咖啡-> JavaScript->打字稿

Question

I'm converting coffeescripts to typescript and have trouble with one simple delay type function.

The coffeescript:

ise.utils.delay = (->
  timer = 0
  (callback, ms) ->
    clearTimeout timer
    timer = setTimeout(callback, ms)
)()

The produced javascript:

  ise.utils.delay = (function() {
    var timer;
    timer = 0;
    return function(callback, ms) {
      clearTimeout(timer);
      return timer = setTimeout(callback, ms);
    };
  })();

When I enter the produced js into a typescript file I get a compile error.

I can't figure out what is wrong.

Answer 1

If the above code is all the code you have, then you are missing var ise = { utils: { delay: {}}}

I think what you are actually looking for is modules in TypeScript like below

module ise.utils {
    var timer = 0;
    export function delay(callback, ms) {
        clearTimeout(timer);
        return timer = setTimeout(callback, ms)
    };
}

I ended up using this:

 module ise { export module utils { var timer = 0; export function delay(callback, ms) { clearTimeout(timer); return timer = setTimeout(callback, ms) };
