AsyncResult.asyncContext property

Gets the user-defined item passed to the optional asyncContext parameter of the invoked method in the same state as it was passed in.

var myContext = asynchResult.asyncContext;

Return Value

Returns the user-defined item (which can be of any JavaScript type: String, Number, Boolean, Object, Array, Null, or Undefined) passed to the optional asyncContext parameter of the invoked method. Returns Undefined, if you didn't pass anything to the asyncContext parameter.

Example

function getDataWithContext() {
    var format = "Your data: ";
    Office.context.document.getSelectedDataAsync(Office.CoercionType.Text, { asyncContext: format }, showDataWithContext);
}

 function showDataWithContext(asyncResult) {
    write(asyncResult.asyncContext + asyncResult.value);
}
// Function that writes to a div with id='message' on the page.
function write(message){
    document.getElementById('message').innerText += message; 
}
