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
- 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>夜晚模式</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 = "yellow" } else { oOnoff.src = "http://www.runoob.com/images/pic_bulbon.gif"; oBody.style.background = "white"; oBody.style.color = "black" } } </script> </head> <body id="mybody"> <img id="myonoff" onclick="mySwitch()" src="http://www.runoob.com/images/pic_bulbon.gif" width="40px"> <script> document.write(Date()) </script> </body> </html>
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
css文件:
img { width: 400px; /*设置图片的大小*/ } div.sa { border-style: solid; /*设置边距线条格式*/ border-width: 5px; /*设置边距线条大小*/ border-color: gold; /*设置边距线条颜色*/ width: 400px; /*盒子大小*/ float: left; /*向左浮动*/ margin: 5px; /*设置外边距*/ } div.sa img { width: 100%; /*设置盒子内容的缩放*/ heigh: aute; /*aute是自动对齐格式*/ } div.st { text-align: center; padding: 2px; /*设置内边距*/ } div.sa:hover { border-style: solid; border-width: 5px; border-color: green; } /*设置鼠标经过时产生的变化*/
js文件:
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 = "yellow" } else { oOnoff.src = "http://www.runoob.com/images/pic_bulbon.gif"; oBody.style.background = "white"; oBody.style.color = "black" } }
// match()如果检验到括号里的内容就做以下变动
