uploadify加ASP.NET MVC3.0上传文件（可多条）

页面代码：

<div id="fileQueuePlug"></div>
            <input type="file" name="uploadifyplug" id="uploadifyplug" />
            <a href="javascript:$('#uploadifyplug').uploadifyUpload();">上传</a>

<input id="windowspathplug" type="hidden" value="" />

脚本加载ckeditor插件并提交：

$(function () {
    $("#uploadifyplug").uploadify({
        'uploader': '/Scripts/uploadify/uploadify.swf',
        'script': '/ToolsAndPlug/UploadImage',
        'cancelImg': '/Scripts/uploadify/uploadify-cancel.png',
        'folder': '/Image/Uploads/ToolsOrPlug',
        'queueID': 'fileQueuePlug',
        'auto': false,
        'multi': false,///设置true可实现多条上传
        'fileExt': '*.jpg;*.png;*.jpeg;*.gif;*.bmp',
        'fileDesc': '请选择图片类型文件',
        'sizeLimit': 1024 * 1024 * 10,
        'onSelect': function (e, queueId, fileObj) {
            $("#uploadifyplug").uploadifySettings('scriptData', { 'windowspathjs': $("#windowspathplug").val() });
        },
        'onComplete': fun
    });
});
function fun(event, queueId, fileObj, response, data) {
    if (response != "") {
        $.messager.show({
            title: '提示',
            msg: '上传成功',
            timeout: 5000,
            showType: 'slide'
        });
        var displaypath;
        var windowspath;
        var arr = new Array();
        arr = response.split("|");
        displaypath = arr[0];
        windowspath = arr[1];
        $("#plugortoolsimage").attr("value", displaypath);
        $("#windowspathplug").attr("value", windowspath);
    }
    else {
        $.messager.show({
            title: '提示',
            msg: '上传失败',
            timeout: 5000,
            showType: 'slide'
        });
    }
}
