How to call a javaScript Function

I have a function onChangeBrand() in A.js and there is a same name in B.js.

So how to avoid this situation? There is a constraint - I can't change the function names. and i am not allowed to edit both the Js files so namespace is not a right idea for me.

Can we call something like A.onChangeBrand() or B.onChangeBrand()?

Ok, if namespaces are not for you and you can put your code in between the script tags loading these files

<script src='a.js'></script>
<script>
var a_onChangeBrand = onChangeBrand; // copy the function
</script>
<script src='b.js'></script>

after that a_onChangeBrand() will call the function from a.js and onChangeBrand() from b.js

But nothing will help you if some functions in those a.js and b.js are also using these functions - they might call function from the last file loaded.

If you don't have access to the source, then the following is a solution (not the prettiest, mind you):

<script src="http://exmpale.com/a.js"></script>
<script>
 A = { onChangeBrand:onChangeBrand };
</script>

<script src="http://exmpale.com/b.js"></script>
<script>
 B = { onChangeBrand:onChangeBrand };
</script>

The two functions are now namespaced and can be invoked like so:

A.onChangeBrand();     
B.onChangeBrand();

You can do this to one of your function..

var myNS = new (function() {

    this.onChangeBrand= function() {
        alert('hello!');
    };

})();

and then call myNS.onChangeBrand();

Similarly use myNS2 for other function. These are called as namespaces.

Check how to use namespaces in JavaScript if you can edit these two files a.js and b.js then you can declare namespaces. See best answer here : How do I declare a namespace in JavaScript?
