我正在使用 Jquery ajax。

我进行了 ajax 调用以获取数据并连接 html 字符串并附加到 div 的 id。

$("#divMenuList").html(JsMenuListHtml);

alert($("#divMenuList").html());

但是警报显示未定义。如果我是页面更改它第一次使用 html 字符串显示，但如果我将删除第二页记录并重新调用该函数，它将显示未定义，我有它使用列表。

这是整个功能：

function performlisting(data, JsCurrPage) {
    var JsMenuTitle = '';
    var JsOrderNumber = '';    
    var JsMenuId = '';    
    var JsMenuListHtml = '';    
    var JsCounter = 0;    
    var JsAlternateRow = '';    
    var JsIsActive = "false";    
    var JsIsActiveClass = "";    
    var JsIsActiveTitle = "";


    if (data.Data.length > 0) {
        for (i = 0; i < data.Data.length ; i++) {
            JsCounter++;

            if (JsCounter % 2 == 0) {
                JsAlternateRow = "alternate-row";
            }
            else {
                JsAlternateRow = '';
            }

            //set true/false for update status
            if (data.Data[i]['IsActive'] == true) {
                JsIsActive = "false";
                JsIsActiveClass = "icon-3 info-tooltip";
                JsIsActiveTitle = "Published";
            }
            else if (data.Data[i]['IsActive'] == false) {
                JsIsActive = "true";
                JsIsActiveClass = "icon-4 info-tooltip";
                JsIsActiveTitle = "UnPublished";
            }
            else {
                JsIsActive = "false";
                JsIsActiveClass = "icon-4 info-tooltip";
                JsIsActiveTitle = "UnPublished";
            }

            JsMenuTitle = data.Data[i]['MenuTitle'];
            JsOrderNumber = data.Data[i]['OrderNumber'];
            JsMenuId = data.Data[i]['MenuId'];

            JsMenuListHtml = JsMenuListHtml +
                '<tr class= ' + JsAlternateRow + '>' +
                    '<td style="width:3.4%;"><input type="checkbox" value=' + JsMenuId + ' /></td><td  style="width:38.8%;">' + JsMenuTitle + '</td>' +
                    '<td style="width:39%;">' +
                    '<a title="Up-Rank" href="javascript:void(0);" onclick="return performUpMenu(\'' + JsOrderNumber + '\', \'' + JsMenuId + '\')"><img  src=' + JsUpImage + '></a>' +
                    '<a title="Down-Rank"  href="javascript:void(0);" onclick="return performDownMenu(\'' + JsOrderNumber + '\', \'' + JsMenuId + '\')"><img  src=' + JsDownImage + '></a>' +
                    '' + JsOrderNumber + '</td>' +

                    '<td class="options-width"><a href="/Admin/Menu/AddEdit/' + JsMenuId + '/'+JsCurrPage+'" title="Edit Menu" class="icon-1 info-tooltip"></a>' +
                    '<a href="javascript:void(0);" onclick="return performdeletemenu(\'' + JsMenuId + '\');" title="Delete Menu" class="icon-2 info-tooltip"></a>' +
                    '<a href="javascript:void(0);"   onclick="return performstatusmenu(\'' + JsIsActive + '\', \'' + JsMenuId + '\');" title= ' + JsIsActiveTitle + ' class=' + JsIsActiveClass + '></a>' +
                    '</td>' +
                '</tr>';
        }

        $("#divMenuList").html("");
        $("#divMenuList").html(JsMenuListHtml);

        alert($("#divMenuList").html());
        //hide num of raws dropdown
        if (parseInt(JsTotalRecs) > parseInt(JsPageSize)) {
            alert("Called1");
            SetPaging(JsTotalRecs, parseInt(JsCurrPage));
        }
        else {
            alert("Called");
            $("#pager").html('');             
        }

        $("#CurrPage").val(JsCurrPage);
        SetAllCheckboxes();
    }
    else {            
        if ($("#CurrPage").val() > 1) {
            //Error Message Pager
            $("#product-table").html("");
            $("#divSuccessMessage").html("");
            alert(parseInt($("#CurrPage").val()));
            GetListing(parseInt($("#CurrPage").val() - 1), parseInt(JsPageSize));
        }
        else {
            $("#product-table").html("");
            $("#divErrMessage").html("");
            $("#divSuccessMessage").html("");
        }            
    }
}
