What I’m trying to do: Create my own storage API on top of localStorage

  • 0

What I’m trying to do:

Create my own storage API on top of localStorage so it is easier to use in my own code.

Why?

So it has an API for my purposes and can be extended later.

System:

Chrome Version: Version 22.0.1229.94 m

JSFiddle: http://jsfiddle.net/ttback/kr88W/

Error

The fiddle will trigger an error in Console:

TypeError: Property ‘localStorageSave’ of object # is not a function

This works in IE 8 and Firefox 16.0.1, so I am wondering if I’m missing something or is it a Chrome bug.

Code:

<html>
<head>
<title>JS function not working in Chrome</title>
<script type="text/javascript">
var localStorage = localStorage || {};
localStorage.localStorageSave = function(){
    alert("SAVE");
};
localStorage.localStorageSave();
</script>
</head>
<body>

    
</body>

</html>​

    When you do 

    localStorage.localStorageSave = function(){
    alert("SAVE");
};

    you’re doing the same as 

    localStorage["localStorageSave"] = function(){
    alert("SAVE");
};

    or

    localStorage.setItem("localStorageSave", (function(){
    alert("SAVE");
}).toString());

    You’re in fact not saving a function in localStorage, because localStorage saves only strings.

    You can check it with 

    console.log(typeof(localStorage.localStorageSave));

    You get "string". This isn’t a function and is normal.
