I want an event to fire client side when a checkbox is checked / unchecked:
$('.checkbox').click(function() { if ($(this).is(':checked')) { // Do stuff } }); Basically I want it to happen for every checkbox on the page. Is this method of firing on the click and checking the state ok?
I'm thinking there must be a cleaner jQuery way. Anyone know a solution?

Checking if a checkbox is checked First, select the checkbox using a DOM method such as getElementById() or querySelector() . Then, access the checked property of the checkbox element. If its checked property is true , then the checkbox is checked; otherwise, it is not.
prop() and is() method are the two way by which we can check whether a checkbox is checked in jQuery or not. prop(): This method provides an simple way to track down the status of checkboxes. It works well in every condition because every checkbox has checked property which specifies its checked or unchecked status.
change() updates the textbox value with the checkbox status. I use . click() to confirm the action on uncheck. If the user selects cancel, the checkmark is restored but .
Bind to the change event instead of click. However, you will probably still need to check whether or not the checkbox is checked:
$(".checkbox").change(function() { if(this.checked) { //Do stuff } }); The main benefit of binding to the Redacted in commentschange event over the click event is that not all clicks on a checkbox will cause it to change state. If you only want to capture events that cause the checkbox to change state, you want the aptly-named change event.
Also note that I've used this.checked instead of wrapping the element in a jQuery object and using jQuery methods, simply because it's shorter and faster to access the property of the DOM element directly.
Edit (see comments)
To get all checkboxes you have a couple of options. You can use the :checkbox pseudo-selector:
$(":checkbox") Or you could use an attribute equals selector:
$("input[type='checkbox']") If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
