Question

I’m using jQuery Mobile Ajax navigation feature, And I need to change a variable that is defined inside external js file, So I can’t put my definition before I load that js file…

So, How to change value of a variable for external javascript file after the js file is defined?

(That external js file includes events)

---

So this question is not duplicate of that question.

Update

My JS File contains events, something like this: $(document).on('mousemove','#main',function() { /*something*/} );

And I need that variable. Is it possible to pass variable to that?

I have tried simply changing that variable i = 5;, but I’m getting undefined error.

Update 2

The external JS file is something for some pages that are almost same, but a little different, just one or two parameters.

And I simply want to pass the parameters to that JS file. Is it possible? How?

Answer 1

Let’s assume http://www.example.com/external.js defines variable foo, which you want to change.

<script src="http://www.example.com/external.js"></script>
<script type="text/javascript">
    foo = "my new value";
</script>

This assumes that external.js defined foo in the global scope. If it’s defined in an anonymous function or similar, you won’t be able to change the value.
