夜间模式的开启与关闭，父模板的制作

夜间模式的开启与关闭
1. 放置点击的按钮或图片。
2. 定义开关切换函数。
3. onclick函数调用。
父模板的制作
1. 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。
2. 汇总相关的样式形成独立的css文件。
3. 汇总相关的js代码形成独立的js文件。
4. 形成完整的base.html+css+js

1.代码如下：

light1.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
 <script language="javascript" type="text/javascript" src="../static/js/light1.js"></script>
</head>
<body id="myBody">
<img id="myOnOff" onclick="mySwitch()" src="http://www.runoob.com/images/pic_bulbon.gif" width="40px">
<script>

    document.write("点击有惊喜!&nbsp Now is&nbsp")
     document.write(Date())
</script>
<img id="gui" onclick="mySwitch()" src="" width="1400px">




</body>
</html>

light1.js

function mySwitch() {
    var oBody = document.getElementById("myBody");
    var oOnOff = document.getElementById("myOnOff");
    var ogui = document.getElementById("gui");
    if (oOnOff.src.match('bulbon')) {

        oOnOff.src = "http://www.runoob.com/images/pic_bulboff.gif";
        oBody.style.backgroundColor = "black";
        oBody.style.color = "white";
        ogui.src = "https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1509563443074&di=b1bbb3f5714a580e2211e281124636c2&imgtype=0&src=http%3A%2F%2Fpic15.nipic.com%2F20110709%2F7854247_221301558161_2.jpg";
    } else {
        oOnOff.src = "http://www.runoob.com/images/pic_bulbon.gif";
        oBody.style.backgroundColor = "white";
        oBody.style.color = "black";
        ogui.src = "";

    }
}

运行结果：

2.a
