Hello,
A bunch of my JavaScript code is in an external file called helpers.js. Inside the HTML that calls this JavaScript code I find myself in need of knowing if a certain function from helpers.js has been called.
I have attempted to create a global variable by defining:
var myFunctionTag = true;
In global scope both in my HTML code and in helpers.js.
Heres what my html code looks like:
<html>
...
<script type='text/javascript' src='js/helpers.js'></script>
...
<script>
var myFunctionTag = false;
...
//I try to use myFunctionTag here but it is always false, even though it has been se t to 'true' in helpers.js
</script>
Is what I am trying to do even doable?
Thanks,
