actionscript 2.0 基础知识回顾(创建对象)

1.创建简单对象
var secondObj:Object = {firstVar:"hello world", secondVar:28, thirdVar:new Date(1980, 0, 1)};
var i:String;
for (i in secondObj) {
trace(i + ": " + secondObj[i]);
}

2.使用数组创建对象
var usersArr:Array = new Array();
usersArr.push({firstname:"George"});
usersArr.push({firstname:"John"});
usersArr.push({firstname:"Thomas"});

var i:Number;
for (i = 0; i < usersArr.length; i++) {
trace(usersArr[i].firstname); // George, John, Thomas
}

__________________________________
var myObj:Object = {var1:"One", var2:"Two", var3:18, var4:1987};
var i:String;
for (i in myObj) {
trace(i + ": " + myObj[i]);
}
//输出以下结果：
/*
var1: One
var2: Two
var3: 18
var4: 1987
*/
3.转换对象
var firstNum:String = "17";
var secondNum:String = "29";
trace(firstNum + secondNum); // 1729
trace(Number(firstNum) + Number(secondNum)); // 46
