Real newbie question

[bazianm]

Hi,

I have a page that I want to trace through some validation code. The
problem is that i do not know what code is running. I don't know what
event is firing or anything like that. The generated HTML (it is php
based) does not show anything on the <INPUT> tag to tell me what is
being called and I can only guess that some event handler is being
attached to the form somewhere. Obviously, this is not my code and I
am unfamiliar with the framework used. I have to fix this bug because
the developer went AWOL on me.

In many programming languages, I can put a break point to stop on the
next line of code executed. What I was hoping to do was get into the
element with the problem, set a breakpoint to activate whenever a line
of code is executed. This way, when I tab off the object, it would
indiscriminately stop when any javascript is executed.

I have never used Firebug before and time is short. Can I do what I
want? If so, how?

Thanks

You can do the same in Firebug

1) Select the Script panel and enable it
2) Reload the page
3) Click on "Break on Next" (the orange pause button on the toolbar
left side)
4) Do whatever you want on the page and Firebug will break on the
first line executed
