具体实现代码如下：

<table id="tt"></table>
$(‘#tt‘).datagrid({
    title:‘Editable DataGrid‘,
    iconCls:‘icon-edit‘,
    width:660,
    height:250,
    singleSelect:true,
    idField:‘itemid‘,
    url:‘datagrid_data.json‘,
    columns:[[
        {field:‘itemid‘,title:‘Item ID‘,width:60},
        {field:‘productid‘,title:‘Product‘,width:100,
            formatter:function(value){
                for(var i=0; i<products.length; i++){
                    if (products[i].productid == value) return products[i].name;
                }
                return value;
            },
            editor:{

                    data:products,
                    required:true
                }
            }
        },
        {field:‘listprice‘,title:‘List Price‘,width:80,align:‘right‘,editor:{type:‘numberbox‘,options:{precision:1}}},
        {field:‘unitcost‘,title:‘Unit Cost‘,width:80,align:‘right‘,editor:‘numberbox‘},
        {field:‘attr1‘,title:‘Attribute‘,width:150,editor:‘text‘},
        {field:‘status‘,title:‘Status‘,width:50,align:‘center‘,
            editor:{

            }
        },
        {field:‘action‘,title:‘Action‘,width:70,align:‘center‘,
            formatter:function(value,row,index){
                if (row.editing){
                    var s = ‘<a href="#" onclick="saverow(‘+index+‘)">Save</a> ‘;
                    var c = ‘<a href="#" onclick="cancelrow(‘+index+‘)">Cancel</a>‘;
                    return s+c;
                } else {

                    return e+d;
                }
            }
        }
    ]],
    onBeforeEdit:function(index,row){
        row.editing = true;
        $(‘#tt‘).datagrid(‘refreshRow‘, index);
    },
    onAfterEdit:function(index,row){
        row.editing = false;
        $(‘#tt‘).datagrid(‘refreshRow‘, index);

datagrid现在具有行编辑能力了，使用时只须在columns中为需要编辑的列添加一个editor属性，编辑保存时同时具有数据校验能力。

看一个例子效果图：

具体实现代码如下：

<table id="tt"></table>
$(‘#tt‘).datagrid({
    title:‘Editable DataGrid‘,
    iconCls:‘icon-edit‘,
    width:660,
    height:250,
    singleSelect:true,
    idField:‘itemid‘,
    url:‘datagrid_data.json‘,
    columns:[[
        {field:‘itemid‘,title:‘Item ID‘,width:60},
        {field:‘productid‘,title:‘Product‘,width:100,
            formatter:function(value){
                for(var i=0; i<products.length; i++){
                    if (products[i].productid == value) return products[i].name;
                }
                return value;
            },
            editor:{
                type:‘combobox‘,
                options:{
