Mojo SDK - set a timer

I'm messing around with building an application for the Palm Pre.

I have a simple question: How can I set up a timer for some code to get run after a certain amount of time has passed?

I tried using the regular old javascript setTimeout, but it doesn't seem to work.

Here is what I've tried:

setTimeout(this.someFunction, 3000);
setTimeout('this.someFunction()', 3000);

Neither one seems to work. How can I accomplish this?

Solution

  • Turns out that the prototype javascript framework is used by Mojo.

    I was able to solve this issue by using:

    this.someFunction.delay(seconds, [functionArgs,]);

    One thing that tripped me up was that the delay method changed the value of this, so the delayed function must not expect that this will be the same as if you had simply invoked it directly.
