         //模拟日历需求：每天打开页面都能定时显示年月日和星期几

         //步骤：创建一个当前日期的日期对象，获取其中的年月日和星期，赋值给div

         //1.创建一个当前日期的日期对象

         var date = new Date();

         //2.获取其中的年月日和星期

         var year = date.getFullYear();

         var month = date.getMonth();

         var day = date.getDate();

         var week = date.getDay();

         // console.log(year+" "+month+" "+day+" "+week);

         //3.赋值给div

         var arr =["星期日","星期一","星期二","星期三","星期四","星期五","星期六"];

         var div = document.getElementsByTagName("div")[0];

         div.innerText = "今天是："+year+"年"+(month+1)+"月"+day+"日"+arr[week];
