在这段 javascript 中发现了哪些元素/概念？
正在闲逛，发现这对某些东西很方便，但如果你必须问我现在到底是什么，我无法告诉你，所以想知道社区是否可以帮助识别元素和概念以下...
var MyStuff = {
STATS: {
SHOTS:0,
TRIES:0,
HIGHESTSCORE:0,
LIVESLOST:0
},
defaultLevel: 0,
players: [
{
name: 'Chuck',
surname: 'Norris',
punchline: 'Chuck Norris can set ants on fire with a magnifying glass, At night.',
dateCreated: '10/03/2011'
},
{
name: 'Mr',
surname: 'T',
punchline: 'I pity the fool who drinks soy milk.',
dateCreated: '10/03/2011'
}
],
startGame: function() {
alert("You shouldn't have come back, " + this.players[0].surname);
alert("" + this.players[1].punchline);
this.STATS.SHOTS = 0;
this.STATS.LIVESLOST = 1000000000000;
var smiles = this.STATS.LIVESLOST;
//TODO - More stuff
}
}
var KaPow = MyStuff;
用法：
KaPow.startGame();
alert("Starting Level: " + KaPow.defaultLevel);
alert("Player 1: " + KaPow.players[0].name + " " + KaPow.players[0].surname);
alert("Player 2: " + KaPow.players[1].name + " " + KaPow.players[1].surname);
alert("Score: " + KaPow.STATS.LIVESLOST);
Was messing around and found this to be handy for some stuff but if ya had to ask me what exactly is what right now, I wouldn't be able to tell you, so was wondering if the community could help identify elements and concepts in the following...
var MyStuff = {
STATS: {
SHOTS:0,
TRIES:0,
HIGHESTSCORE:0,
LIVESLOST:0
},
defaultLevel: 0,
players: [
{
name: 'Chuck',
surname: 'Norris',
punchline: 'Chuck Norris can set ants on fire with a magnifying glass, At night.',
dateCreated: '10/03/2011'
},
{
name: 'Mr',
surname: 'T',
punchline: 'I pity the fool who drinks soy milk.',
dateCreated: '10/03/2011'
}
],
startGame: function() {
alert("You shouldn't have come back, " + this.players[0].surname);
alert("" + this.players[1].punchline);
this.STATS.SHOTS = 0;
this.STATS.LIVESLOST = 1000000000000;
var smiles = this.STATS.LIVESLOST;
//TODO - More stuff
}
}
var KaPow = MyStuff;
Usage:
KaPow.startGame();
alert("Starting Level: " + KaPow.defaultLevel);
alert("Player 1: " + KaPow.players[0].name + " " + KaPow.players[0].surname);
alert("Player 2: " + KaPow.players[1].name + " " + KaPow.players[1].surname);
alert("Score: " + KaPow.STATS.LIVESLOST);

您创建了一个名为 MyStuff 的对象（您也将其分配给 KaPow）。
它有一堆属性（STATS、difficultyLevel、Players）和一个函数（startGame）。其中一些属性本身就是对象（如统计数据和玩家）等等。例如，STATS 有自己的属性（SHOTS、SCORE、TRIES、LIVESLOST）
函数 startgame 可以对对象的属性进行操作，因为它在对象的范围内（即 this.players[0]）。
You've made an object called MyStuff (which you've also assigned to KaPow).
It's got a bunch of properties (STATS, dificultyLevel, Players), and a function (startGame). Some of those properties are themselves objects (like STATS and Players) and so on and so forth. STATS, for example, has its own properties (SHOTS, SCORE, TRIES, LIVESLOST)
The function, startgame, can operate on the object's properties since it is within the scope of the object (i.e. this.players[0]).
