I need Javascript code to extract links?

Give me a javascript code that can extract links on a web page. Further the script should write those links to a blank div of the same page (when a button is clicked). I need help.

You didn't say what exactly you wanted to write, but you should be able to get anything you need from the following example.

<head>
<script type="text/javascript">
function showLinks() {
// get all anchors in page
var links = document.getElementsByTagName( 'A' );
// how many anchors
var last = links.length;
// initialize output for concatenation
var list = '';
// for each anchor...
for (var i = 0; i < last; i++) {
// concatenate info for current anchor
list += 'link ' + (i + 1) + ': ' +
' href=' + links[i].href +
' - text=' + links[i].innerHTML + '<br>';
}
// get reference to out display area
var linksList = document.getElementById( 'linksList' );
// write output to page
linksList.innerHTML = list;
}
</script>
</head>
<body>
<form>
<input type="button"
value="show links"
onclick="showLinks()" />
</form>
<p>

<a href = "http://www.google.com"> Google</a> <br>
<a href = "http://www.wikipedia.com"> Wikipedia </a><br>
<a href = "http://www.yahoo.com"> Yahoo! </a><br>
</p>

<div id="linksList"></div>
</body>
</html>

I used the deprecated form of the break tag to prevent Y!A from replacing it with actual breaks.
