Question

I have one form on a page and within that form there will be a check box for every row in the table. I need to count the number of rows that have a checked row, but I am having trouble even selecting that from jQuery.

Here is what my code looks like for a checkbox:

<input type="checkbox" id="onHomePage_56" name="onHomePage" 
    value="56" checked="checked">

An unchecked box doesn’t have checked=”checked”.

Answer 1

var q = $('form#id-of-form').find('input:checked').length;

If there are checkboxes in the form you don’t want counted, then add a class to the ones you do want counted and select those instead:

var q = $('form#id-of-form').find('input.count-these:checked').length;
