如何使用javascript合并对象？ [英] How to merge objects using javascript?

问题描述

我有以下

$scope.Marketing = [{
    'ProductId':1,
    'ProductName':'Product 1',
    'ProductDescription':'Product Description 1'
  },
  {
    'ProductId':2,
    'ProductName':'Product 2',
    'ProductDescription':'Product Description 2'
  }];

  $scope.Finance=[{
    'ProductId':1,
    'Price':'$200.00'
  },
  {
    'ProductId':2,
    'Price':'$100.00'
  }];

  $scope.Inventory=[{
    'ProductId':1,
    'StockinHand:':26
  },
  {
    'ProductId':2,
    'StockinHand':40
  }];

我希望输出

我的合并功能在这里

$scope.tempresult=merge($scope.Marketing,$scope.Finance);  
 $scope.result=merge($scope.tempresult,$scope.Inventory);

function merge(obj1,obj2){ // Our merge function
var result = {}; // return result
for(var i in obj1){      // for every property in obj1 
    if((i in obj2) && (typeof obj1[i] === "object") && (i !== null)){
        result[i] = merge(obj1[i],obj2[i]); // if it's an object, merge   
    }else{
       result[i] = obj1[i]; // add it to result
    }
}
for(i in obj2){ // add the remaining properties from object 2
    if(i in result){ //conflict
        continue;
    }
    result[i] = obj2[i];
}

return result;

}

但输出为

缺少第一手股票的价值。请帮助

The value for first Stock In Hand is missing. Please help

我犯的错误是什么？

如果有人帮助我弄清楚我在功能上做了什么错，我会更高兴。我太累了。提前致谢

I would be more glad if somebody helps me in figuring out what wrong I am doing in my function. I am too tired. Thanks in advance

推荐答案

您可以使用Jquery.extend属性，看一下plnkr代码

you could use Jquery.extend property, have a look at the plnkr code

$scope.result=merge($scope.Marketing, $scope.Finance,$scope.Inventory);

function merge(obj1,obj2, obj3){
    return $.extend(true, obj1,obj2,obj3)
}
};
