js鼠标悬停显示文字实例,第1张

一、首先需要div布局:

<!DOCTYPE html>

<html lang="en">

<head>

<meta charset="UTF-8">

<title>js悬停</title>

<style type="text/css">

p {

width: 200px

height: 200px

background-color: skyblue

text-align: center

line-height: 200px

}

</style>

</head>

<body>

<p id="txt">我是一个DIV</p>

<script type="text/javascript">

var txt = document.getElementById('txt')

txt.setAttribute("title","鼠标悬停了")

</script>

</body>

</html>

二、div实在的在开发工具里面的代码效果如下截图:

三、这段代码最主要的重点是如下:

<script type="text/javascript">

var txt = document.getElementById('txt')

txt.setAttribute("title","鼠标悬停了")

</script>

四、实际代码在浏览器的渲染如下:

如<meta http-equiv="Content-Type" content="text/htmlcharset=gb2312" />
