This time I will bring you JS jQuery to display the boot time (accurate to seconds). What are the precautions for JS jQuery to display the boot time. The following is a practical case, let's take a look.

Implementation principle:

Bind the click event to the close button, and trigger the animation effect after clicking. Using jQuery's animate method, first change the height of the box displaying the weather to 0, then change the width of the entire box containing weather and events to 0, and finally set the display attribute value to none to make the close button disappear.

Implementation code:

<!DOCTYPE html>
<html>
<head>
 <title>仿360开机效果</title>
 <meta charset="utf-8">
 <style type="text/css">
  *{
   padding: 0;
   margin: 0;
  }
  .box{
   width: 320px;
   position: fixed;
   bottom: 0;
   right: 0;
   box-shadow: 1px 1px 10px #2d2d2d;
  }
  #close{
   position: absolute;
   top: 0;
   right: 0;
   width: 30px;
   height: 20px;
   cursor: pointer;
   background-color: red;
   color: pink;
   font-weight: bold;
   text-align: center;
  }
  .hd{
   width: 320px;
   height: 300px;
   background-color: #03c03c;
   color: #fff;
   font-size: 70px;
   line-height: 300px;
   text-align: center;
  }
  .bd{
   width: 320px;
   height: 100px;
   background-color: #fffc00;
   font-size: 30px;
   line-height: 100px;
   text-align: center;
  }
 </style>
</head>
<body>
<p class="box">
 <span id="close">X</span>
 <p class="hd" id="t">1分12秒</p>
 <p class="bd" id="b">天气：晴天</p>
</p>
<!-- 引入jQuery -->
<script type="text/javascript" src="./jquery1.0.0.1.js"></script>
<script type="text/javascript">
 window.onload = function(){
  var close = document.getElementById("close");
  var box = close.parentNode;
  var b = document.getElementById("b");
  // 给关闭按钮绑定点击事件
  close.onclick = function(){
   animate(b, {"height":0}, function(){
    animate(box,{"width":0});
   });
   close.style.display = "none";
  }
 }
</script>
</body>
</html>

PS: JS implements time countdown

<script type="text/javascript">
var maxtime = 1350057600 //截止到的日期
var now=parseInt((new Date().getTime())/1000);//获取当前的日期
var cha_time=maxtime-now;//中间所差的时间

The following method combines the difference in time into a countdown string, and then puts it in the corresponding position of the page to achieve real-time refresh

function CountDown(){ 
if(cha_time>=0){
var day = Math.floor(cha_time/3600/24);
var hour= Math.floor((cha_time/3600)%24);
var minutes = Math.floor((cha_time/60)%60); 
var seconds = Math.floor(cha_time%60); 
msg = "离结束还有"+day+"天"+hour+"小时"+minutes+"分"+seconds+"秒"; 
$(".ws_sg_con_big,.ws_sg_con_small").find("dd").html(msg);
--cha_time; 
} 
else{ 
clearInterval(timer); 
alert("时间到，结束!"); 
} 
} 
timer = setInterval("CountDown()",1000); 
</script>
