代码如下

//附件上传

function AttachUpload(repath, uppath) {

    var submitUrl = "tools/upload_ajax.ashx?action=AttachFile&UpFilePath=" + uppath;

    //开始提交

    $("#form1").ajaxSubmit({

        beforeSubmit: function (formData, jqForm, options) {

            //隐藏上传按钮

            $("#" + uppath).parent().hide();

            //显示LOADING图片

            $("#" + uppath).parent().nextAll(".uploading").eq(0).show();       

        },

        success: function (data, textStatus) {



            if (data.msg == 1) {

                var listBox = $("#" + repath + " ul");



                var newLi = '<li>'

                + '<input name="hidFileName" type="hidden" value="0|' + data.mstitle + "|" + data.msgbox + '" />'

                + '<b class="close" title="删除" onclick="DelAttachLi(this);"></b>'

                + '<span class="title">附件：' + data.mstitle + '</span>'

                + '<a href="javascript:;" class="upfile"><input type="file" name="FileUpdate" onchange="AttachUpdate(\'hidFileName\',this);" /></a>'

                + '<span class="uploading">正在更新...</span>'

                + '</li>';

                listBox.append(newLi);



            } else {

                alert(data.msgbox);

            }

            $("#" + uppath).parent().show();

            $("#" + uppath).parent().nextAll(".uploading").eq(0).hide();

        },

        error: function (data, status, e) {

            alert("上传失败，错误信息：" + e);

            $("#" + uppath).parent().show();

            $("#" + uppath).parent().nextAll(".uploading").eq(0).hide();

        },

        url: submitUrl,

        type: "post",

        dataType: "json",

        timeout: 600000

    });

};
