当我使用gridview:true时,afterInsertRow:function(ids)方法没有执行

Question

当我设置的GridView到真(GridView控件:真)在我们的jqGrid增加jqGrid的,就像方法的性能afterInsertRow,或者其他类似的方法不会被执行.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",

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

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

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

        { name: "hidden4",      index: "hidden4",      sorttype: "text",
          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,
    treeIcons: {leaf: "ui-icon-document-b"},
    treeGrid: true,
    treeGridModel: 'nested',
    ExpandColumn : 'Description',
    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.

请帮我

谢谢,DISMGMT

Answer 1

的用法意义gridview:true如下。在“gridview”模式下，大多数网格包含将被创建为字符串。确切地说，我们为每个网格行构建一个带有 HTML 标记的子字符串数组，从字符串数组中创建一个字符串join('')，然后才创建一个表示网格的 DOM 对象。它提高了性能，不仅因为可以更好地处理长字符串（join('')），还因为减少了对 DOM 对象的处理，因为 DOM 对象比处理字符串慢得多。

afterInsertRow所以我建议你根本不要使用。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或中loadComplete。

您将为要设置自定义工具提示的列使用自定义格式化程序来存档最佳性能。ds_name实现非常简单，因为您的自定义格式化程序将以与rowObject从服务器接收的形式相同的形式接收服务器数据行作为参数（作为数组或对象）。正确的hidden4将立即可用（我建议您阅读此答案以获取更多详细信息）。

更新：答案很旧了。jqGrid提供了许多替代的实现方式，从性能的角度来看这些方式要好得多。页面上的每次更改都会遵循浏览器重排。setCell所以in循环的使用效果并不好。更好的是使用cellattrorrowattr和 继续使用答案gridview: true中描述的优点。

答案演示了使用而不是在当前答案中使用来设置title单元格的非常有效的方法。另一个答案提供了一个更常见的示例。要设置网格行的属性，可以使用回调。请参阅代码示例的答案。cellattrsetCellcellattrrowattr
