本文实例讲述了JS模式之单例模式基本用法。分享给大家供大家参考。具体如下：
rush:js;">
//singleton
var SingletonTester = (function(){
function Singleton(options){
options = options || {};
this.name = "SingletonTester";
this.pointX = options.pointX || 6;
this.pointY = options.pointY || 10;
};
var instance;
var _static = {
name : "SingletonTester",getInstance : function(options){
if(instance === undefined){
instance = new Singleton(options)
};
return instance;
}
};
return _static;
})();
希望本文所述对大家的javascript程序设计有所帮助。
