javascript - 需要回调在nodejs中返回多个值

Question

我想在我的回调函数中有多个值

myfunction(i,function(err,result){
  console.log(JSON.parse(JSON.strigify(result)));   
 ****//i need value here..****


});

function myfunction(i,callback) {
/* my some stuff */
var callBackString= new Array();
                        callBackString['value1']=value1;
                        callBackString['value2']= value2;
                        callBackString['value3']= value3;
                        callback(null,callBackString);

};

我正在将 callBackString 作为数组返回..,

谁能告诉我怎么做

谢谢

您应该改用对象:

function myfunction(i, callback) {
  var callBackString = {};
  callBackString.value1 = value1;
  callBackString.value2 = value2;
  callBackString.value3 = value3;
  callback(null, callBackString);
}

然后是接收端:

myfunction(i, function(err, result) {
  var value1 = result.value1;
  var value2 = result.value2;
  var value3 = result.value3;

  console.log(JSON.parse(JSON.strigify(result)));   
});
