[Dojo-interest] Re: Dojo-interest Digest, Vol 16, Issue 103

Tue Apr 18 20:36:04 MDT 2006

I was following the tutorial on the following page:

http://dojo.jot.com/WikiHome/Tutorials/HelloWorld#Introduction

I inserted a line:

    alert(dojo)

to show that the module dojo was indeed loaded successfully.
The resulted html page shows a button that shows no reaction when clicked.
It seems to me that the line:

    dojo.event.connect

doesn't work at all. The line:

    helloButton = dojo.widget.byId('helloButton')

was shown not working either ( alert(helloButton) returns 'undefined')

Can someone tell what's going wrong ?
