Sorry for the delay I was very busy...
replace className by class :

So use : $('[class^="hello"]')
or : $('*[class^="hello"]')

$(document).ready(function() {
 $('[class^="hello"]').each(function(index) {
  alert($(this).attr('class'));
 });
});

</script>
</head>
<body>

<h1 class="helloH">Heading</h1>
<div class="hello1">1</div>
<div class="hello2">2</div>
<div class="hello3">3</div>
<p class="nomatch">This should not be included</p>
<p class="helloP">ABC</p>
<p class="helloXYZ">XYZ</p>
