Firebug - Break on Error - d is undefined

I've created a website that used to work fine. But now Firebug throws me an error while loading:

Break on Error - d is undefin开发者_如何转开发ed (in jquery, gets loade from the google CDN)

if i turn off firebug and reload the page everything works just fine.

the site is now at http://www.optiekmeulemeester.be/test and I wanna hear if other get the same error and what can I do about it?

thanks in advance

We have to add a ref of /jquery.validate.min.js in this order

<script src='@Url.Content("~/Scripts/jquery-1.5.1.min.js")' type="text/javascript"></script>
<script src='@Url.Content("~/Scripts/jquery.validate.min.js")' type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

works fine try this.....

The problem is you activated 'Break on all error' firebug option (it's the pause icon on the Console tab in my firebug 1.5.4) so that means that it will break on any javascript error, so now you wonder how is possible that jquery has javascript errors that makes this option to break, well, jquery and jqueryui has code like following:

try {
  o.ajaxOptions.success(r, s);
} catch (e) {}

If the success method does not exist that is a javascript error, and that is when firebug kicks in, but firebug is not able to know that error will be handled in a catch statement, and that is why you dont see any error when normally executing the code (ie. without firebug). As a side note I found this mail about someone asking for firebug 'break on all errors' to be aware of errors inside catch statements and not break on them.

So, the solution is to deactivate the 'break on all errors' firebug option by:
- Clicking in the Pause icon on the Console tab (this is in firebug 1.5.4)

Or as already said, the more general approach of executing Tools -> Firebug -> Options -> Reset All Firebug Options (which will make the 'Break on all errors' go to its default off state)

If you think this is a firebug bug, then what is the issue number?

I'm not getting any error, but I have had that same errand message popup before. It's never a real error, my guess is it's a bug in firebug. Oh the irony.

That's because you're using a breakpoint inside of an ajax call, without stop it before to do the call, try using 2 breakpoints, 1 inside, and 1 BEFORE to use the ajax call, and in that way it will work.

It's a firebug bug.
