I've just defined a combobox. Firstly it loads a country
list and when select a value it's fire a change
event which doing a ajax
query to DB within searching service;
The thing; this configuration works pretty well when I click and open combobox items. But when I'm typing to combobox's field it's fires listener's store.load
and because of none of country selected yet, the search query url gives not found errors of course.
{
xtype: 'countrycombo',
itemId: 'countryName',
name:'country',
afterLabelTextTpl: MyApp.Globals.required,
allowBlank: false,
flex: 1,
// forceSelection: false,
// typeAhead: true,
// typeAheadDelay: 50,
store: {
proxy: {
type: 'ajax',
// isSynchronous: true,
url: MyApp.Globals.getUrl() + '/country/list?limit=250',
// timeout: 300000,
reader: {
type: 'json',
rootProperty: 'data'
}
},
pageSize: 0,
sorters: 'description',
autoLoad: true
}
,
listeners: {
change: function (combo, countryId) {
var cityStore = Ext.getStore('cityCombo');
cityStore.getProxy()
.setUrl(MyAppp.Globals.getUrl() + '/city/view/search?query=countryid:'+ countryId);
// Ext.defer(cityStore.load, 100);
cityStore.load();
}
}
},
I've tried several things as you see in code above to set a delay/timeout for load during typing to combobox text field; Ext.defer
, timeout
config on proxy, typeAhead
config on combo but none of them worked!
I thought that Ext.defer
is the best solution but it gives this error:
Uncaught TypeError: me.getAsynchronousLoad is not a function at load (ProxyStore.js?_dc=15169)
How can I set a delay/timeout to combobox to fires load
function?
