where going wrong?

your script not proper, need pass function parameter ready()

$(document).ready(function() {     $("#rolemanagement").submit(function() {         alert("hi");         var selected = new array();         $('#checkboxes input:checked').each(function() {             selected.push($(this).attr('name'));         });         $.each(selected, function(key, value) {             alert(key + ": " + value);         });      }) });
