First off, sorry for the vague question, I had no idea how to put this into words. My problem is best illustrated by an example.
I am using a bootstrap dropdown menu with several checkboxes in it. I have used a css trick to change their appearance, using some nice FontAwesome icons. However, when I'm trying to do something with the state of these checkboxes using jQuery, the first check/uncheck seems to work, but any subsequent toggle (check/uncheck) doesn't work...
$('.js-inputhit').click(function() {
if (this === event.target) {
$(this).find(':input').click();
}
});
$('.js-inputhit :input').click(function(e) {
e.stopPropagation();
});
$('.selectchat_all').click(function() {
$('.selectchat_active').attr('checked', false);
$('#chat1, #chat2, #chat3, #chat4').attr('checked', true);
});
$('.selectchat_active').click(function() {
$('.selectchat_all').attr('checked', false);
$('#chat1, #chat2, #chat3, #chat4').attr('checked', false);
});/*Adding custom checkbox icons*/

<label for="all" style="font-weight: normal; margin-bottom: 0px;">Check all</label>Problem in this example: Clicking "Check all" checks all 4 channels. Clicking "Check none" unchecks all of them. (so far so good). However, after that, the "Check all" no longer works. It doesn't check the 4 channels anymore. "Check none" still unchecks all of them (if you manually check them), but "Check all" no longer works...
Can anyone find my problem :)? Thank you so much for your assistance.

Reset to default 7Use .prop() instead of .attr()
attr() only updates the actual DOM tree
for more info, see http://api.jquery./prop/ or this answer
$('.js-inputhit').click(function() {
if (this === event.target) {
$(this).find(':input').click();
}
});
$('.js-inputhit :input').click(function(e) {
e.stopPropagation();
});
$('.selectchat_all').click(function() {
$('.selectchat_active').prop('checked', false);
$('#chat1, #chat2, #chat3, #chat4').prop('checked', true);
});
$('.selectchat_active').click(function() {
$('.selectchat_all').prop('checked', false);
$('#chat1, #chat2, #chat3, #chat4').prop('checked', false);

$('#chat1, #chat2, #chat3, #chat4').prop('checked', true);
