最近做重构,有一个功能是,鼠标点击链接后显示不同样式:
代码如下,样式布局我修改后如下,使用bootstrap框架来做。

现在重点说一下:功能实现。
原来代码是这样实现链接点击样式的,给每个链接不同的class,
<span style="color: #0000ff;"><span style="color: #800000;">li </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="menu01"</span><span style="color: #0000ff;">><span style="color: #800000;">a </span><span style="color: #ff0000;">href</span><span style="color: #0000ff;">="page1.html"</span><span style="color: #0000ff;">></span>page1<span style="color: #0000ff;"></span><span style="color: #800000;">a</span><span style="color: #0000ff;">></span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><span style="color: #800000;">li </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="menu02"</span><span style="color: #0000ff;">><span style="color: #800000;">a </span><span style="color: #ff0000;">href</span><span style="color: #0000ff;">="page2.html"</span><span style="color: #0000ff;">></span>page2<span style="color: #0000ff;"></span><span style="color: #800000;">a</span><span style="color: #0000ff;">></span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><span style="color: #800000;">li </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="menu03"</span><span style="color: #0000ff;">><span style="color: #800000;">a </span><span style="color: #ff0000;">href</span><span style="color: #0000ff;">="page3.html"</span><span style="color: #0000ff;">></span>page3<span style="color: #0000ff;"></span><span style="color: #800000;">a</span><span style="color: #0000ff;">></span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span></span></span></span></span></span></span>
然后在page1.html页面定义:
<span style="color: #800000;">.menu01</span>{<span style="color: #ff0000;"> background-color</span>:<span style="color: #0000ff;">#5dc1d1</span>;<span style="color: #ff0000;"> border-radius</span>:<span style="color: #0000ff;">4px</span>; }
同理在page2.html页面定义:
<span style="color: #800000;">.menu02</span>{<span style="color: #ff0000;"> background-color</span>:<span style="color: #0000ff;">#5dc1d1</span>;<span style="color: #ff0000;"> border-radius</span>:<span style="color: #0000ff;">4px</span>; }
在page3.html页面定义:
<span style="color: #800000;">.menu03</span>{<span style="color: #ff0000;"> background-color</span>:<span style="color: #0000ff;">#5dc1d1</span>;<span style="color: #ff0000;"> border-radius</span>:<span style="color: #0000ff;">4px</span>; }
menu菜单这个模块是page1.html,page2.html,page3.html三个页面公共模块,通过include来共享。这样在调用不同页面时,其他链接的样式不生效。所以可以实现被点击的链接显示不同样式的效果。
但是这样的做法是非常糟糕的。同一个样式有多少个页面就重写多少次,不同class名称对应的却是同样的样式。
这样的代码我是无法忍受的。下面用一小段js来实现同样功能。
代码如下:
<span style="color: #0000ff;"><span style="color: #ff00ff;">DOCTYPE html</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><span style="color: #800000;">html </span><span style="color: #ff0000;">lang</span><span style="color: #0000ff;">="zh-CN"</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><span style="color: #800000;">head</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><span style="color: #800000;">meta </span><span style="color: #ff0000;">charset</span><span style="color: #0000ff;">="utf-8"</span> <span style="color: #0000ff;">/></span> <span style="color: #0000ff;"><span style="color: #800000;">link </span><span style="color: #ff0000;">href</span><span style="color: #0000ff;">="css/bootstrap.min.css"</span><span style="color: #ff0000;"> rel</span><span style="color: #0000ff;">="stylesheet"</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><span style="color: #800000;">title</span><span style="color: #0000ff;">></span>starof test<span style="color: #0000ff;"></span><span style="color: #800000;">title</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><span style="color: #800000;">style </span><span style="color: #ff0000;">type</span><span style="color: #0000ff;">="text/css"</span><span style="color: #0000ff;">></span><span style="background-color: #f5f5f5;
