"'localStorage' Is Null Or Not An Object" Error In IE8

I have this string which i'm trying to store and get to localStorage, and retrieve from it so it could show. Here's my code: var datas = new Array; if (navigator.appName !== 'Micro

Solution 1:

As per my understanding IE8 give storage to only valid domains. Try placing your example in some Web-server it should resolve the issue.

I faced the same issue when I tested it as an individual file but when i placed it in a server(Tomcat in my case) it just worked fine.

Solution 2:

Check if you are actually in IE 8 mode - as opposed to quirks or IE 7 mode. Fastest way to do this is hit F12 to bring up the dev tools, and the browser mode is listed on the upper right of that tab.

Solution 3:

I would give using window.localStorage as shot. See Introduction to Web Storage for IE

Solution 4:

Can you open the developer tools in IE and check that typeof json. stringify and json.parse are functions and also localstorage. I am not sure whether native JSON exist on IE.

Also why are you setting the object inside the loop, shouldnt it be outside it?

[Edit] Added this fiddle for your code jsfiddle.net/yrhdN/2 and everything seems to work fine. I have tested in IE9 under IE8 compatibility mode)

[Edit] One more thing about this code, it seems innerHtml in showStuff() doesn't work with a paragraph. Changing the html from p to div and using innerText makes things a little better:

<div id="stuff">
</div>


function showStuff(){
    var storedPlays    = JSON.parse(localStorage.getItem('datas'));
    document.getElementById("stuff").innerText = storedPlays;
}

This seems to happen only in IE. Here is an updated fiddle: http://jsfiddle.net/yrhdN/7/

Solution 5:

Try this also if you do not wish any local server application to shoot the webpage.

• Look for the code in your script : window['localStorage'] !== null
• change it to : window['localStorage'] != null

It worked in my case.
