关于导航栏更新修改的请教_html/css_WEB-ITnose
请教一下各位大神，假设一个网站有20个页面，每个页面的顶部导航栏的代码都一样。
导航栏有首页，产品，服务，资讯，四个超链接。
现在客户要求在导航栏添加一个“联系我们”，请问有什么方法可以比较便捷的修改？总不会20个页面一个一个修改吧？
回复讨论(解决方案)
如果导航栏不是共用的只能一个个改
请问如何操作可以共用导航栏？
把这些网页做成动态网页时，它们是共用一个头部的，改一个地方就行了，不然会累死。
当然不会- -你要看他们是否用了cms或者
请问如何操作可以共用导航栏？
这要看具体你的网站了 不同的cms和不同的代码 有不同的修改的方法
把公共代码提取出来，用到的时候再include,这样只修改一个就好了
就算20个网页一起改 就多一个li标签而已嘛。
如果网页都是单独的，每个网页都有各自的导航栏，就得一个一个来，
不过用一般的编辑器都可以一起改的
后来自己尝试了一下，不知道这算不算是“提取出来”，把需要共用的代码复制出来，每一行加上document.write（）；，存储为js文件。再在每个需要使用此代码的页面上，调用此js文件，即可实现多个网页共用一个导航栏。如下图：
