jquery-easyui中表格的行编辑功能

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：



代码如下：

Js代码


$('#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:{

valueField:'productid',

textField:'name',

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:{

type:'checkbox',

options:{

on: 'P',

off: ''

}

}

},

{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 {

var e = '<a href="#" onclick="editrow('+index+')">Edit</a> ';

var d = '<a href="#" onclick="deleterow('+index+')">Delete</a>';

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);

},

onCancelEdit:function(index,row){

row.editing = false;

$('#tt').datagrid('refreshRow', index);

}

});
