javascript url split for manually entering url in a form

Question

i am manually entering a url link in a Html form which might be

https://localhost/inc/Pega/Some.pdf or inc/Pega/Some.pdf ,

i need to check whether the url contains any link i.e https

1) if it contains then i have to strip text link to

'inc/Pega/Some.pdf'

It may differ ! it may starts with https://somelink or sometimes from inc/Docs — Mazher, Jul 22 '13 at 09:30

You can use following JavaScript:

var url = "https://localhost/inc/Pega/Some.pdf";
url = url.replace(/^(http[s]*:\/\/[a-zA-Z0-9_]+)*\//,"")

Now explanation: From the begging of string (^) I remove protocol (http or https) then everything between :// and /, which is letters, numbers or underscore. If link will not start with http:// or https:// or / nothing will be changed

and one more thing when i put something https://something.domain.com/inc/Docs/soem.pdf it doesnt work – Mazher Jul 22 '13 at 09:37
@Mazher about something.domain.com/inc/Docs/soem.pdf it will be always dots in server name? Or something.domain.com is static? – Piotr Stapp Jul 22 '13 at 09:43
@Mazher mark it as answer or vote it up instead of writing: thank you – Piotr Stapp Jul 22 '13 at 10:49

You can the required part of url using substring

Live Demo

if(url.indexOf('https:') == 0)
   $('#text1').val(url.substring(url.indexOf('inc/Pega')));

Run this JS function while submitting the form :

function check_URL_Is_Valid(url){
  var regular_exp = new RegExp("^(http|https)://", "i");
  var given_url = url;
  var match = regular_exp.test(given_url);
  if (match){
    alert('URL is valid');
    var sub_url = given_url.match(/^http[s]?:\/\/.*?\/([a-zA-Z-_]+).*$/)[0];
    alert('SubURL='+sub_url);
  }else{
    alert('URL is Invalid');
  }
}

I hope this will fulfill your requirement. Please let me know if you face any problem.
