Yes I’ve found that it’s “undefined” in Firebug, which led to this little thread haha. I was just curious as to “why” it’s undefined and doesn’t bubble up to the object that called the function. Maybe just wishful thinking ;)
Before I read this, I changed my function to do exactly what you’ve stated. So.. good call!
I will definitely give that link a read. Thanks for your help!
It’s a matter of scope. When you run a function, it can only use the data it’s given. If inside “Function A” you want to call “Function B”, then “Function B” doesn’t automatically get to use all the data (variables, functions, arrays, etc.) that exist in “Function A” unless you specially pass “Function B” the data.
This is a must in order to prevent conflictions. What if “Function A” and “Function B” use a variable with the same name? Then simply calling “Function B” would screw “Function A” up.
In your case, you are handing the **specific element data** that “this” refers to to the removeBtn function. So now removeBtn knows what your talking about.
Scope of variables is something I’m always keeping in mind, or else I’d go nuts haha.
But the $(this) object sometimes escapes me when calling multiple functions from functions. It doesn’t seem to behave the same as having an “undeclared” or “undefined” variable… as often $(this) does end up being an object or something in the hierarchy of the program.
Light has been shed. And I am now a better person than I was this morning ;)
Thanks again peeps!
