[Vuejs]-URL validation using regular Expression vue JS

You need to make multiple changes to make it work:

• There is no need to add + quantifiers in \/\/.
• No need to add \w in [w\d]+. Since you are matching www or w3 something like this so \w is allowed means you are allowing alphanumeric and underscore also.
• Add $ at the end of the regex, match only if it matches completely

var regex = /^(http|https):\/\/[w\d]+\.[\w](\/[\w\d]+)?$/;
const str = "http://www.google";

console.log(regex.test(str));
