我正在使用 jQueryUI 和 jQuery BlueImp File Uploader。使用上传器,我想用 jQuery UI 创建可拖放的 UI 对象。
但是,为了做到这一点,我需要在显示的文件的前面和后面附加一个<li>
and标记。</li>
例如,在下面的脚本中,我使用上传器来显示上传的每个图像的缩略图。
如何 在每个正在显示的图像前li
添加和附加?/li
<script>

/*global window, $ */
$(function () {
'use strict';
// Change this to the location of your server-side upload handler:
var url = window.location.hostname === '' ?
'' : 'server/php/',
uploadButton = $('<button/>')
// .addClass('btn')
.prop('disabled', true)
// .text('Processing...')
.on('click', function () {
var $this = $(this),
data = $this.data();
$this
.off('click')
.text('Abort')
.on('click', function () {
$this.remove();
data.abort();
});
data.submit().always(function () {
$this.remove();
});
