Getting the value of a hidden input field is undefined

All, I have the following code:

$.infinitescroll.prototype.pageNumber = $("#pagenumber_" + selector).val();
alert($.infinitescroll.prototype.pageNumber);

The alert says undefined. Here is my HTML:

<input type="hidden" id="pagenumber_.category-dj" value="20">

When I do an alert like this:

alert("#pagenumber_" + selector);

These match, why is my val() coming up as undefined?

A period . indicates a class in a CSS selector. One option is use an attribute selector instead to select the element by ID.

$("[id='pagenumber_" + selector + "']").val();

You need to escape the . as this has a special meaning in a jquery selector. It needs to be \\..
