I have a problem need us to help me.
The problem is that:
I want to update the treegrid by button, so I give the button a ajax request function and if response is success, then update the tree grid, the method I wrote like this.
model:
Ext.define('SH_UDC.model.GSingleSearch.GSingleModel', {
extend: 'Ext.data.Model',
fields: [
{
name: 'id'
},
{
name: 'name'
},
{
name: 'value'
}
]
});
store:
Ext.define('SH_UDC.store.GSingleSearch.GSingleStore', {
extend: 'Ext.data.TreeStore',
storeId:'GsingleStore',
requires: [
'SH_UDC.model.GSingleSearch.GSingleModel'
],
model: 'SH_UDC.model.GSingleSearch.GSingleModel',
autoLoad: false,
proxy: {
type: 'ajax',
url: Urls.GSearch,
reader: {
type: 'json',
root: 'data'
}
}
});
view:
singlelist.js
Ext.define('SH_UDC.view.GSingleSearch.SingleList', {
extend: 'Ext.tree.Panel',
alias:'widget.singlelist',
id: 'ae',
height: 250,
width: 400,
columnLines: true,
rowLines: true,
store:'GSingleSearch.GSingleStore',
rootVisible: false,
initComponent: function() {
var me = this;
Ext.applyIf(me, {
viewConfig: {
},
columns: [
{
xtype: 'treecolumn',
dataIndex: 'name',
text: 'Name',
flex: 1,
renderer: function(value) {
if(translations[value]){
return translations[value];
}else{
return value;
}
},
},
{
xtype: 'gridcolumn',
dataIndex: 'value',
text: 'Value',
flex: 1,
},
{
xtype: 'gridcolumn',
dataIndex: 'value',
text: '中文解释',
flex: 3,
renderer: function(value) {
if(translations[value]){
return translations[value];
}else{
return value;
}
},
}
]
});
me.callParent(arguments);
}
});
GsingleView.js
Ext.define('SH_UDC.view.GSingleSearch.GSingleView', {
extend: 'Ext.form.Panel',
alias: 'widget.individualuser',
requires:[
'SH_UDC.view.GSingleSearch.SingleList',
],
layout: {
type: 'fit'
},
initComponent: function() {
var me = this;
Ext.applyIf(me, {
dockedItems: [
{
xtype: 'toolbar',
dock: 'top',
items: [
{
xtype: 'combobox',
fieldLabel: 'UDC',
store:UdcStore,
fieldLabel: 'UDC',
labelAlign: 'right',
labelWidth: 50,
mode:'local',
selectOnFocus:true,
triggerAction:"all",
displayField:"set_name",//
valueField:"id",//实
labelWidth: 50
},
{
xtype: 'textfield',
itemId:'msisdnnum',
width: 200,
hideLabel: true,
inputType: 'tel',
labelWidth: 150
},
{
xtype: 'button',
width: 100,
text: 'Search',
itemId:'searchbutton'
}
]
}
],
items: [
{
xtype: 'singlelist'
}
]
});
me.callParent(arguments);
}
});
controller:
Ext.define('SH_UDC.controller.GSingleSearch.GSingleController', {
extend: 'Ext.app.Controller',
requires: [
'SH_UDC.util.Util',
],
views: [
'GSingleSearch.GSingleView',
'GSingleSearch.SingleList'
],
stores:[
'GSingleSearch.GSingleStore'
],
refs: [
{
ref: 'singleList',
selector: 'singlelist'
},
],
init: function(application) {
this.control({
"individualuser singlelist": {
render: this.onRender
},
"individualuser button#searchbutton": {
click: this.onButtonClicksearch
},
});
},
onRender: function(component, options) {
},
onButtonClicksearch:function(button,e,options){
var toolbar = button.up('toolbar'),
udcid = toolbar.down('combo').getValue(),//udc id
cell = toolbar.down('textfield[itemId=msisdnnum]').getValue();//Input Number
var Tree = this.getSingleList().getStore();
if(udcid!=null&&cell.length>4&&cell.length<15){
Ext.Ajax.request({
url: Urls.GSearch,
method: 'post',
headers:{'Content-Type':'application/json;charset=utf-8'},
jsonData:{"nodeId": udcid,"cell": cell},
success: function(conn, response, options, eOpts) {
//Ext.get(login.getEl()).unmask();
var result = SH_UDC.util.Util.decodeJSON(conn.responseText);
var ec = result.data;
if (result.success) {
Tree.load(ec);
} else {
SH_UDC.util.Util.showErrorMsg(conn.responseText);
}
},
failure: function(conn, response, options, eOpts) {
SH_UDC.util.Util.showErrorMsg(conn.responseText);
}
});
}
}
});
But the response has two, one come from controller, and the other from TreeStore. And the awful thing is the ajax request from controller cannot update the treestore or treegrid, but the store's request works. It can not give the write response! I want to get the response after I give the request with some conditions.

In controller, I don't know how to program that I can update the tree grid by ajax response. Pls Help!!!!
Empty text does not expand the container it is in.
