How to redirect with javascript in a conditional?

Question

This is my code:
$('submit').on('click', function (){
var num = document.getElementById('number').value;
if(num !== ' '){
window.location = 'userAuth.htnl';
}
});
But after I type something into the DOM element and submit it doesn't redirect. But if I console log my input in the conditional, I see it on the console.
Please help.

try this:
$('submit').on('click', function (e){
e.preventDefault();
var num = document.getElementById('number').value;
if(num !== ' '){
window.location = 'userAuth.html';
}
});
