## 5, SetInterval () # (calculated) to call a function or calculate an expression (in lay terms, set a few milliseconds to run the program)

Format: setInterval ('js code or function', the interval between executing the function or code)

<!--方法1-->
nbsp;HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">


<meta>
<title>window对象setInterval方法</title>
<script>
	setInterval(&#39;test();&#39;,1000);
	function test(){
		alert("hello world")
	}
</script>


	





<!--方法2-->
nbsp;HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">


<meta>
<title>window对象setInterval方法</title>
<script>
	setInterval(&#39;alert("hello world");&#39;,1000);

setInterval can keep looping. If you want to stop, you can use window.clearInterval( );

nbsp;HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">


<meta>
<title>window对象setInterval方法循环取消方法--clearInterval</title>
<script>
	var 控制循环=setInterval(&#39;alert("hello world");&#39;,3000);
</script>


	<input>

setTimeout and setInterval are both timers in JS. You can specify a delay time before executing a certain operation, the difference is that setTimeout stops after performing an operation after the specified time

Code embedded

nbsp;HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">


<meta>
<title>window对象setTimeout方法</title>
<script>
	var 控制循环=setTimeout(&#39;alert("hello world");&#39;,3000);
</script>

Embedded functional

nbsp;HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">


<meta>
<title>window对象setTimeout方法</title>
<script>
	var 控制循环=setTimeout(&#39;test()&#39;,3000);
	function test(){
		alert("hello world");
	}
</script>

Cancel the timeout set by the setTimeout method (stop setTimeout())

nbsp;HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">


<meta>
<title>window对象setTimeout方法取消方法--clearTimeout</title>
<script>
	var 控制循环=setTimeout(&#39;test()&#39;,3000);
