Editable DataGrid 实现列表新增编辑功能

今天在开发一个功能时候，需要直接在列表实现新增、编辑等功能。于是查看easyui 相关文档，找到相关解决办法。
easyui的datagrid支持可编辑功能。它使用户能够向数据网格中添加一个新行。用户也可以更新一个或多个行。

下面是我在项目中的实现代码：
第一步：引用
easyui.css
jquery-1.8.1.min.js
jquery.easyui.min.js
第二步：Html和Javascript代码

<h2>Editable DataGrid Demo</h2>
<div class="demo-info">
<div class="demo-tip icon-tip"> </div>
<div>Click the edit button on the right side of row to start editing.</div>
</div>

<div style="margin:10px 0">
<a href="javascript:void(0)" class="easyui-linkbutton" onclick="insert()">Insert Row</a>
</div>

<table id="tt"></table>

<script>
var products = [
{productid:'FI-SW-01',name:'Koi'},
{productid:'K9-DL-01',name:'Dalmation'},
{productid:'RP-SN-01',name:'Rattlesnake'},
{productid:'RP-LI-02',name:'Iguana'},
{productid:'FL-DSH-01',name:'Manx'},
{productid:'FL-DLH-02',name:'Persian'},
{productid:'AV-CB-01',name:'Amazon Parrot'}
];
$(function(){
$('#tt').datagrid({
title:'Editable DataGrid',
iconCls:'icon-edit',
width:660,
height:250,
singleSelect:true,
idField:'itemid',
url:'data/datagrid_data.json',
columns:[[
{field:'itemid',title:'Item ID',width:60},
{field:'productid',title:'Product',width:100,
formatter:function(value,row){
return row.productname || value;
},
editor:{

},
{field:'listprice',title:'List Price',width:80,align:'right',editor:{type:'numberbox',options:{precision:1}}},

}
}
},
{field:'action',title:'Action',width:80,align:'center',
formatter:function(value,row,index){
if (row.editing){
var s = '<a href="javascript:void(0)" onclick="saverow(this)">Save</a> ';
var c = '<a href="javascript:void(0)" onclick="cancelrow(this)">Cancel</a>';
return s+c;
} else {
var e = '<a href="javascript:void(0)" onclick="editrow(this)">Edit</a> ';
var d = '<a href="javascript:void(0)" onclick="deleterow(this)">Delete</a>';
return e+d;
}
}
}
]],
onEndEdit:function(index,row){
var ed = $(this).datagrid('getEditor', {
index: index,
field: 'productid'
});
row.productname = $(ed.target).combobox('getText');
},
onBeforeEdit:function(index,row){
row.editing = true;
$(this).datagrid('refreshRow', index);
},
onAfterEdit:function(index,row){
row.editing = false;
$(this).datagrid('refreshRow', index);
},
onCancelEdit:function(index,row){
row.editing = false;
$(this).datagrid('refreshRow', index);
}
});
});
function getRowIndex(target){
var tr = $(target).closest('tr.datagrid-row');
return parseInt(tr.attr('datagrid-row-index'));
}
function editrow(target){
$('#tt').datagrid('beginEdit', getRowIndex(target));
}
function deleterow(target){
$.messager.confirm('Confirm','Are you sure?',function(r){
if (r){
$('#tt').datagrid('deleteRow', getRowIndex(target));
}
});
}
function saverow(target){
$('#tt').datagrid('endEdit', getRowIndex(target));
}
function cancelrow(target){
$('#tt').datagrid('cancelEdit', getRowIndex(target));
}
function insert(){
var row = $('#tt').datagrid('getSelected');
if (row){
var index = $('#tt').datagrid('getRowIndex', row);
} else {
index = 0;
}
$('#tt').datagrid('insertRow', {
index: index,
row:{
status:'P'
}
});
$('#tt').datagrid('selectRow',index);
$('#tt').datagrid('beginEdit',index);
}
</script>

希望可以帮到有类似需求的朋友。
