js判断60秒以及倒计时示例代码

     if(nowMinitePoint-Biz.AccountCenter.CellPhoneValidation.refreshTime<timeLimit )
     {
         return false;
     }
         return true;
    },

    resetRefreshGet:function() //请求成功之后，调用的方法，把定义的变量重置为当前时间
    {
       var nowTime = new Date();
       var nowMinitePoint=nowTime.getHours()*3600+nowTime.getMinutes()*60+nowTime.getSeconds();
       Biz.AccountCenter.CellPhoneValidation.refreshTime=nowMinitePoint;
    },

 dynamicMessage:function(timeSecond) //倒计时方法 timeSecond为从多少秒开始，比如：60
    {
       var showTimmer;
       if (showTimmer) {
           clearTimeout(showTimmer);
       }

       if(timeSecond==dynamicValidate.refreshTimeLimit)
       {
            var messageRefresh =$.newegg.format(dynamicValidate.refreshSpanMessage,timeSecond);
           $("#spanRefresh").html("<span>"+messageRefresh+"</span>");
            $("#spanRefresh").attr("class","button btn_yanz_disable");
           timeSecond--;
       }

       showTimmer = setTimeout(function () {
           var messageRefresh =$.newegg.format(dynamicValidate.refreshSpanMessage,timeSecond);
           $("#spanRefresh").html("<span>"+messageRefresh+"</span>");
           timeSecond--;
           if (timeSecond < 0) {
               clearTimeout(showTimmer);
               $("#spanRefresh").attr("class","button btn_yanz");
               $("#spanRefresh").html("<span>"+dynamicValidate.refreshMessage+"</span>");

           }
       }, 1000);
    },

    create: function(obj,page,isCancelPhone) //每次请求调用的方法
    {    
        if(!Biz.AccountCenter.CellPhoneValidation.checkRefreshGet(dynamicValidate.refreshTimeLimit)) //每次请求的时候，js检查60s时间间隔
        {

             Biz.AccountCenter.CellPhoneValidation.dynamicMessage(dynamicValidate.refreshTimeLimit);//倒计时
             Biz.AccountCenter.CellPhoneValidation.resetRefreshGet();//重置时间
       });
