[jQuery] Re: PHP variable into jQuery
Try this.
$(document).ready(function() {
$("input.checkme").click(function() {
$('#eventItems').text(''+$('input.checkme:checkbox:checked'
).length);
});
});

[jQuery] Re: PHP variable into jQuery
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();
}
});
});

[jQuery] Re: PHP variable into jQuery
If all these checkboxes are in the same container where no other
checkboxes are you can use somthing like this
$('#id input:checkbox:checked').length
Or if there are other checkboxes in the way you can give all these
checkboxes the same class name and do
$('#id input.classname:checkbox:checked').length
Think these should both work, if I've understood what you are asking
for.

[jQuery] Re: PHP variable into jQuery
Could you possibly give each checkbox the same class?
$(function(){
$("input.checkMe).click(function(){
if (this.checked) {
$("#eventItems").text(/([0-9]+)$/.exec(this.id)[1]);
} else {
$("#eventItems").empty();
}
});
});
