这是商店:
Ext.define( 'LFinanceCRM.store.Prospect', {
extend : 'Ext.data.Store',
buffered : false,
autoLoad : true,
remoteFilter : true,
storeId : 'prospect-store',
proxy : {
type : 'ajax',
url : 'services/getProspect.php',
filterParam : undefined,
limitParam : undefined,
startParam : undefined,
pageParam : undefined,
idParam : 'id',
reader : {
type : 'json',
root : 'prospect'
}
},
fields : [
{ name : 'id' },
{ name : 'value' }
],
constructor : function(){
this.callParent( arguments );
console.log( 'new ' + this.self.getName());
}
});
这是PHP代码:
<?php
include_once 'db.php';
header( "Content-type: application/json; charset=utf-8" );
$id = @mysql_real_escape_string($_GET['id']);
$link = db_open();
$query = "SELECT name, value FROM Pairs WHERE id = '$id'";
$result = @mysql_query( $query, $link );
$pairs = array();
if( $result ) {
while( $row = mysql_fetch_assoc( $result )) {
$item = Array();
$item['id' ] = $row['name' ];
$item['value'] = $row['value'];
$pairs[] = $item;
}
}
$response = array( 'prospect' => $pairs );
print json_encode( $response );
@mysql_free_result( $result );
@mysql_close( $link );
?>
这是从 PHP 收到的 JSON:
{prospect:[
{id:'aaa',value:'vvvv'},
{id:'bbb',value:'vvvv'},
...
{id:'yyy',value:'vvvv'},
{id:'zzz',value:'vvvv'},
}]
这是视图:
Ext.define( 'LFinanceCRM.view.RawDataView', {
extend : 'Ext.grid.Panel',
requires :[],
alias : 'widget.raw-data-view',
autoScroll : true,
title : 'Données brutes',
columnLines : true,
viewConfig : { stripeRows : true },
store : Ext.data.StoreManager.lookup( 'prospect-store' ),
columns : [{
text : 'Nom',
dataIndex : 'name',
sortable : false,
width : '29%'
},{
text : 'Valeur',
dataIndex : 'value',
sortable : true,
width : '70%'
}],
constructor : function() {
this.callParent( arguments );
console.log('new ' + this.self.getName());
}
});
我使用 Sencha 应用构建工具支持的 MVC 模式,这里是控制器:
Ext.define( 'LFinanceCRM.controller.Main', {
extend : 'Ext.app.Controller',
id : 'theController',
onNonLuesSelectionChanged : function( panel, selected, eOpts ) {
console.log('onNonLuesSelectionChanged: ' + selected[0].data.id );
this.getStore('Prospect').load({
id : selected[0].data.id,
callback : function( records, operation, success ) {
var pairs = [];
for( var i = 0; i < records.length; ++i ) {
pairs.push( records[i].data );
}
Ext.ComponentQuery.query('client-view')[0].getForm().setValues( pairs );
Ext.ComponentQuery.query('immo-view' )[0].getForm().setValues( pairs );
}
});
},
onSavePairs : function() {
console.log('onSavePairs');
},
...
onMail : function() {
console.log('onMail');
},
...
stores : ['Prospect'],
constructor : function(){
this.callParent( arguments );
console.log( 'new ' + this.self.getName());
this.control({
'#ProspectsTableNonLues' : { selectionchange : this.onNonLuesSelectionChanged },
...
'#savePairsButton' : { click : this.onSavePairs },
...
'#mail' : { click : this.onMail },
});
}
});

我的问题是:如何将数据从存储转换为视图?
