XMLHttpRequest predefined values for LOADING, DONE, etc. appear undefined under Ripple

boyanov · ‎02-12-2010

I am using XMLHttpRequest to call a REST services.

When testing is under Mozilla and Chrome everything works just fine.

Although, when I enabled the Ripple under Chrome it stopped working. After some debugging I found out that in the switch/case statement, where I do something like ...

switch (this.readyState) {
 case XMLHttpRequest.DONE: ... some code here ... break;
}

... the "case" does not get fired.

Closer examination determined that all the values XMLHttpRequest.* are undefined so that is the reason my code stopped working.

Q: Why XMLHttpRequest readyState values, otherwise well defined, become undefined under Ripple?

Are there any solutions for that issue, other than using plain numbers like 1, 2, 3, 4 or defining the values myself.

Here is a testing script that I've used to determine the poblem above ...

<html>
<body>
<div id="log"></div>
<script type="text/javascript">
document.getElementById("log").innerHTML = "XMLHttpRequest.DONE=" + XMLHttpRequest.DONE + "<br />\n";
</script>
</body>
</html>

Under Chrome it gives XMLHttpRequest.DONE=4

Under Ripple it gives XMLHttpRequest.DONE=undefined

Are you using the latest version of Ripple - the Chrome extension beta? I just tested and the value is there.

Here are different environments I use to test:

(1)

Google Chrome 19.0.1084.46 m

Ripple Mobile Environment Emulator (Beta) 0.9.3

Settings: Platform=WebWorks, Device=Torch

Test: fail ... XMLHttpRequest.DONE=undefined

(2)

Ripple 0.9.0.16

Ripple Mobile Emulator (v0.9.1)
Ripple UI (v0.9.2)
Ripple Framework (v0.9.1)
Ripple Build & Deploy (v0.9.0)

Settings: Platform=WebWorks, Device=Torch

Test: fail .... XMLHttpRequest.DONE=undefined

Please try with 0.9.4 which is what I'm running.

After installing the Ripple Emulator (Beta) 0.9.5 the script passes the test.

Looks like you have to download the Ripple from https://developer.blackberry.com/html5/downloads/ripple and then manually install the Chrome extension instead of just updating the extension from the menu.

Thanks.
