/(ftp|https?)://[^ \"]+$/

This is from the ref: Regular expression for URL validation (in JavaScript)

This

Answer 1

Try this

function is_valid_url(url)
{
     return url.match(/^(ht|f)tps?:\/\/[a-z0-9-\.]+\.[a-z]{2,4}\/?([^\s<>\#%"\,\{\}\\|\\\^\[\]`]+)?$/);
}

Call the is_valid_url(YOUR_WEBSITE_URL) function everywhere which you want to website validate.

Try This ..

<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
