html5 window.localStorage.getItemItem get keys that start with

Question

How could I use

window.localStorage.getItem();

to specify items in localstarage that start with the string \'QQ\'. In my case the key

Answer 1

I use this:

 var keyIndex = 0;
 var thisKey = window.localStorage.key(keyIndex);

 while(thisKey != '' && thisKey != undefined)
 {
    if (thisKey.substr(0, 2) == 'QQ')
    {
       // do whatever you need to do with thisKey
    }

    keyIndex+= 1;
    thisKey = window.localStorage.key(keyIndex);
 }

But robertc's solution is right too, it's a bit more simple that way. I actually changed my code to do a for loop too.
