string could be anything @username is the link in multi-line string.. we need to link the @username anywhere in the url.. just like twitter
$text = preg_replace('!(^|\W)@(([a-z0-9]+(\.?[-_a-z0-9]+)*)+)!', '\\1<a href="http://$2.'.site::$domain_only.'">@$2</a>', $text);
its my php version.. how can i convert it or use it same with javascript.
You can convert the code nearly one-on-one:
text = text.replace(/@+([a-z0-9]+(\.?[-_a-z0-9]+)*){2,255}/g, "<a href='http://$0.".site::$domain_only."'/>$0</a>");
text = text.replace("='http://@", "='http://");
And you will need to replace site::$domain_only with its value, e.g.:
var domain_only = '…';
text = text.replace(/@+([a-z0-9]+(\.?[-_a-z0-9]+)*){2,255}/g, "<a href='http://$0."+domain_only+"'/>$0</a>");
text = text.replace("='http://@", "='http://");
But I would rather use this regular expression:
/@+((?:[a-z0-9]+(?:\.?[-_a-z0-9]+)*){2,255})/g
Then you can use the match of the first group directly and don’t need to remove the @ afterwards:
var domain_only = '…';
text = text.replace(/@+((?:[a-z0-9]+(?:\.?[-_a-z0-9]+)*){2,255})/g, "<a href='http://$1."+domain_only+"'/>$1</a>");
Also you can add desired methods to JavaScript String object, like
String.prototype.linkuser=function(){
return this.replace(/[@]+[A-Za-z0-9-_]+/g,function(u){
return u.link('http://'+u.slice(1).toLowerCase()+'.example.com/');
});
};
And then just use it like
// var username = "RT @some0ne this isn't a @twitterUsername";
username.linkuser(); // RT <a href="http://some0ne.example.com/">@some0ne</a> this isn't a <a href="http://twitterUsername.example.com/">@twitterUsername</a>
