javascript 判断是否大于当前日期

function compareDate(DateOne)
   {
    var OneMonth = DateOne.substring(5,DateOne.lastIndexOf ("-"));
    var OneDay = DateOne.substring(DateOne.length,DateOne.lastIndexOf ("-")+1);
    var OneYear = DateOne.substring(0,DateOne.indexOf ("-"));
  
    if (Date.parse(OneMonth+"/"+OneDay+"/"+OneYear) >
     new Date().getTime())
    {
     return true;
    }
    else
    {
     return false;
    }
  
   }
