Question

I will show the problem with a example.

There is some text in the textbox such here:

Hi! this is a example [lnk]text[/lnk]

When i push the submit button and publish this text, the word in the [lnk] and [/lnk] tags must be a link like this http://www.mysite.com?link=text.

How do I make it easily with javascript or jquery?

Note: I’m not so good about javascript.

This will do the javascript for you – not sure if you need to do anything special for asp.net

<form onsubmit='return doLinks(this.elements['links']);'> <textarea name='links' rows='20' cols='80'></textarea> <input type='submit'> </form>  <script type='text/javascript'>  function doLinks(elm) {     var matches = elm.value.match(/\[link\](.*?)\[\/link\]/gi);     for (var i = 0; i < matches.length; i++)     {         var url = 'http://www.mysite.com/?link=' + encodeURIComponent(matches[i].substring(6, matches[i].length - 7));         elm.value = elm.value.replace(matches[i], url);     }      return true; }  </script>
