[jQuery] Re: PHP variable into jQuery

[choffman]

Giving the check boxes the same class helped.  Thanks. I've only been
using jQuery for a short time, I'm trying to learn the ins and outs of
it.

I changed the code back to use length.  Otherwise, I was just getting
the value of the checkboxes.  I would like to know how many boxes are
checked and have it update itself when boxes are checked or
unchecked.

For example, if I have 6 checkboxes and 3 are checked the output
should show 3. If I uncheck one it should 2 and vice versa.

The result get sent to a div, in this case #eventItems.

$(document).ready(function() {
        $("input.checkme").click(function() {
                        if (this.checked == true) {
                                var event_id = $("#eventItems").length;
                                 $("#eventItems").text(event_id) + 1;
                   } else {
                      $("#eventItems").empty();
                  }
        });
});
