URL Redirect Javascript [duplicate]

Question

URL Redirect Javascript? I have am trying to redirect an entered web address with a http:// and prompt until a http:// is found and if it is found it will direct it to the website that is entered.

Heres my code so far:

function enter() {
    var keepGoing = true;
    var email;
    while (keepGoing) {

        keepGoing = false

        email = prompt("Please Enter Website Address");
        // Website Address validation to see if it has http://
        if (email.indexOf('http://') === -1) {
            alert("Not valid Web Address");
            keepGoing = true;
        }

        // if nothing was entered
        else if (email == '') {
            var email = prompt("Please Enter Valid Web Address");
        }
    }
}
