experiment one
this experiment prints the contents of the textarea in an alert, and also prints the tagname of the clicked items into the first span tag available....
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("a").click(function(){
var curText= $("#myText").val();
var urlname = curText;
alert(urlname);
});
$("*", document.body).click(function (e) {
e.stopPropagation();
var getthething = $(this).get(0);
$("span:first").text("Clicked on - " + getthething.tagName);
});
});
</script>
</head>
<body>
<a name="namename" id="idname" href="index2.html"> non nummy bong bong</a>
<br><br>
<span class=first></span>

</body>
</html>
assuming im trying to get the countrycode from a url thats like "summerisle?countrycode=SM" and you want to retrieve just the code at the end. you can use jquery along with Regular Expressions
$("a").click(function(){
var curText= $("#element");
var urlname = curText;
alert(this.href.match(/countrycode=(\w\w)/));
});
alternatively you can do the same thing with substrings
$("a").click(function(){
var countryname = this.href;
var countrycode = countryname.substring(countryname.length-2);
alert(countrycode);
});
