How to ignore clicks for checkboxes?

Question

I need to attach a function to a checkbox so that clicking it does nothing. How is this possible? I don't want it to be greyed out, I just want to stop it from being togglable.

Answer 1

If you want it to be toggleable, just attach an event listener as follows:

$('#checkboxId').on('click', function(e) {
    e.preventDefault();
    e.stopPropagation();
});

Note: This is the same effect as returning false:

$('#checkboxId').on('click', function(e) {
    return false;
});

Answer 2

Try something like this:

<input type="checkbox" onClick="this.checked=!this.checked" />
