Title
Body
Suppose I load some Flash movie that I know at some point in the future will call window.flashReady and will set window.flashReadyTriggered = true . Now I have a block of code that I want to have executed when the Flash is ready. I want it to execute it immediately if window.flashReady has already been called and I want to put it as the callback in window.flashReady if it has not yet been called. The naive approach is this: if(window.flashReadyTriggered) { block(); } else { window.flashReady = block; } So the concern I have based on this is that the expression in the if condition is evaluated to false , but then before block() can be executed, window.flashReady is triggered by the external Flash. Consequently, block is never called. Is there a better design pattern to accomplish the higher level goal I'm going for (e.g., manually calling the flashReady callback)? If not, am I safe, or are there other things I should do?
