Uncaught TypeError: Cannot call method 'request' of undefined
Solution 1
Usually, when the error is of the form Cannot call method 'X' of undefined
, it means that whatever object you are attempting to call X
from does not exist.
In your case, it appears as though Ext.Ajax
is undefined. The easiest way to resolve this involves two simple steps:
- Make sure that you've included the javascript file that creates
Ext.Ajax
. If you're using theext-all.js
file, then you shouldn't have to worry about this. -
Make sure that none of your code executes until the browser is ready. The best way to do this is to wrap all of your code within a
Ext.onReady()
call. I've provided an example below.Ext.onReady( function() { //your code goes here });
You can see more examples of this at the ExtJS Examples page.
Solution 2
Got bitten by this problem too.
The solution is for you to call Ext.require('Ext.Ajax')
before Ext.onReady
like so:
Ext.require('Ext.Ajax');
Ext.onReady(function() {
Ext.Ajax.request({
// your code here...
});

In my javascript code, I keep getting the following error:
Uncaught TypeError: Cannot call method 'request' of undefined
My Javascript is below. Any assistance would be greatly appreciated!
myJsonStore = { store1: new Ext.data.JsonStore({ root: 'rootstore1', fields: ['UserID', 'UserName'] }) }; //------My panel------ items: [{ xtype: 'combo', id: 'UName', fieldLabel: 'User', emptyText: 'All', store: myJsonStore.store1, displayField: 'UserName', valueField: 'UserID' }] //-------------------- Ext.Ajax.request({ url: "rPages/rLogMatchOdds.aspx", params: { m: 'init' }, success: function(response) { var data = Ext.decode(response.responseText); myJsonStore.store1.loadData(data); } }); Ext.getCmp('UName').store.on('load', function(my, rec) { Ext.getCmp('UName').setValue(rec[0].get('UserName')); }, this);

NT3RP about 13 yearsIf you are using
ext-all.js
, have you tried the second suggestion? -
