在HTML页面中引入公共的部分的代码
在做前端网页的时候，会涉及到很多界面，有的时候，这些界面都会有重复的代码，比如侧边栏菜单的重复代码，头部导航的 重复代码，底部的重复代码，这个时候，为了使每个页面的代码看起来简洁明了，我们需要把这些重复的代码放到公共的页面里面，在具体页面只需引用即可。
主要代码
<div id="head"></div>
<div id="side"></div>
<script>
$("#head").load("com/head.html");
$("#side").load("com/side.html");
</script>
1：在文件里面新建head.html和side.html
2：打开head.html，side.html类似 将头部重复的代码复制在head.html界面里面
head.html
<div class="header-right">

</div>3：在当前界面（test.html）引入公共代码
test.html
<!DOCTYPE HTML>
<html>
<head>
<title>Home</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link href="css/bootstrap.css" rel="stylesheet" type="text/css" media="all">
<link href="css/style.css" rel="stylesheet" type="text/css" media="all" />
<link href="css/font-awesome.css" rel="stylesheet">
<script src="js/jquery-2.1.1.min.js"></script>
<script src="js/bootstrap.js">
</script>
</head>
<body>
<div class="page-container">
<div class="left-content">
<div class="mother-grid-inner">
<!--头部导航导入-->
<div class="header-main">
<div id="head"></div>
</div>
<div class="inner-block">
<div class="climate" style="height: 2123px;">
内容
</div>
</div>
</div>
</div>
<!--侧边栏导入-->
<div class="sidebar-menu">
<div id="side"></div>
</div>
<div class="clearfix"> </div>
</div>
<script>
$("#head").load("com/head.html");
$("#side").load("com/side.html");
</script>
</body>
</html>4：这个时候，就化繁为简了，页面代码看上去也就清爽多了
