Answer 1

Try to use that function:

(function isURL(s) {
    var regexp = /http(s?):\/\/www\.[A-Za-z0-9\.-]{3,}\.[A-Za-z]{3}/;
     return regexp.test(s);
})("https://www.google.com")

Answer 2

Try this one:

 ^(http|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&:/~\+#]*[\w\-\@?^=%&/~\+#])?



var re = /^(http|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&:/~\+#]*[\w\-\@?^=%&/~\+#])?/;

alert(re.test(yourString));
