async callback source for lazy loading

[davazp]

lazyLoad function can set data.result to any kind of source. However, only ajax source and promises can get data asynchronously. But it is restricted to ajax and jquery

It would be useful if there was support for a general async callback

function(callback){
   callback(source);
   return true;
}

Because callbacks now are synchronous, so it would break compatibility. A special value could be returned to specify it is asynchronous, or even wrapping the function maybe.

My use case is, I am using fancytree from Angular and I need to use $http to fetch my data instead of jquery. But I am sure it would be useful for other uses too.

You can use promises in very general ways, I think. Simply resolve when the data arrives.
But maybe I misunderstood your request, since I am not familiar with Angular.
Is $http async?
Can you give some code samples?

You are right, it is not needed.

The tutorial says:

source may be a deferred promise as returned by $.ajax() or $.getJSON().

My problem was that I thought it did not accept general jquery promises, but only the result of $.ajax or $.getJSON. Perhaps it could be clarified in the documentation.

Therefore I can create a jquery promise, use Angular to get the data and then resolve the promise with the result.

Thank you.
