regex for url validation using jquery

Question

I need to validate the url using regex. The valid formats that should be accepted are as follows:

users.kathir.com www.kathir.com

I am currently using the following regex:

^[a-z0-9-]+(\.[a-z0-9-])+(.[a-z])

But it accepts www.google as the valid one, but it should accept either google.com or www.google.com only. Please suggest

If you're only interested in capturing top-level domains that end in .com / .edu / etc., then you can literally place those characters to be validated in the last section. ....(com|edu) rather than the character class .[a-z]. You should update your question to be very specific about what you want to validate rather than four examples only showing one example of an invalid URL — veeTrain

I use this, works pretty well:

function checkUrl(url){ return url.match(/(http|ftp|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&amp;:/~\+#]*[\w\-\@?^=%&amp;/~\+#])?/); }

Hope that helps :)

The answer provided by user will also validate those regex in which there is no .com|edu|org etc at the end to make it more appropriate I have modify the regex which works fine for me and also want to share with you

var pattern = /^(http|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&amp;:/~\+#]*[\w\-\@?^=%&amp;/~\+#])+(.[a-z])?/; var regex = new RegExp(pattern); var website_url = $("#website_url").val();// url of the website if (website_url.match(regex)) { return true } else { return false; }
