jqgrid - afterInsertRow : function(ids) method is not executing when I use gridview:true

Question

当我设置 网格 View 至 真 (gridview:true) 在我们的 jqGrid 中提高 jqGrid 的性能，方法如 afterInsertRow ，或不执行其他类似方法。
以下是我的 jgGrid 的代码:

jQuery("#displaylistGrid").jqGrid({
    url: contextRoot + '/StandardProxy/displayListService?userRole='+
         userRole+'&userName='+userName+'&userId='+userId+
         '&duration='+displayDuration+'&wicNo='+wicNo+
         '&displayName='+dlDisplayName+'&displayNameArr='+displayNameArr+
         '&pointValue='+pValue+'&locationId='+locId+'&locationCode='+
         locCode+'&serviceType=forecast',
    datatype: 'json',
    colNames: ["CM Name", "Display ", "Loc. Pt.","Max. Ben." ,"Display Name",

          align: "center",      hidden: false }
    ],
    onSelectRow: function(ids){ 
        //checkDisplayDetail();
        //setDefaultValuesToTheSortingParams();
        var dropDownVal = document.getElementById("displayDetailSelection").value;
        var subTabName = document.getElementById("detailSubTabName").value;
        if(subTabName=="Active")
            dropDownVal = document.getElementById("displayDetailActiveSelection").value;
         reLoadDisplayDetailData(ids,'forecast',dropDownVal,subTabName);
    },
    afterInsertRow : function(ids) {  // shows custom tooltip
        var customToolTip = jQuery("#displaylistGrid").getCell(ids,'ds_name') +
                     " -- " + jQuery("#displaylistGrid").getCell(ids,'hidden4');
        $("#displaylistGrid").setCell(ids,'ds_name', '','',{title:customToolTip}); 
    }, 
    gridComplete : function(){
        if($("#isForecastedSalesGridLoaded").val()=="no"){
            $("#jqgh_displaylistGrid_ds_profit_promo").click();
        }
        else{
            $("#isForecastedSalesGridLoaded").val("no");
        }
    },
    onSortCol : function(){
        $("#isForecastedSalesGridLoaded").val("yes");
    },
    width: 983,
    rowNum: 999,
    height: eval(heightOfDispListGrid()+7),
    toolbar: [true, "top"],
    viewrecords: true,

    shrinkToFit: true,
    gridview:true,         
    sortorder:"asc",
    sortname:"displaylistGrid_ds_profit_promo"
});

以下是 的代码afterInsertRow 方法:

afterInsertRow : function(ids) {  // shows custom tooltip
    var customToolTip = jQuery("#displaylistGrid").getCell(ids,'ds_name') + " -- " +
                        jQuery("#displaylistGrid").getCell(ids,'hidden4') ;
    $("#displaylistGrid").setCell(ids,'ds_name', '','',{title:customToolTip}); 
}, 

上述代码用于显示自定义工具提示。请告诉我我做错了什么。

请帮我

谢谢，

gridview:true的使用感正在跟随。在“gridview”模式下，将创建最多包含的网格 作为字符串 .为了准确地为每个网格行构建一个带有 HTML 标记的子字符串数组，一个人从关于 join('') 的字符串数组中创建一个字符串。然后才创建一个表示网格的 DOM 对象。它提高了性能，不仅因为更好地处理长字符串( join('') )，还因为减少了处理 DOM 对象的工作，这比处理字符串慢得多。

所以我建议你不要使用 afterInsertRow根本。相反，您可以成功地对以下代码执行相同的操作

var myGrid = jQuery("#displaylistGrid");
var ids = myGrid.jqGrid('getDataIDs');
for (var i = 0; i < ids.length; i++) {
    var id=ids[i];
    var customToolTip = myGrid.jqGrid('getCell',ids,'ds_name') + " -- " +
                        myGrid.jqGrid('getCell',ids,'hidden4');
    myGrid.jqGrid('setCell',ids,'ds_name', '','',{title:customToolTip});
}

您可以将其包含在 gridComplete 中或 loadComplete .

您将使用 custom formatter 存档的最佳性能为列 ds_name您想要设置自定义工具提示的位置。实现非常简单，因为您的自定义格式化程序将收到 rowObject参数以相同形式的服务器数据行，就像它将从服务器接收一样(作为数组或作为对象)。正确的 hidden4将立即访问(我建议您阅读 this answer 了解更多详细信息)。

更新 : 答案很老了。 jqGrid 提供了许多替代的实现方式，从性能的角度来看要好得多。页面上的每一个变化都跟随浏览器 reflow .所以 setCell的用法在循环中无效。更好的是使用 cellattr或 rowattr并继续使用 gridview: true the answer中描述了哪些优点.

The answer演示了设置 title 的非常有效的方法在单元格上使用 cellattr而不是 setCell在当前答案中使用。 Another answer提供一个更常见的使用示例 cellattr .要设置网格行的属性可以使用 rowattr打回来。见 the answer对于代码示例。
