js对象合并问题

[katakibb]

var obj1={
"name":"cash",
"age":18,
"hobby":"footer",
"work":"teacher"
};
var obj2={
"name":"cabbin",
"age":25,
"work":"student"
};


只合并两个对象共有的属性，意思就是把obj1的name、age、work属性给obj2，让obj2的这三个属性的值变成obj1的

使用jquery即可 <script src="https://code.jquery.com/jquery-1.11.3.js"></script> <script type="text/javascript"> var obj1={ "name":"cash", "age":18, "hobby":"footer", "work":"teacher" }; var obj2={ "name":"cabbin", "age":25, "work":"student" }; obj1=$.extend(obj1,obj2); alert(obj1.name) alert(obj1.work) </script> 如果不使用jquery也可以自己直接复制 obj1.name = obj2.name obj1.work= obj2.work

    for (var key in obj2){
        if(obj1.hasOwnProperty(key)){
            obj2 = obj1[key];
        }
    }

Object.assign

Object.assign 在此并不合适。它属于合并所有属性，并不能只合并共同属性。

引用 2 楼 xzy21com 的回复:

    for (var key in obj2){
        if(obj1.hasOwnProperty(key)){
            obj2 = obj1[key];
        }
    }
