可編輯的功能已經(jīng)添加到數(shù)據(jù)網(wǎng)格中了，它使用戶能夠添加新的行到數(shù)據(jù)網(wǎng)格中，用戶還可以更新一個或多個行。本教程將介紹如何創(chuàng)建一個具有內(nèi)聯(lián)編輯功能的數(shù)據(jù)網(wǎng)格。

創(chuàng)建數(shù)據(jù)網(wǎng)格

$(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:{
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:180,editor:'text'},
{field:'status',title:'Status',width:50,align:'center',
editor:{
type:'checkbox',
options:{
on: 'P',
off: ''
}
}
},
{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);
}
});
});

想要在數(shù)據(jù)網(wǎng)格中啟用編輯功能，您需要添加一個編輯器屬性到列中。編輯器會告訴數(shù)據(jù)網(wǎng)格如何編輯字段以及如何保存字段值，我們定義了三個編輯器：text、combobox和checkbox。

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));
}
