夜间模式的开启与关闭，父模板的制作

1、夜间模式的开启与关闭

放置点击的按钮或图片。
定义开关切换函数。

onclick函数调用。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>夜间模式</title>
    <script>
        function mySwitch() {
            var oBody = document.getElementById("myBody");
            var oOnOff= document.getElementById("myOnOff");
            if (oOnOff.src.match("bulbon")){
                oOnOff.src="http://www.runoob.com/images/pic_bulboff.gif";
                oBody.style.background="black";
                oBody.style.color="white";
            }else {
                 oOnOff.src="http://www.runoob.com/images/pic_bulbon.gif";
                oBody.style.background="white";
                oBody.style.color="black";
            }
        }
    </script>
</head>
<body id="myBody" style="color: black;background: white;">
<img id="myOnOff" onclick="mySwitch()" src="http://www.runoob.com/images/pic_bulbon.gif" width="60px">
<script>
    document.write(Date())
</script>
</body>
</html>

2、父模板的制作

制作网站网页共有元素的父模板html，包括顶部导航，中间区块划分，底部导航，底部说明等。
汇总相关的样式形成独立的css文件。
汇总相关的js代码形成独立的js文件。
形成完整的base.html+css+js

html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>登陆测试界面</title>
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
    <link href="../static/css/10.31.css" rel="stylesheet" type="text/css" charset="UTF-8">
    <script src="../static/js/js.js"></script>
