Wie mache ich eine asynchrone Wrap-Funktion für die asynchrone Funktion?

Question

Ich habe 'func1', die async 'func2' hüllt wie:

func1 = function(arg1) { 
    func2 (arg1, function(result) { 
     // parse and return some parts of 'result' 
    }, function(error) { 
     alert (error.message); 
    }) 
} 

Wie async zu 'func1' machen (für externen Code).

Answer 1

function wrapper(callback) {//async callback is the standard for most libs func1(arg1);//call that original func1 you defined. callback(); //first arg is error, second is result (you don't have any result so it is empty) }
