Javascript怎么把两个数组里的多个对象一对应合并

var obj1 = [{
  "id": 980550455852,
  "model": "XQG70-S1208FW",
  "color": "白",
  "invStatusName": "正品",
  "bactualQty": 10947,
  "brealyQty": 11000,
  "bavailQty": 53
}, {
  "id": 980550566221,
  "model": "XQB70-C3006",
  "color": "灰",
  "invStatusName": "正品",
  "bactualQty": 11,
  "brealyQty": 6,
  "bavailQty": -5
}];

var obj2 = [{
  "price": "6666"
}, {
  "price": "8888"
}];

简洁的代码:

obj1.map((o,i) => { return {...o,...obj2[i]}})

比较好理解的代码:

//es2015实现合并对象函数代码

```javascript
function assign(target, args) {
    if (target === null) return;
    if (Object.assign) {
        return Object.assign(target, args);
    } else {
        var _ = Object(target);
        for (var j = 1; j < arguments.length; j++) {
            var source = arguments[j];
            if (source) {
                for (var key in source) {
                    if (Object.prototype.hasOwnProperty.call(source, key)) {
                        _[key] = source[key];
                    }
                }
            }
        }
        return _;
    }
};

var result = obj1.map(function(o,index){
    return assign(o,obj2[index]);
})

方法2：

obj1.sort((a,b) => { return b.id - a.id });
