How to find invoked element without passing this
<p>I have a Javascript function called many times from many pages. </p>

<p>Inside this function I have to check the element which is invoked this function.</p>

<p>I know a method to pass 'this' with the function call. I cannot use that method. Because I am working only on a single module. 
There are many other modules using this function. So if I change the function definition it will throw error for other modules/pages. </p>

<p>Is there any other way to find the invoked element without passing 'this' or without changing the function definition.  </p>
