You're free to customize the CSS and HTML for the input, preview & label fields. Feel free to change it as you wish. There's no need that you put it all together as you can see in step 2. The preview box might be located somewhere else on your page as the input field is.
