Plupload - 添加在IE8中不起作用的文件

Question

我无法获取plupload添加文件以打开IE8中的文件选择对话框。它在Firefox中运行良好。

我尝试了一些我遇到过的不同想法：

1. 更改Z-index
2. Flash和Html4作为运行时
3. 手动触发按钮
4. 刷新上传者
5. 确保我的容器div没有隐藏

这是我的代码：

var uploader = new plupload.Uploader({
        runtimes: 'html5,html4',
        multipart: true,
        source: 'AccountDocument',
        browse_button: 'pickfiles',

        container: 'container', // ... or DOM Element itself
        url: "Home/UploadAttachment",

        filters: {
            max_file_size: '10mb',
        },

        flash_swf_url: 'http://rawgithub.com/moxiecode/moxie/master/bin/flash/Moxie.cdn.swf',
        silverlight_xap_url: 'http://rawgithub.com/moxiecode/moxie/master/bin/silverlight/Moxie.cdn.xap',

        preinit: attachCallbacks,


        init: {
            PostInit: function () {

                $('#filelist').innerHTML = '';

                $('#uploadfiles').onclick = function () {
                    $('#uploadfiles').text('Uploading...');

                   submit(false, 'AccountDocument', 'frmAccountDocument' + r, BusinessUnitID);
                    setTimeout(function () {
                        uploader.settings.multipart_params = { accountDocumentID: $("#ID").val(), description: $("#AttachmentDescription").val() };
                        uploader.start();
                        $('#uploadfiles').text('UPLOAD');

                   }, 500); 
                    return false;
                };
            },


            Browse: function (up) {
                alert('hi');
                // Called when file picker is clicked
                log('[Browse]');
            },

            FilesAdded: function (up, files) {
                $('#tblAttachmentDisplay').show();
                $('#uploadfile').show();
                $('#pickfiles').hide();


                plupload.each(files, function (file) {
                    $('#tblAttachmentDisplay #trUploadRow').show();
                    $('#tblAttachmentDisplay #trUploadRow #tdUploadFileName').text(file.name);
                    $('#tblAttachmentDisplay #trUploadRow #tdUploadDescription').html('<input type="text" class="text-box" value ="Please enter a description" id="AttachmentDescription" />');
                    $("#tblAttachmentDisplay #trUploadRow #tdUploadDescription #AttachmentDescription").focus().select();

                });
            },

            Error: function (up, err) {
                $('#console').innerHTML += "\nError #" + err.code + ": " + err.message;
            }
        }
    });




    uploader.bind("Init", function (up, params) {
        $("#runtime").html("<div>Current runtime: " + params.runtime + "</div>");
    });

    uploader.init();

    uploader.refresh();

<table id="tblAttachment">

    <tr>
        <td></td>
        <td>
            <div id="filelist"></div>
            <a id="pickfiles" href="#" class="lnkHotLightBlue txtBoldSubHeader" style="color:#5191CD;display:block;position: relative; z-index: 999999">Upload a File</a>
            <div id="container"></div>
        </td>
    </tr>

</table>
