How can I get parent id by onclick on a child in js? [duplicate]

Answer 1

One way would be to assign it a class and then just use jQuery to get the id such as this:

$('.check-id').on('click', function(){
    alert($(this).parent().attr('id'));
});

Your div would look like this:

Click

With the above approach you can have many buttons and divs and this would work. You just have to make sure to assign a check-id class to the button.
