Check if checkbox is checked

Question

Why does the following code not work?

Example: http://jsfiddle.net/ZZe5X/18/

$('.submit').submit(function () {
    e.preventDefault()
    if ($('input[type="checkbox"]').is(':checked')) {
        alert('ok')
    } else {
        alert('no')
    }
})

Answer 1

Okey:

1. you are missing the event: $('.submit').submit(function () { should be $('.submit').submit(function (e) {
2. The button is missing a type="submit" and it should be inside the form element.
3. The Form element is missing the class submit

this should work: http://jsfiddle.net/voigtan/ZZe5X/26/

Answer 3

You don't have a submit button in a form with the class submit, so your submit event handler never executes. Add class="submit" to your form tag and change <button>Click me</button> to <input type="submit" value="Click me" /> and move it to before your </form> tag.

Answer 4

Please try this.

   $('.submit').submit(function () {

        if ($('input[type="checkbox"]').is(':checked')) {
            alert('ok');
        } else {
            alert('no');
        }
      return false;
    })

Answer 5

1. You didn't have a submit class
2. You had .submit() set on a button, it needs to be .click
3. You weren't iterating through each checked box, which is what I assume you wanted to be doing.
