Javascript to Remove Html Code

Is there a javascript that can remove html code from a webpage? I want to remove the first part of some urls so that only part of it is visible.

Instead of showing this:
http://www.example.com/search?=help

I want to show this:
help

Hi,

Can you please clarify what it is you want to do.

What i'm trying to do is get a youtube video to work within a new forum script. I've got the bb code working so that if a user can get the video id from the url, it can play embedded within the forum.

However, everyone seems to accidentally post the entire url (making the video unplayable). I was thinking if there's a way to strip out the first part of the url, the video could still play.

Hi,

This example should do what you want:

<script type="text/javascript">
var url = "http://www.youtube.com/watch?v=AAAAAAAAA";
var searchString = "?v=";
alert(url.substring(url.indexOf(searchString)+searchString.length));
</script>

I've just been working on a similar solution to little G and came up with this:


function stripURL(url)
{
if(url.indexOf('=')!= -1)
{
strip_start = url.lastIndexOf('=');
strip_end = url.length;
return url.substring(strip_start, strip_end);
}
else return url;
}

returns everything after the last '=' in the url (if there is one present).

I took out the last line from your script. Was it there just as an alert?

My last post didn't make much sense. This is what I'm trying to get to work.

I need to get this url:
[youtube.com...]

To change to this:
[youtube.com...]

Using little g's code:
---------------------------------


<head>
<script type="text/javascript">
var url = "http://www.youtube.com/watch?v=AAAAAAAAA";
var searchString = "?v=";
alert(url.substring(url.indexOf(searchString)+searchString.length));
</script> 
</head>
<body>
<object width="425" height="350"><param name="movie" value="http://www.youtube.com/v/ovJeGPeh43c"></param><embed src="http://www.youtube.com/v/http://www.youtube.com/watch?v=ovJeGPeh43c" type="application/x-shockwave-flash" width="425" height="350"></embed></object>
</body>

---------------------------------
I don't know much javascript, but the above code I have isn't working.

Hi,

try this:


<body>
<script type="text/javascript">
  var url = "http://www.youtube.com/v/http://www.youtube.com/watch?v=ovJeGPeh43c";
  var searchString = "?v=";
  var out = "<object width=\"425\" height=\"350\"><param name=\"movie\" value=\"http://www.youtube.com/v/";
  out += url.substring(url.indexOf(searchString)+searchString.length);
  out += "\"></param><embed src=\"http://www.youtube.com/v/";
  out += url.substring(url.indexOf(searchString)+searchString.length);
  out += "\"type=\"application/x-shockwave-flash\" width=\"425\" height=\"350\"></embed></object>";
  document.write(out);
</script>
</body>

For some reason, in internet explorer 7, URL tags are sometimes being added automatically. Is there a way to identify whether or not they were added (and to strip them out if they were)?

This is an example of the problem that is happening:

<body> 
<script type="text/javascript"> 
var url = "http://www.youtube.com/v/[url ]http://www.youtube.com/watch?v=ovJeGPeh43c[ /url]"; 
var searchString = "?v="; 
var out = "<object width=\"425\" height=\"350\"><param name=\"movie\" value=\"http://www.youtube.com/v/"; 
out += url.substring(url.indexOf(searchString)+searchString.length); 
out += "\"></param><embed src=\"http://www.youtube.com/v/"; 
out += url.substring(url.indexOf(searchString)+searchString.length); 
out += "\"type=\"application/x-shockwave-flash\" width=\"425\" height=\"350\"></embed></object>"; 
document.write(out); 
</script> 
</body>

Hi,

That url tag problem must be caused by another script you are using, it shouldn't have anthing to do with Internet Explorer 7 specifically.

It seems to happen in my wysiwyg editor. If a url is pasted in it, it gets automatically wrapped in url tags. Seems to only happen in internet explorer 7.

Hi,

You might want to start a new tread about that.
