  //将xxxx-xx-xx的时间格式，转换为 xxxx/xx/xx的格式 
  startTime = startTime.replace(/\-/g, "/");
  endTime = endTime.replace(/\-/g, "/");
  //将计算间隔类性字符转换为小写
  diffType = diffType.toLowerCase();
  var sTime =new Date(startTime); //开始时间
  var eTime =new Date(endTime); //结束时间
  //作为除数的数字
  var timeType =1;

    case"second":

PS: Let’s look at js to find the time difference

var date1=new Date(); //开始时间
alert("aa");
var date2=new Date();  //结束时间
var date3=date2.getTime()-date1.getTime() //时间差的毫秒数
//计算出相差天数
var days=Math.floor(date3/(24*3600*1000))
//计算出小时数
var leave1=date3%(24*3600*1000)  //计算天数后剩余的毫秒数
var hours=Math.floor(leave1/(3600*1000))
//计算相差分钟数
var leave2=leave1%(3600*1000)    //计算小时数后剩余的毫秒数
var minutes=Math.floor(leave2/(60*1000))
//计算相差秒数
var leave3=leave2%(60*1000)   //计算分钟数后剩余的毫秒数
var seconds=Math.round(leave3/1000)
alert(" 相差 "+days+"天 "+hours+"小时 "+minutes+" 分钟"+seconds+" 秒")
