Syntax

MSApp.execAsyncAtPriority(asynchronousCallback, priority, args);

Parameters

asynchronousCallback [in]

Type: function

The callback function to run asynchronously, dispatched at the given priority priority.

priority [in]

Type: DOMString

The contextual priority value at which the asynchronousCallback callback is run. See MSApp Constants.

args [in]

Type: any

An optional series of arguments that are passed to the synchronousCallback callback function (as parameters 1 and on).

Return value

This method does not return a value.

Remarks

The provided asynchronousCallback callback function is executed asynchronously later. asynchronousCallback will be dispatched according to the provided priority. Normal priority is equivalent to the existing setImmediate method. When the callback is run, the current contextual priority is set to the provided priority parameter value for the duration of the callback's execution.

The asynchronousCallback callback parameter can be any function. If arguments are provided after the priority parameter, they will all be passed to the callback function.

Note  Unlike execAtPriority, any object returned by the asynchronousCallback callback function is ignored (and not returned via execAsyncAtPriority).
 

Examples


MSApp.execAsyncAtPriority(function () { // This callback dispatches at the idle level.
  user.getFirstNameAsync().then(function () { // Promise completes at idle level.
    return user.getLastNameAsync();
  }).done(function () { // Promise completes at idle level.
    // USEFUL CODE HERE
  });
}, MSApp.IDLE);
