stack如果属性为原始类型，则我将存储一个字符串，然后将其输出：
function iterate(obj, stack) { for (var property in obj) { if (obj.hasOwnProperty(property)) { if (typeof obj[property] == "object") { iterate(obj[property], stack + '.' + property); } else { console.log(property + " " + obj[property]); $('#output').append($("<div/>").text(stack + '.' + property)) } } } }iterate(object, '')
