            "message": { "email": "email is required " , "fname": "fname is required " , "lname": "lname is required " , "password": "password is required " , "birthDate": "birthDate is required " , "zip": "zip is required "  },
            "boolean": false,
            "eType": 0
    }

我需要在arr1中添加新对象。它应该是这样的..

myArray:{
  id:'',
  arr1:[],
  arr2:[]
}

是的，这应该是结构。香港专业教育学院曾尝试使用array.push，但无法正常工作。

请帮忙。谢谢！

Answer 1

因为Vigneswaran提到它的对象不是数组你可以直接那样做

myArray.arr1={index1:'',index2:''};

Answer 2

myArray不是数组，它是一个Object。如果我理解正确，你可以得到你想要的东西..

var myArray = {
              id:'',
              arr1:{},
              arr2:{}
            };  
console.log(myArray);           
myArray.arr1 = { index1:'', index2:''};
myArray.arr2 = { index1:'', index2:''};
console.log(myArray);

Answer 3

我同意对此的评论。 /* I wont print "*/" I will print as the "*/" is seen as the end of the comment This line prints */ ## This line will also print at x has not been set back to one是一个对象。要访问媒体资源，您必须使用myArray。 myArray.property和arr1是arr2的属性，因此请使用myArray。

Answer 4

var myArray = {
  id:'',
  arr1:[],
  arr2:[]
};
alert(JSON.stringify(myArray));
delete myArray['arr1'];
delete myArray['arr2'];
myArray['arr1'] ={
   index1:'',
   index2:''
  };
myArray['arr2'] = {
   index1:'',
   index2:''
  };
alert(JSON.stringify(myArray));
