jQuery对话框在多次关闭/打开后显示白色内容

我有以下脚本：-

//--show add server dialog
    $('body').on("click", "#addserver", function () {

        //Make it a dialog box. Note that you don't have to do this every time the button is called, so you might want to make it dialog on document ready or something.

        $("#showserveroptions").dialog({
            title: "Add Exsisting Server",
            width: 600,
            height: 300
        });

        var ajaxCall = $.ajax({
            url: '@Url.Content("~/Rack/showServers")',
            data: {
                rackid: "@Model.Rack.TMSRackID",

            },
            type: 'get',
            success: function (html) {
                $('#showserveroptions').html(html);
                $("#showserveroptions").dialog("show"); //This could also be dialog("open") depending on the version of jquery ui.
            }
        });

     });

它在我的asp.net mvc中调用以下操作方法以打开对话框：-

[CheckUserPermissions(Action = "Edit", Model = "Server")]
        [OutputCache(CacheProfile = "NoCache")]
        public PartialViewResult showServers(int rackid)//to display a view insdie the dialog box , for assigning servers to a rack 
        {
            AddServerToRack s = new AddServerToRack { rackID = rackid };
            return PartialView("_showServers", s);



        }

目前，当第一次打开对话框时，该对话框可以正常工作，但在多次关闭/打开后，我将在一段时间内完成以下内容：-

有人能给我建议吗？

检查

html

响应；查看是否为空否不为空，将进行调用，但不显示局部视图字段。我与firebug进行了检查，得到了200 ok作为响应消息。在使用部分视图呈现对话框之前，能否尝试清除对话框的html。i、 e.$（'#showserveroptions'）.html（“”）@D#u Learning我尝试添加$（'#showserveroptions'）.html（“”）；但这并没有改变任何事情，问题仍然在发生。。。
