html 如何在里面加一个计时器啊 能够实现数字从1-200 循环跳动 且指针也跟随变化

html 如何在里面加一个计时器啊 能够实现数字从1-200 循环跳动 且指针也跟随变化,第1张

写了一个简单地定时器使数字循环跳动的,每秒加一。希望能帮到你

<script>

window.onload=function ()

{

var oDiv=document.getElementById('div1')

var value=1

setInterval(function(){

oDiv.innerHTML=value

value++

if(value>200){

value=1

}

},1000)

}

</script>

</head>

<body>

<div id="div1" ></div>

</body>

</html>

添加计时器的方法如下:

1、首先新建一个html页面,并设置一个按钮;

2、然后给这个按钮绑定一个函数;

3、接着设置一个变量用来保存定时器;

4、最后在Function里面写实现代码即可。
