Question

Can anyone help me with javascript that hides divs matching a specific random number? Every time I load this page it has two divs like <div id='1945498985'> the number changes every page load but remains between 9-10 in length how would I fetch the two divs on the page and remove/hide them?

Let me clarify the two divs on this page each have a random number between 9 and 10 in length.

One such div looks like this:

<div id='843401712' style='position:relative;z-index: 1000;left: 75px;top: -340px; padding:0px; margin: 0px;width: 310px; height:280px; text-align: center; border:3px gray solid'></div>

I do not have control over the generated html I am looking to run javascript alongside a page as a greasemonkey extension to hide these two divs.

Thanks for any help you guys offer, I’m new to javascript so its a big help.

Use document.getElementsByTagName() to fetch all div elements. Then, check their id using maybe a regular expression like [0-9]{9,10} and if the id matches, remove/hide them.
