为什么这个事件监听器不起作用？

Question

    $('input[type=checkbox]').unbind().click(function(e){
        $(this).attr('checked', true)
        return false;
    });

I NEED to return false because I have an event on its parent and I don't want to trigger that. It just WON'T check that checkbox.

Answer 1

$('input[type=checkbox]').unbind().click(function(e){
    e.stopPropagation();
});

Edit: I'm not sure what you need .unbind() for, but you should beware that that is canceling any other events you've put on those checkboxes.

Answer 2

您在jQuery选择器的末尾缺少一个]
