JS Regex url validation

rated 0 times [ 15] [ 5] / answers: 1 / hits: 86276 / 9 Years ago, sun, june 21, 2015, 12:00:00

I tried to validate url with or without http No matter what i did the function return false.
I checked my regex string in this site:
http://regexr.com/
And its seen as i expect.

    function isUrlValid(userInput) {

        var regexQuery = /(http(s)?://.)?(www.)?[-a-zA-Z0-9@:%._+~#=]{2,256}.[a-z]{2,6}b([-a-zA-Z0-9@:%_+.~#?&//=]*)/;

        var url = new RegExp(regexQuery,g);

        if (url.test(userInput)) {

            alert('Great, you entered an E-Mail-address');

            return true;

        }

        return false;

    }

I fix the problem by change the .test to .match and leave the regex as is.

I change the function to Match + make a change here with the slashes and its work: (http(s)?://.)

The fixed function:

function isUrlValid(userInput) {

    var res = userInput.match(/(http(s)?://.)?(www.)?[-a-zA-Z0-9@:%._+~#=]{2,256}.[a-z]{2,6}b([-a-zA-Z0-9@:%_+.~#?&//=]*)/g);

    if(res == null)

        return false;

    else

        return true;

}
