javascript遍历对象属性 - 荆棘人

javascript遍历对象属性

var obj={"0":[{"name":"a"}],"1":[{"name":"a1"}],"2":[{"name":"a2"}]};
console.log(Object.keys(obj));
Object.keys(obj).forEach(function(key,item){
    console.log(key);
    console.log(item);
    console.log(obj[key]);
    console.log(obj[key][0].name);
});

 也可以这样遍历

for( e in obj){
    console.log(obj[e][0].name);
}
