// 初始化DataGrid對象
    $('#dataGrid').dataGrid({
        searchForm: $("#searchForm"),
        showCheckbox: true,
        columnModel: [
            {header:'${text("主鍵")}', name:'id', index:'a.id', width:150, align:"center",hidden:true},
            //code作為回調(diào)頁面保存使用,value僅作為回調(diào)頁面的展示使用
            {header:'${text("拍攝類型code")}', name:'categoryShoot', index:'a.category_shoot', width:150, align:"center",hidden:true},
            {header:'${text("拍攝類型")}', name:'categoryShootName', index:'a.category_shoot', width:150, align:"center"},

            {header:'${text("分類code")}', name:'categorySuite', index:'a.category_suite', width:150, align:"center",hidden:true},
            {header:'${text("分類")}', name:'categorySuiteName', index:'a.category_suite', width:150, align:"center"},

            {header:'${text("拍攝產(chǎn)品code")}', name:'categoryProduct', index:'a.category_product', width:150, align:"center",hidden:true},
            {header:'${text("拍攝產(chǎn)品")}', name:'categoryProductName', index:'a.category_product', width:150, align:"center"},

            {header:'${text("拍攝效果code")}', name:'categoryEffect', index:'a.category_effect', width:150, align:"center",hidden:true},
            {header:'${text("拍攝效果")}', name:'categoryEffectName', index:'a.category_effect', width:150, align:"center"},

            {header:'${text("單價(件/套)")}', name:'price', index:'a.price',width:100, align:"right", formatter:'integer', formatoptions:{
                thousandsSeparator:',', defaulValue:''
            }}
        ],
        //每一行的選中事件
        onSelectRow: function (id, isSelect, event) {
            addOneGridSelect(id, isSelect);
         },
        //選擇所有行
        onSelectAll:function(rowIds, isSelect){
            addAllGridSelect(rowIds, isSelect);
        },
        //表格加載完后事件
        gridComplete:function(){
            dataGridSelection();
        },
        // 加載成功后執(zhí)行事件
        ajaxSuccess: function(data){

        }
    });

再添加以下三個方法

//表格加載完之后,根據(jù)全局?jǐn)?shù)組ids,設(shè)置需要選中的列
function dataGridSelection() {
    if (!ids) {      
        return false;    
    }    
    var dataGridRows = $('#dataGrid').jqGrid('getRowData');   
    //找到相同的id列,設(shè)置其為選中狀態(tài) 
    for (var i = 0; i < dataGridRows.length; i++) {      
        for (var j = 0; j < ids.length; j++) {        
            if (dataGridRows[i].id == ids[j]) {        
                $("#dataGrid").setSelection(dataGridRows[i].id)        
            }      
        }    
    }

}

//將選中行的ID都加到數(shù)組  ids鳖敷，
function addOneGridSelect(id, isSelect) {
    if (isSelect) {
        if (ids.indexOf(id) == -1) {      
            ids.push(id);    
        } 
    } else {
        var indexTmp = ids.indexOf(id);    
        if (indexTmp != -1) {      
            for (var i = 0; i < ids.length; i++) {        
                if (ids[i] == id) {          
                    ids.splice(i, 1);        
                }      
            }    
        }
    }  
}
   
function addAllGridSelect(rowIds, isSelect) {    
    debugger;
    if (isSelect) {    
        for (var i = 0; i < rowIds.length; i++) {      
            if (ids.indexOf(rowIds[i]) == -1) {        
                ids.push(rowIds[i]);      
            }    
        }    
    } else {    
        for (var i = 0; i < rowIds.length; i++) {      
            var indexTmp = ids.indexOf(rowIds[i]);      
            if (indexTmp != -1) {        
                for (var j = 0; j < ids.length; j++) {          
                    if (ids[j] == rowIds[i]) {            
                        ids.splice(j, 1);          
                    }        
                }      
            }    
        }    
    }  
}
