Returning a value to an onclick event

[nareshreporter]

Hi,
I have an external javascript function that returns a value. But im calling this function when ever user clicks a button (onclick event). How do i access that value in my html page.

EXAMPLE:

IN HTML:
<input type="button" name="btn" onclick="addNumbers(var1, var2)"

IN .JS FILE:
function addNumbers(num1, num2)
{
return num1 + num2;
}

Now how do i access this value in HTML page.

I appreciate if anyone could help me out.
Thanks in advance

Assuming you mean access the return value of the function, there are two ways:

1. Save it in a JS variable, and then access that variable, or

2. Call the function only when you need the result, and use the result directly.

Hope this helps,
