E.fireFn.apply is not a function

[captainm1uk]

Hi
I have a message box set on the onReady state of a form - the prompt comes up ok but I get the above error in FF - can anyone help

<script type='text/javascript'>
Ext.onReady(
Ext.MessageBox.show({
title:'System Message',
msg: 'Blah blah, blah',
buttons: Ext.MessageBox.OK,
fn: showResult,
icon: Ext.MessageBox.QUESTION
}))();

function showResult (btn) {
if (btn=='ok') {window.close();}
}
</script>

Thanks

Ext.onReady must be passed a function reference.

What you are passing there, if you read your code, is the result from Ext.MessageBox.show

Yes - when the page loads, a prompt box comes up then they press ok and the window closes

[Animal]

Yes, and the result from that call is passed into Ext.onReady which if you read its docs, expects to be passed a reference to a function which it executes when the DOM is ready.

It attempts to make a call to whatever the return value of Ext.MessageBox.show() is!

Sorry you have lost me !!!

[Animal]

OK.

Ext.onReady accepts a function as it's parameter.

It will call this function when the DOM is ready.

Clear so far?

I think so - isn't this is what it is doing already?? Ext.onReady(......

[Animal]

OK, you realize you need to pass a function object into Ext.onReady?

[captainm1uk]

yes
so i am back to square one - the function is being passed yet i still get the error message

Am i missing something ?

Stop running ahead.

You are NOT passing a function.

You are passing the return value from a call to Ext.MessageBox.show!
