Find text in string and replace with another in JavaScript

Question

My html:

<span data-sample="http://mysite.com"></span>

My JS:

 var objLink = $(this).attr('data-sample');

Hence my objLink == "http://mysite.com"

How can I add "www" and make the objLink == "http://www.mysite.com"?

Not sure this is the answer you are looking for, but you can use .replace() to do this.

objLink = objLink.replace("http://", "http://www.");

And if you want to apply it back to the span, use $(this).attr('data-sample', objLink);

If you satisfied with the answer you will need to accept it. Please read the FAQ

Or .replace("://", "://www.") if you want to allow for potential https links. Maybe add a condition to only do the replace if the url doesn't already have "www" in it...
