先上图
grid分页：
把grid和page工具绑定在一起
 // create the Data Store
  var store = new Ext.data.Store( {
 url:'termSearch.action',
storeId:'searchResult',
  reader: new Ext.data.JsonReader({
totalProperty: 'totalrows',
root: 'data',
fields: [
{name: 'id', type:'int'},
'consumer',
'area',
'termid',
'name',
'status',
'udate'
]
 })
 });
var sm = new Ext.grid.CheckboxSelectionModel();// 多选行
var cm = new Ext.grid.ColumnModel([
new Ext.grid.RowNumberer(),
sm,
{header:'序号',width:40,dataIndex:'id'},
{header:'用户',width:50,dataIndex:'consumer'},
{header:'地域',width:50,dataIndex:'area'},
{header:'终端编号',dataIndex:'termid'},
{header:'终端名称',dataIndex:'name'},
{header:'终端状态',dataIndex:'status',renderer: statusColor},
{header:'更新日期',dataIndex:'udate'}
]);
// by default columns are sortable
cm.defaultSortable = true;
var grid = new Ext.grid.GridPanel({
store: store,
cm: cm,
stripeRows: true,
height:350,
width:800,
title:'',
tbar: new Ext.PagingToolbar({
pageSize: 10,
width:'98%',
store: store,
displayInfo: true,
displayMsg: '显示第 {0} 条到 {1} 条记录，共 {2} 条',
emptyMsg: "无记录"
})
});
窗口布局：
Ext2有很多布局，就是在layout包下，我这里用了TableLayout，TableLayout其实就是和一个HTML中的表格一样，可以作row和column的span
var table = new Ext.Panel({
layout:'table',
defaults: {
bodyStyle:'padding:1px'
},
layoutConfig: {
columns: 4
},
items: [{
width:165,
layout: 'form',
labelWidth:55,
items: [{
xtype:'textfield',
fieldLabel: '终端编号',
name: 'termId',
id:'termId',
anchor:'95%'
}]
},{
width:165,
layout: 'form',
labelWidth:55,
items: [{
xtype:'textfield',
fieldLabel: '终端名称',
name: 'termName',
id:'termName',
anchor:'95%'
}]
},{
width:165,
layout: 'form',
labelWidth:55,
items: [{
xtype:'textfield',
fieldLabel: '刷新延时',
name: 'timeLapse',
id:'timeLapse',
anchor:'95%',
xtype:'combo',
store: new Ext.data.Store({
proxy: new Ext.data.MemoryProxy([['0','0'],['5','5'],['10','10'],['15','15'],['20','20']]),
reader: new Ext.data.ArrayReader({}, [
{name: 'value',mapping: 0, type: 'int'},
{name: 'text',mapping: 1}
]),
autoLoad:true
}) ,
displayField:'text',
valueField:'value',
hiddenName:'timeLapseValue',
typeAhead: true,
triggerAction: 'all',
forceSelection:true
}],
colspan:2
},{
width:165,
layout: 'form',
labelWidth:55,
items: [{
xtype:'textfield',
fieldLabel: '用户',
name: 'consumerId',
anchor:'95%',
id: 'consId',
xtype:'combo',
anchor:'95%',
store: consumerStore,
displayField:'text',
valueField:'value',
hiddenName:'consumerId',
typeAhead: true,
mode: 'local',
triggerAction: 'all',
forceSelection : true,
emptyText:'Select a user',
allowBlank: false,
selectOnFocus:true,
forceSelection:true,
listeners:{
select:{
fn:function(combo,record,index) {
var store = getSelectStore("55",record.get('value'));
Ext.getCmp('areaId').clearValue();
Ext.getCmp('areaId').store = store;
if(Ext.getCmp('areaId').view){
Ext.getCmp('areaId').view.setStore(store);
}
Ext.getCmp('areaId').enable();
}
}
}
}]
},{
width:165,
layout: 'form',
labelWidth:55,
items: [{
xtype:'textfield',
fieldLabel: '地域',
name: 'consumerArea',
id:'areaId',
anchor:'95%',
xtype:'combo',
store: new Ext.data.Store(),
displayField:'text',
valueField:'value',
hiddenName:'consumerAreaId',
typeAhead: true,
mode: 'local',
triggerAction: 'all',
forceSelection : true,
emptyText:'Select a area',
allowBlank: false,
selectOnFocus:true,
forceSelection:true,
disabled:true
}]
},{
width:165,
layout: 'form',
labelWidth:55,
items: [{
xtype:'textfield',
fieldLabel: '终端状态',
name: 'termStatus',
id:'termStatus',
anchor:'95%',
xtype:'combo',
store: termStatusStore,
displayField:'text',
valueField:'value',
hiddenName:'termStatusId',
typeAhead: true,
triggerAction: 'all',
forceSelection:true,
editable:false,
mode: 'local'
}]
},{
layout: 'form',
labelWidth:55,
items: [{
name: 'Save',
id: 'Save',
text: '查询',
xtype:'button'
}]
}]
});
下拉框级联：
下拉框级联的思路其实很简单，就是在第一个的select事件中刷新跌入下拉框的store。这里问题主要在如何给第二个下拉框的store赋值，我这里是用了一个方法获得一个新的store，然后赋值的。不仅要各combo赋值，还要给combo.view赋值。一开始就卡在这里了，物理如何我给combo赋值后，下拉框中的值总是不能够及时刷新。给combo.view赋值是需要使用combo.view.setStore(store)这个方法，而不能直接赋值。在赋值的时候需要检查combo.view 是否存在。
var store = getSelectStore("55",record.get('value'));
Ext.getCmp('areaId').clearValue();
Ext.getCmp('areaId').store = store;
if(Ext.getCmp('areaId').view){
Ext.getCmp('areaId').view.setStore(store);
}
Ext.getCmp('areaId').enable();
