Regular Expressions - Javascript

Hi guys,

I have incorporated Snap Shots into my blog the other day but wish to make it only work for links that are pointing to wikipedia.org.

In the FAQ page they tell me to use

Expand|Select|Wrap|Line Numbers

 
<script type="text/javascript">

//<[CDATA[

var links = document.getElementsByTagName('a');

for (var l = 0; l < links.length; l++) {

    if(links[l].href.match(/^http:\/\/www\.example\.com/)){

        links[l].className += " snap_shots";

    }

}

//]]>

</script>

But replacing example with wikipedia.org does nothing.

I have come up with this on

Expand|Select|Wrap|Line Numbers

 
<script type="text/javascript">

<![CDATA[

var links = document.getElementsByTagName('a');

for (var l = 0; l < links.length; l++) {

    if(links[l].href.match(/^http:\/\/en\.wikipedia\.org\/wiki\//)){

        links[l].className += " snap_shots";

    }

}

]]>

</script>

But it still doesn't work for just wikipedia.org websites.

Any help?

Thank you,

hi ...

the following returns true:

Expand|Select|Wrap|Line Numbers

 
// i removed the last slash that is not needed

var re = /^http:\/\/en\.wikipedia\.org\/wiki/;
 
// this returns true

re.test('http://en.wikipedia.org/wiki/');
 
// this returns true too

re.test('http://en.wikipedia.org/wiki');

so your code should work ... and so there must be an other problem ... try the following example ... it prooves that it should work

[HTML]
<html>
<head>
<style type="text/css">
.test1 {
color: red;
}

.test2 {
font-weight: bold;
}
</style>
</head>
<body>
<a href="http://en.wikipedia.org/wiki/" class="test1">wiki</a>
<script>
var l = document.getElementsByTagName('a');
alert(l[0].href);

if (l[0].href.match(/^http:\/\/en\.wikipedia\.org\/wiki\//)) {
l[0].className += " test2";
}
</script>
</body>
</html>
[/HTML]
kind regards ...

ps: check that you have the snap_shots css-class included ... or may be there are conflicting css-rules etc. post back when you discover the problem and need more help
