Question

I want to write a script which will click a button on an external website (one which belongs to someone else). The button is defined as follows:

<input class="btnAdd" type="image" src="/superstore/i/b/btnAdd.gif" 
    id="i61109534-a" onclick="return a(61109534);">

Basically I want to have a button on my website that when pressed, redirects the user to the external website and automatically triggers the above onclick event. I have been using PHP so far but don’t mind if the solution is using Javascript or anything else for that matter!

As far as I know, that’s how most tracking, ads and put-a-widget-in-your-site systems work. You just need to insert a call to the *.js file where the function is defined. From the source code of StackOverflow:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>

Of course, you must kind of trust the remote site…
