View Full Version : Can not get store.length

15 Nov 2011, 9:01 AM
Hi, I have problem with simple store:

ColumnSizeStore722 = Ext.create('Ext.data.JsonStore', {
autoLoad: false,
autoSync: true,
storeId: 'ColumnSizeStore722',
proxy: {
type: 'ajax',
url: './php/SelectColumnSize.php?GridName='+GridName,
reader: {
type: 'json',
root: 'data'
fields: [
name: 'size'
listeners: {
load: function() {
StoreLength = ColumnSizeStore722.data.length;
alert(StoreLength); //show 15
alert(StoreLength); //show "0". WHY???

Why I can not get ColumnSizeStore722.data.length after store load? How can I fix this? Thanks

Why not use store.getCount (http://docs.sencha.com/ext-js/4-0/#%21/api/Ext.data.Store-method-getCount)()?

store.getCount() would show the same. You're missing the fact that store.load is async, you have to do whatever post processing you need in the 'load' listener handler.

Thank you for quick answer!
Actually it is only example, On real case I need to get record from ColumnSizeStore722.data.items[i].size
But my store is empty :-(
