jquery-easyui中表格的行编辑功能

http://stworthy.iteye.com/blog/689080 

 

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  

1. $('#tt').datagrid({  
2.     title:'Editable DataGrid',  
3.     iconCls:'icon-edit',  
4.     width:660,  
5.     height:250,  
6.     singleSelect:true,  
7.     idField:'itemid',  
8.     url:'datagrid_data.json',  
9.     columns:[[  
10.         {field:'itemid',title:'Item ID',width:60},  
11.         {field:'productid',title:'Product',width:100,  
12.             formatter:function(value){  
13.                 for(var i=0; i<products.length; i++){  
14.                     if (products[i].productid == value) return products[i].name;  
15.                 }  
16.                 return value;  
17.             },  
18.             editor:{  
19.                 type:'combobox',  
20.                 options:{  
21.                     valueField:'productid',  
22.                     textField:'name',  
23.                     data:products,  
24.                     required:true  
25.                 }  
26.             }  
27.         },  
28.         {field:'listprice',title:'List Price',width:80,align:'right',editor:{type:'numberbox',options:{precision:1}}},  
29.         {field:'unitcost',title:'Unit Cost',width:80,align:'right',editor:'numberbox'},  
30.         {field:'attr1',title:'Attribute',width:150,editor:'text'},  
31.         {field:'status',title:'Status',width:50,align:'center',  
32.             editor:{  
33.                 type:'checkbox',  
34.                 options:{  
35.                     on: 'P',  
36.                     off: ''  
37.                 }  
38.             }  
39.         },  
40.         {field:'action',title:'Action',width:70,align:'center',  
41.             formatter:function(value,row,index){  
42.                 if (row.editing){  
43.                     var s = '<a href="#" onclick="saverow('+index+')">Save</a> ';  
44.                     var c = '<a href="#" onclick="cancelrow('+index+')">Cancel</a>';  
45.                     return s+c;  
46.                 } else {  
47.                     var e = '<a href="#" onclick="editrow('+index+')">Edit</a> ';  
48.                     var d = '<a href="#" onclick="deleterow('+index+')">Delete</a>';  
49.                     return e+d;  
50.                 }  
51.             }  
52.         }  
53.     ]],  
54.     onBeforeEdit:function(index,row){  
55.         row.editing = true;  
56.         $('#tt').datagrid('refreshRow', index);  
57.     },  
58.     onAfterEdit:function(index,row){  
59.         row.editing = false;  
60.         $('#tt').datagrid('refreshRow', index);  
61.     },  
62.     onCancelEdit:function(index,row){  
63.         row.editing = false;  
64.         $('#tt').datagrid('refreshRow', index);  
65.     }  
66. });
