I've been trying to create an mraid pliant ad, but haven't gotten very far. According to the official documentation, which can be found at this link, the addition of a simple

<script src='mraid.js'></script>

should be sufficient. This, however, doesn't seem to be the case. I copied the following example code to test the existence of the mraid object, but it just stays undefined. The precise FireBug error is:

ReferenceError: mraid is not defined

I'm trying to execute the following (very simple) code:

if(mraid.getState() !='ready'){
console.log("MRAID NOT READY");}

Does anyone have any experience with this problem?

• 1 Your code is wrong, you expect mraig.getState to return 'ready', but this state do not exist. It's a mon error on many MRAID sample codes, indeed when mraid is ready, the mraid.getState return 'default'. – kketch Commented Mar 25, 2013 at 15:03
• Thanks for your ment! :) It isn't the problem here, as John Cappiello mentioned already, but could definitely have been a problem later on :) – danvdende Commented Mar 26, 2013 at 11:10

Yes, it's not quite as simple as that, and the spec isn't entirely clear.

mraid.js is injected by whatever ad platform your being flighted from.

It looks something like this:

App -> Ad SDK -> MRAID Ad

The Ad SDK instantiates a UIWebView and injects mraid.js to be available. Then your script tag above finds it, loads it, and everything else resolves itself from there.

Your options are either:

1. make your own mraid.js for testing purposes that has enough of the spec to be handy /testing
2. spin up a mobile ad server SDK that does the above for you, and then just test against that
3. checkout http://webtester.mraid which will let you avoid some of the above

2 is the most precise. 1 & 3 get you far, but nothing pares to the real thing in app with an actual ad server's sdk handling things.
