在写纯Html网站的时候，每个页面的头部菜单、js、css和底部说明都是同样的，有的时候你要改，就要一个一个的去改，通过下面方法将这些相同的抽取出来，方便后期维护！
希望能帮到你～！
在applyBusiness.html页面引入公共页头header.html。
1、applyBusiness.html：
<!DOCTYPE html>
<html>
<head>
<title>我的申请任务</title>
<script type="text/javascript" charset="utf-8" src="../../../js/platform/system/header.js"></script>
</head>
<body>
<div class="container">
<div class="mainBody mt-20 applyBusiness">
<form class="form-inline mt-30" id="searchFormId">
<div class="clearfix">
<div class="form-group col-sm-4 col-md-4 padding-0">
<label class="text-right labelBlock">科信业务事项：</label>
<select id="businessType" name="businessType" class="form-control optionLength">
<option> </option>
<option value="104" servicetype="1">故障申报</option><option value="105" servicetype="2">服务申请</option>
</select>
</div>
<div class="form-group col-sm-4 col-md-4 padding-0">
<label class="text-right labelBlock">状态：</label>
<select id="serviceStatus" name="serviceStatus" class="form-control optionLength">
<option value="all">全部</option>
<option value="pending">待提交</option>
<option value="handling">办理中</option>
<option value="completed">已办结</option>
</select>
</div>
<div class="form-group col-sm-4 col-md-4 padding-0">
<label class="text-right labelBlock">业务来源：</label>
<select id="serviceSource" name="serviceSource" class="form-control optionLength">
</select>
</div>
</div>
<div class="clearfix mt-20">
<div class="col-sm-5 col-md-5 halfWidth">
<div class="form-group" id="applyTime1">
<label class="text-right" for="startApplyDate">申请时间：</label>
<input type="text" readonly="readonly" size="16" value="" id="startApplyDate" name="startApplyDate" class="form-control form_date" data-date-format="yyyy-mm-dd">
</div>
<div class="form-group" id="applyTime2">
<label for="endApplyDate">-</label>
<input type="text" readonly="readonly" size="16" value="" id="endApplyDate" name="endApplyDate" class="form-control form_date" data-date-format="yyyy-mm-dd">
</div>
</div>
<div class="col-sm-2 col-md-2 margin-top-20">
<button id="search-btn" type="button" class="btn btn-primary btn-warning marginLeft">搜索</button>
<button type="button" id="resetId" class="btn btn-primary btnIp">重置</button>
</div>
</div>
</form>
<table style="margin-top:30px" id="table"></table>
</div>
</div>
</body>
</html>
2、header.js:
/**
* 引用JS和CSS头文件
*/
var rootPath = getRootPath(); //项目路径
/**
* 动态加载CSS和JS文件
*/
var dynamicLoading = {
meta : function(){
document.write('<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">');
},
css: function(path){
if(!path || path.length === 0){
throw new Error('argument "path" is required!');
}
document.write('<link rel="stylesheet" type="text/css" href="' + path + '">');
},
js: function(path, charset){
if(!path || path.length === 0){
throw new Error('argument "path" is required!');
}
document.write('<script charset="' + (charset ? charset : "utf-8") + '" src="' + path + '"></script>');
}
};
/**
* 取得项目路径
* @author wul
*/
function getRootPath() {
//取得当前URL
var path = window.document.location.href;
//取得主机地址后的目录
var pathName = window.document.location.pathname;
var post = path.indexOf(pathName);
//取得主机地址
var hostPath = path.substring(0, post);
//取得项目名
var name = pathName.substring(0, pathName.substr(1).indexOf("/") + 1);
return hostPath + name + "/";
}
//动态生成meta
dynamicLoading.meta();
//动态加载项目 JS文件
dynamicLoading.js(rootPath + "/js/common/jquery-1.9.1.min.js", "utf-8");
dynamicLoading.js(rootPath + "/js/common/bootstrap.min.js", "utf-8");
dynamicLoading.js(rootPath + "/js/process/center/common/baseApp.js", "utf-8");
dynamicLoading.js(rootPath + "/js/process/center/common/bootstrap-datetimepicker.min.js", "utf-8");
dynamicLoading.js(rootPath + "/js/process/center/common/bootstrap-datetimepicker.zh-CN.js", "utf-8");
dynamicLoading.js(rootPath + "/js/process/center/common/jquery.dataTables.js", "utf-8");
dynamicLoading.js(rootPath + "/js/platform/system/loadHeader.js", "utf-8");
//动态加载项目 CSS文件
dynamicLoading.css(rootPath + "/css/common/bootstrap-3.3.5/css/bootstrap.min.css");
dynamicLoading.css(rootPath + "/css/common/bootstrap-3.3.5/css/bootstrap-responsive.css");
dynamicLoading.css(rootPath + "/css/workflow/css/jquery.dataTables.css");
dynamicLoading.css(rootPath + "/css/workflow/css/newWorkflow.css");
3、loadHeader.js
$(function(){
$(".container").append('<div id="header"></div>');
$("#header").load(getRootPath() + "header.html");
});
4、header.html
<nav class="navbar navbar-default navbar-fixed-top navWhole">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed navToggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#"></a>
<p class="navbar-text navHeader">科信服务门户</p>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav navbar-right navToggle">

</ul>
</li>
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>
