JS模拟栈（面向对象）

var Stack = function(MAXSIZE) {
		this.MAXSIZE = MAXSIZE;
		this.InitStack();
	};
Stack.prototype = {
	Stack: function() {
		this.data = new Array(this.MAXSIZE);
		this.top = 0;
	},
	InitStack: function() {
		this.S = new this.Stack();
	},
	ClearStack: function() {
		this.S = new Array(this.MAXSIZE);
	},
	StackEmpty: function() {
		return this.S.top == -1 ? true : false;
	},
	GetTop: function() {
		if (this.S.top == -1) return false;
		return this.S.data[this.S.top];
	},
	Push: function(e) {
		if (this.S.top == this.MAXSIZE - 1) return false;
		this.S.top++;
		this.S.data[this.S.top] = e;
		return true;
	},
	Pop: function() {
		if (this.S.top == -1) return false;
		this.S.top--;
	},
	StackLength: function() {

	}
};
window.onload = function() {
	var S = new Stack(10);
	S.Push(1);
	S.Push(2);
	S.Pop();
	S.Push(3);
	S.Pop();
	var t = S.GetTop();
