推荐答案

使用角的：

function myAsyncFunction() {
    var deferred = $q.defer();

    //..
    setTimeout(function() {
        deferred.resolve({ message: "resolved!" });
        // or deferred.reject({ message: "something went terribly wrong!!" });
    }, 1000);
    //..

    return deferred.promise;
}

myAsyncFunction()
    .then(function(data){
        // success
        console.log("success", data.message);
    }, function(data) {
        // fail
        console.log("error", data.message);
    }).finally(function() {
        // always
    });
