Passing Parameters By Reference In JavaScript?
<p>I have a technical challenge that I'm trying to figure out the best way to solve.  Here's the scenario.</p>

<p>I have one HTML page that launches another HTML page...let's call it main.html that has a button which calls test.html  Inside test.html the user can answer a series of questions and submit the results to a Learning Management System.  Each time they do a test I have a JavaScript variable inside the test.html page that gets incremented from A to B to C, etc.  For example, if they take the test the first time it will Be something like 0001A and the second time 0001B.</p>

<p>This works great, but if they close the test.html page, since this JavaScript variable is inside it, the counter will start off at 0001A again if the user tries to take another test.  What I would like is for the next test the user submits to be 0001C.  Not sure how to do this...</p>

<p>I thought of passing a variable to the test.html page via something like:  test.html&amp;id=C
but this means that main.html that calls test.html would need to know that the user has already done two tests and I'm not sure you can pass a value back from an HTML page to the HTML page that called it?</p>

<p>Anyway, I'm wondering what would be the best way to solve this problem?</p>

<p>Thanks</p>
