属性与方法,都通过自变量定义给对象,然后通过init()方法整体驱动,但是不方便继承,与赋值更改属性(由于属性值没有预留参数,所以,只能单个更改)。下面的方法可以很方便继承和赋予参数
1 function BgAuido(opt){ 2 opt=opt || {}; 3 this.audio = pingfan.$$(‘audio‘), 4 this.audioBtn = pingfan.$$(‘audioBtn‘), 5 this.width=opt.width || 400; 6 } 7 BgAuido.prototype={ 8 say:function(){ 9 alert(this.width); 10 }, 11 init : function(){ 12 var _this=this; 13 window.addEventListener(touchStart,function(){ 14 _this.audio.play(); 15 window.removeEventListener(touchStart,arguments.callee) 16 },false); 17 this.audioBtn.addEventListener(touchStart,function(){ 18 if(_this.audioBtn.className.replace(/(^\s+)|(\s+$)/g,‘‘)==‘off‘){ 19 _this.audio.play(); 20 _this.audioBtn.className=‘‘; 21 }else if(_this.audioBtn.className==‘‘){ 22 _this.audio.pause(); 23 _this.audioBtn.className=‘off‘; 24 } 25 },false) 26 27 } 28 }
