// summary:
|
|
// Check if a parameter is ready, and if not,
|
|
// "do later". doLater will ping the parameter
|
|
// until it evaluates to something (truthy).
|
|
// It thens calls the caller with original
|
|
// arguments, using the supplied context or
|
|
// window.
|
|
// description:
|
|
// dojox.timing.doLater(conditional) is testing if the call
|
|
// should be done later. So it returns
|
|
// true if the param is false.
|
|
// arguments:
|
|
// conditional: anything
|
|
// Can be a property that eventually gets set, or
|
|
// an expression, method... anything that can be
|
|
// evaluated.
|
|
// context: Object
|
|
// The namespace where the call originated.
|
|
// Defaults to global and anonymous functions
|
|
// interval: Number
|
|
// Poll time to check conditional in Milliseconds
|
|
// example:
|
|
// | setTimeout(function(){
|
|
// | if(dojox.timing.doLater(app.ready)){return;}
|
|
// | console.log("Code is ready! anonymous.function SUCCESS")
|
|
