使用jQuery单击父级时触发提交按钮的单击

Question

I have a submit button wrapped in a div. I want to trigger a click event on the submit button when the div is clicked. The problem is, this click event bubbles up and causes a stack overflow/infinite loop. When I try to stop propagation of the child click event, the issue is not resolved.

HTML:

<div class="container">
    <input type="submit" value="OK">
</div>

jQuery:

$('.container').click(function () {
    var input = $(this).find('input');
    input.trigger('click');
    input.click(function(event) {
        event.stopPropagation();
    });
});

This still causes the stack overflow error. So does returning false:

$('.container').click(function () {
    var input = $(this).find('input');
    input.trigger('click');
    return false;
});

Help appreciated!

Answer 1

Don't bind button click event inside container click one. It should be this way

$('.container').click(function() {
    var input = $(this).find('input');
    input.trigger('click');
});

$('input').click(function(e) {
    e.stopPropagation();
    alert('button clicked');
});

The problem with your code is that container click triggers inner button click before its respective click handler is even registered, so it have no chance to stop event bubbling.
