URL validation for a request form

[Anna L]

Hi,

I have a client requirement to have a request form field "URL". Basically, asking users to enter a URL of the site they manage. Requirement is to validate the URL if it is valid. How would I do that considering I have validation criteria?

Hi Ronald,

You can use a regex to validate url.

var url = g_form.getValue('url_field');

var re = /^(http[s]?:\/\/){0,1}(www\.){0,1}[a-zA-Z0-9\.\-]+\.[a-zA-Z]{2,5}[\.]{0,1}/;
if (!re.test(url)) {
  alert("invalid url");
    return false;
}

PLEASE, DO NOT USE THE ACCEPTED SOLUTION, IT IS NOT WORKING CORRECTLY.

Example: the mentioned RegEx validates to true using this URL: httpsss.safdgoiuhasdg

httpsss.safdgoiuhasdg is not a valid URL.
