枚举JavaScript对象的函数_javascript技巧

枚举JavaScript对象的函数：
function iterator(obj) {
for (var property in obj) {
document.writeln("

" + property + " : " + obj[property] + "

一个简单示例(test.js)：
function Employee () {
this.name = "";
this.dept = "general";
}

function Manager() {
this.reports = [];
}
Manager.prototype = new Employee();

function WorkerBee() {
this.projects = [];
}
WorkerBee.prototype = new Employee();

function SalesPerson() {
this.dept = "sales";
this.quota = 100;
}
SalesPerson.prototype = new WorkerBee();

function Engineer() {
this.dept = "engineering";
this.machine = "";
}
Engineer.prototype = new WorkerBee();
Engineer.prototype.specialty = "code";

function iterator(obj) {
for (var property in obj) {
document.writeln("

" + property + " : " + obj[property] + "
