This article will introduce to you how to automatically jump to HTML pages after 3 seconds. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.
The simplest one: add code directly in the front
:<meta http-equiv="refresh" content="3;URL=res.html"> //3秒之后自动跳转到res.html,两个属于同一文件下面,要是需要跳转到jsp页面,就需要在url里面填写url地址————(浏览器的地址栏里面写入的数据,如:http://localhost:8080/TestDemo/1.jsp)
Need to use the method in window:
setTimeout | pass Evaluates an expression after specifying a value in milliseconds. |
Example:
window.setTimeout("alert('Hello, world')", 1000);
This is written in js code;
The specific implementation is as follows:
<script type="text/javascript"> onload=function(){ <span style="white-space:pre"> </span>//在进入网页的时候加载该方法 setTimeout(go, 3000); <span style="white-space:pre"> </span> /*在js中是ms的单位*/ }; function go(){ location.href="http://localhost:8080/TestDemo/index.jsp"; } </script>
Automatically execute the go method after 3 seconds and jump directly to the index.jsp page
The flaw of the above two examples is that the jump can be achieved, but I don’t know when to jump. Implement the countdown 3-2-1;
settimeout method can no longer be done;
setInterval | Evaluate an expression after every specified millisecond value. |
Before the same time passes, the corresponding function will be executed. Specific implementation method:
<script type="text/javascript"> onload=function(){ setInterval(go, 1000); }; var x=3; //利用了全局变量来执行 function go(){ x--; if(x>0){ document.getElementById("sp").innerHTML=x; //每次设置的x的值都不一样了。 }else{ location.href='res.html'; } } </script>
