How to realize automatic jump in HTML page after 3 seconds

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.

Method 1:

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）

Method 2:

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

Method 3:

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=&#39;res.html&#39;;
			}
		}
	</script>
