Question

I think the question title seems to explain eveything.
I want to detect whether a string is in URL format or not using javascript.

Any help appreciated.

Answer 1

Try this-

function isUrl(s) {
   var regexp = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/
   return regexp.test(s);
}

usage: if (isUrl(“http://www.page.com“)) alert(“is correct”) else
alert(“not correct”);
