我的jquery

$("#upload").uploadify({

                                buttonText: ' Upload Profile Image',
    'onError' : function (a, b, c, d) {
         if (d.status == 404)
            alert('Could not find upload script.');
         else if (d.type === "HTTP")
            alert('error '+d.type+": "+d.status);
         else if (d.type ==="File Size")
            alert(c.name+' '+d.type+' Limit: Your file size is too big, our max is 100Kb');
         else

        },
    'onComplete'   : function (event, queueID, fileObj, response, data) {

        $.ajax({type: "POST",url:"/members/image_preview",data:{filearray: response},success: function(info){
            $("#target").html(info);

Answer 1

我遇到过这个问题。发生这种情况是因为Uploadify使用该行上的“设置”，如果您的html中有一个名为“settings”的id，则Uploadify会在IE中引发异常。好像FF和Safari忽略了这个问题。所以，只是不要在页面的html中保留任何名为“settings”的id，其中包含Uploadify组件，你应该很好：）

Answer 2

我刚发现的一点是，在IE中，如果在初始化swf文件时隐藏了上传区域，则uploadify onOpen（）事件永远不会触发，文件上传永远不会启动。因此，请确保上传曲目的div不是用css隐藏的，以便稍后在uploadify函数启动时显示，或者在显示资源区div之前不启动该函数。

Answer 3

您可以尝试使用未最小化版本的Jquery并发布有问题的行吗？这样，有人可能能够理解错误消息。

Answer 4

问题是，你的IE没有安装Flash版本。

因为变量 flashInstalled 是 false ，所以uploadify-script不会输入变量 swfuploadify 。

为您的浏览器安装Flash版本或使用HTML5-Version

如果您在IE中有另一个错误，例如 Object expected ，那么下面的页面应该解决它：链接
