jQuery Disable Onclick Event

Simple jQuery code snippets to stop input clearing on click by disabling the onclick event associated with a button. This is just down and dirty code sorry there is no proper examples.

$('.del').click(function(){
   onclick = $(this).attr('onclick');
   $(this).attr('onclick','');
   showConfirm(onclick);
        return false;
});

$('input').click(function(){
    console.log("clicked");
    onclick = $(this).attr('onclick');
    $(this).attr('onclick','');
    showConfirm(onclick);
    return false;
});

$('input').each(function () {
this.onclick = undefined;
});
$('.foo').removeAttr('onclick').click(function(){
// Do something
});
var original_onclick = $('.del').attr('onclick');
$('.del').removeAttr('onclick').click(function(){
showConfirm(original_onclick);
});
