Question

as part of a script i am working on i have the following:

loop
if($(element).find(selector))
{ do stuff }
else
{ do other stuff }
/loop

The idea is that there are two versions of the elements getting looped and I need to distinguish between them (based on content) to determine which actions to take.

This works great if find is successful. If it is not, then the script has a fatal error.

I can’t find any documentation on what happens when find fails. How do I make this work?

Answer 1

How about this?

if($(element).find(selector).length > 0)
{ do stuff }

It’s a little longer, but ought to work.

Looks to me like your original find test always evaluates to true. Testing the length gets you a boolean result to evaluate.
