Checkbox inside an anchor click behavior

Question

Consider following snippet:

Answer 1

here's a modified script

var checkbox = $('');
var a = $('#a');
a.unbind("click").click(function(e) {
    e.preventDefault();
    checkbox.attr('checked', !checkbox.attr('checked'));
});
checkbox.prependTo(a);
checkbox.click(function(e) {
    e.stopPropagation();
    // do something useful 
});

i unbind the click event on the and rebind it with a event to check/uncheck the checkbox and also prevent the default.
