我正在尝试使用一个ajax调用发送多个文件。 问题是我不能让我的进展工作得到这条线
TypeError: data.context is undefined
data.context.find('input').val(progress).change();
无法弄清楚如何使用sendAPI管理每个tpl的进度＆gt;？我搜索了很多尝试不同的东西，这样做的基本原因是我想要一个ajax请求并在该请求完成后控制。
MYHTML
<form id="upload" method="post" action="upload.php" enctype="multipart/form-data">
<div>
<div id="drop">
Drop Here <span style="color:white;text-transform:none;font-size: 13px"> OR <span>
<a>Browse</a>
<input type="file" name="upl[]" multiple/>
</div>
<ul>
<!-- The file uploads will be shown here -->
</ul>
</div>
</form>
MY JQUERY
// Initialize the jQuery File Upload plugin
$('#upload').fileupload({
disableImageResize: /Android(?!.*Chrome)|Opera/
.test(window.navigator && navigator.userAgent),
imageMaxWidth: 100,
imageMaxHeight: 100,

add: function(e, data) {
var type = data.files[0].type;
var size = data.files[0].size;
if ( type == 'image/jpeg' || type == 'image/png' || type == 'image/gif' ) {
if(size<=350000000)
{
// var preview = '<img src="' + URL.createObjectURL(data.files[0]) + '"/>';
var tpl = $('<li class="working"><input type="text" value="0" data-width="48" data-height="48"' +

tpl.find('p').text(data.files[0].name).append('<i>' + formatFileSize(data.files[0].size) + '</i>');
loadImage(data.files[0],
function(img) {
tpl.find('.preview').html(img);
},

progress: function(e, data) {
// Calculate the completion percentage of the upload
var progress = parseInt(data.loaded / data.total * 100, 10);
// Update the hidden input field and trigger a change

$(document).on('click','#post_picture',function(){

这就是我这样做的原因为什么这些天没有人回答：）
