jinlong / globalVal

Created April 28, 2013 09:07

用 this 定义的方法可以访问局部变量 a，在 prototype 里定义的方法不能访问局部变量 a; 用 this 定义的方法，在 prototype 上定义的方法均可以访问全局变量 b;

	var ClassA = function(){
	var a = 111;
	this.b = 222;
	this.show = function(){
	alert(this.b)
	}
	};
	ClassA.prototype.constructor = ClassA;
	ClassA.prototype.showme = function(){
	alert(this.b)

javascript Math.random() 写了个概率函数（项目中要用，记录一下）

	//probability : 0.6(60%)
	var getRandom = function(probability){
	var probability = probability*10 \|\| 1;
	var odds = Math.floor(Math.random()*10);

	if(probability === 1){return 1};
	if(odds < probability){
	return 1;
	}else{
	return 0;

变量，函数提升

	//变量提升
	var name = "Baggins";

	(function () {
	// Outputs: "Original name was undefined"
