当我在jqGrid中将 gridview 设置为 true （gridview：true）以提高jqGrid的性能时，像 afterInsertRow 这样的方法，或者不执行其他类似的方法。 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',

"Sales $", "Profit $", "GP%","Hidden","Hidden1","Hidden2",
"Start Date and End Date", "Hidden4"],

{ name: "hidden1", index: "hidden1", sorttype: "int",
align: "center", hidden: true },
{ name: "hidden2", index: "hidden2", sorttype: "text",
align: "center", hidden: true },
{ name: "hidden3", index: "hidden3", sorttype: "int",
align: "center", hidden: true },
{ name:"forecast_dates",index:"forecast_dates",sorttype: "text",
align: "center", hidden: true },
{ name: "hidden4", index: "hidden4", sorttype: "text",

],
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,

ExpandColClick: true,
loadonce:false,
refresh : true,
shrinkToFit: true,
gridview:true,
sortorder:"asc",
sortname:"displaylistGrid_ds_profit_promo"
});
以下是 afterInsertRow 方法的代码：
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。
请帮帮我

gridview:true的用法意义如下。在“gridview”模式中，最多网格包含将创建为字符串。准确地说，为每个网格行构建一个带有HTML标记的子字符串数组，从字符串数组创建一个字符串，相对于join('')，然后只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('')），而且因为减少了对DOM对象的处理，这对于使用字符串来说要慢得多。
所以我建议你根本不要使用afterInsertRow。而不是你可以成功地对以下代码做同样的事情
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或loadComplete。
您将使用custom formatter为要设置自定义工具提示的列ds_name存档的最佳效果。实现非常简单，因为您的自定义格式化程序将以rowObject参数的形式接收服务器数据的行，其形式与从服务器（作为数组或作为对象）接收的服务器数据相同。可以立即访问正确的hidden4（建议您阅读this answer了解更多详情。）
更新：答案很老。从性能的角度来看，jqGrid提供了许多替代实现方法，这些方法要好得多。页面上的每个更改都在浏览器reflow之后。因此，循环中setCell的使用无效。更好的是使用cellattr或rowattr并继续使用gridview: true the answer中描述了哪些优势。
The answer演示了使用title代替当前答案中使用的cellattr在单元格上设置setCell的非常有效的方法。 Another answer提供了一个使用cellattr的常见示例。要设置网格行的属性，可以使用rowattr回调。有关代码示例，请参阅the answer。

Note: this event does not fire if gridview option is set to true
我遇到了类似的问题，在阅读了jqgrid的wiki后，如果有其他人遇到同样的问题我会考虑提供文档链接。
