    Hey guys I've 1 question. This code works:
    if(document.form.filed.value.match( /Your text/ig))

    but if I want to add << http://www >> e.g
    if(document.form.filed.value.match( / http://www /ig))

    it doesn't work :( is it because of the 'slash'?
     
    Solved! View solution.

    you need to escape the slashes..
    if(document.form.filed.value.match( / [url]http:\/\/www[\/url] /ig))
    Code (markup):
    if it still doesn't work, escape the regular expression symbols that should be text..
    if(document.form.filed.value.match( / [url]http:\/\/www[\/url] /ig))
    Code (markup):

    yes it will, but it will also valid for invalid url forms..

    you may want to just use this..

    if(document.form.filed.value.match( / http:\/\/[a-z0-9\-\_\.].com /ig))
