How change the videos max of page with jQuery ?

Question

I have one website here that contains videos to see, like youtube, and the videos are divided in pages, and in the source of this page I got this part of the source:

<input type="hidden" value="12" id="vid_count">
<input type="hidden" value="422" id="vid_max">
<input type="hidden" value="12" id="vids_per_page">

The site contains 422 videos with 36 pages, 12 videos per page

I need to show all videos in only one page...

I've already tried

document.getElementById("vids_per_page").setAttribute("value", "500");

but this doesn't work...

How can I do it? (via greasemonkey)

any additional info?

Answer 1

If it's just about changing values, this will do the trick:

document.getElementById("vids_per_page").value = document.getElementById("vid_max").value;

I don't know what vid_count means, so you might also need to do this:

document.getElementById("vids_per_page").value = document.getElementById("vid_max").value;

Are you sure vid_count isn't 422? Just to be sure, try this:

document.getElementById("vids_per_page").value = "422";
