var obj = {name0: "11", name1: "22", name2: "33"};
for (var key in obj){
console.log(key +':'+ obj[key])
console.log 结果是：
name0:11
name1:22
name2:33
for in 可以用于数组或者对象var obj = {name0: "11", name1: "22", name2: "33"};for (var key in obj){ console.log(key +':'+ obj[key])}console.log 结果是：name0:11name1:22name2:33...
