This is just a sample of the code, there are alot more functions, but I thought the error might be related to surrounding code. I have absolutely no idea why, as I know all the surrounding functions execute, and First_Array is populated.

However when I click the Proceed to Second button, the onclick attribute does not execute because Firebug says proceedToSecond is not a function

button code:

<input type="button" id="proceed" name="proceedToSecond" onclick="proceedToSecond();" value="Proceed to second form">

Answer 1

Maybe there is an error in your Javascript before that snippet given by you. If so, the rest will not be parsed by Firefox and then your function will not be defined.

Answer 2

The problem was resolved by changing proceedToSecond() to doIt() in both the call and the function name. I have no idea why

Answer 3

Hmm... I always used javascript:function_name() instead of function_name() because a few times the javascript didn't run. The name tag for the html snippet might have to be changed to a slightly different name because javascript might be getting it mixed up. Can you show us the entire javascript file because there may be a mistake/syntax error somewhere at the bottom/top.

Answer 4

It works on my computer, Firefox 3.5.5, Firebug 1.4.3, when inserting your code into an empty html document (<html><head/><body> code </body></html>)

Maybe there is another bug somewhere in your DOM, or in some of your other functions?

Could you possibly paste the entire source here, or maybe on a pastebin site?

Answer 5

I had the same problem, and it's because you have a form with the same name as your function. JavaScript doesn't seem to be able to distinguish between the two, so you get the "not a function" error.
