How to do an action when a checkbox is checked with jQuery?

checkbox, jquery

Solution

What you are looking for is called an Event. JQuery provides simple event binding methods like so

$("#home").click(function() {
    // this function will get executed every time the #home element is clicked (or tab-spacebar changed)
    if($(this).is(":checked")) // "this" refers to the element that fired the event
    {
        alert('home is checked');
    }
});

Problem

I want to do an action when a user checks a checkbox, but I can't get it to work, what am I doing wrong? So basically, a user goes to my page, ticks the box, then the alert pops up. ``` if($("#home").is(":checked")) { alert(''); } ```
