Question

I need to write a method that takes a String and parses it for links (a href). If it finds a link it should add target=”_blank” to the link, if it is not already there.

Example:
The Inputstring “

 <a href="www.google.com">Google</a> and <a href="www.yahoo.com"> target="_blank">Yahoo</a> are search engines

… should result in the output String

<a href="www.google.com" target="_blank">Google</a> and <a href="www.yahoo.com" target="_blank">Yahoo</a> are search engines

Any idea how to realize this?

Not very difficult with plain js.

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

for(var i=0; i<len; i++)
{
   links[i].target = "_blank";
}
