How to Loop through local storage to match login inputs

Question

I am making a small login system using local storage. In my js I need some way to loop through the local storage to check if there is a match between the input form and json (username, password) in local storage.

Can I use a normal for loop ? jQuery .each?

Use Key to iterate in local db

for (var i = 0; i < localStorage.length; i++){
    console.log(localStorage.getItem(localStorage.key(i)));
}

and for keys :

for (var key in localStorage){
   console.log(key)
}

`$('body').append()`? Use a `console.log()`. – Cerbrus Feb 19 '14 at 12:01
Or key = localStorage.key(i); alert(localStorage.getItem(key)); – Bhupendra Shukla Feb 19 '14 at 12:05

my localStorage for users is call 'users', so: for (var i = 0; i < localStorage.users.length; i++) ? – Mac Luc Feb 19 '14 at 12:06
and i dont need to .parse the storage before doing the for loop? – Mac Luc Feb 19 '14 at 12:16
