我正在使用我在我的网站上实现的uploadifive（html5）jquery插件。在我添加文件后立即开始上传 - 在firefox中，但是当我在开始上传过程之前添加文件时，chrome会冻结2-4秒。我上传的文件大小约为 4-10 mb/文件。我可以做些什么来防止这种情况发生吗？任何帮助或建议将不胜感激。
代码：
$('#music_upload').uploadifive({
'auto' :true,
'queueID':'uploadqueue',
'simUploadLimit': 1,
'multi': true,
'queueSizeLimit' : 50,
'dnd': true,
'width': 80,
'height' : 23,
'fileSizeLimit' : 20000,
'buttonText' : 'Upload files',
'formData' : {'user' : $.cookie("username"),'key' : currentsession},
'uploadScript' : '<?php echo site_url('home/upload_music_handler'); ?>',
'removeCompleted' : false,
'onCancel' : function(file) {
// remove song from database
var username = $.cookie('username');
//check if song extension
if(checkFileExtension(file.name) == 'audio'){
//remove file and remove from db
$.post('<?php echo site_url('home/removesong'); ?>',
{ajax : 1, username : username, song_title : file.name},
function(data) {
},"json");
}
if(checkFileExtension(file.name) == 'image'){
//else remove from album cover art
$.post('<?php echo site_url('home/removealbumcover'); ?>',
{ajax : 1, username : username, song_title : file.name},
function(data) {
},"json");
//remove from display
}
//remove file
//remove li from song settings or album cover.
},
'onQueueComplete' : function(uploads) {
$(".album-settings-section").show();
//add sortable for queue-items
$( "#uploadqueue").sortable({
revert: true
});
$( ".uploadifive-queue-item" ).draggable({
connectToSortable: "#uploadqueue",
containment: "#uploadqueue",
handle: ".song_drag",
revert: "invalid"
});
},
'onUploadComplete' : function(file, data) {
$(file.queueItem).find('.songname').text(data);
$( ".songname" ).disableSelection();
$('.songname').bind('dblclick',
function(e){
e.preventDefault();
$(this).attr('contentEditable',true);
});
//get and set the songname
$(".public_or_private_album li a,.download_or_stream_album li a,.download_or_stream li a").click(function(e){
e.preventDefault();
$(this).parent().parent().find('.active').removeClass('active')
$(this).parent().addClass('active');
})
}
}); //end of upload
