推荐答案
您还可以使用 $ .each 函数:
var obj = { one:1, two:2, three:3, four:4, five:5 };
$.each(obj, function(key, value) {
//..
});
如果您在for...in 中查找问题(如果是Object).原型已扩展:
If you go for the for...in statement way, I would recommend you to check if the property resides directly on the object being iterated, because you could have some issues, if the Object.prototype is extended:
for(var key in obj) {
if (obj.hasOwnProperty(key)){
// value = obj[key];
}
}
