Filling textboxes in a webpage automatically
<p>I've been asked to fill a form by my university which has 323 textboxes where each of them has to contain a number between 1 and 323. After manually adding a few numbers till 80 for example, I want a write a script that fills all the remaining textboxes with the numbers which have not been used. </p>

<p>How can this be accomplished? I mean, what should I use to accomplish this? If I make a JS script how do I run it on this page. Or is there some other way?</p>

<p>Thanks.</p>
