添加暂停和恢复到我的代码

Question

如何在移动浏览器处于后台时自动暂停计时器，并在我们将其用于我的代码时恢复计时器。我没有任何想法，我尝试使用phonegap事件功能，但我不能让它工作。关于如何编码的任何想法......

<script type="text/javascript">

var zxcMatch={

 Reset:function(id){
  var o=this[id],z0=0;
  if (o){
   clearTimeout(o.to);
   o.time[1]=null;
   for (;z0<o.imgs.length;z0++){
    o.imgs[z0].style.visibility='visible';
   }
   o.cnt=z0/2;
   o.lst=null;
  }
 },

 init:function(o){
  var id=o.ParentID,imgs=document.getElementById(id).getElementsByTagName('IMG'),z0=0;
  o.imgs=imgs;
  for (;z0<imgs.length;z0++){
   this.addevt(imgs[z0],'mouseup','match',o,imgs[z0]);
  }
  o.time=[typeof(o.Timer)=='function'?o.Timer:null];
  o.cnt=z0/2;

   o.time[1]=new Date();
   o.to=setInterval(function(){ o.time[0](o,Math.floor((new Date()-o.time[1])/1000)); },1000);
  }
  if (!o.lst){
   o.lst=img;
  }
  else {
   if (o.lst.className==img.className&&o.lst!=img){
    img.style.visibility=o.lst.style.visibility='hidden';

  o.addEventListener?o.addEventListener(t,function(e){ return oop[f](p,p1);},false):o.attachEvent?o.attachEvent('on'+t,function(e){ return oop[f](p,p1); }):null;
