HTML不支持在HTML页面中嵌入HTML页面。要实现此功能，我们可以使用以下选项之一 -

Using Ajax - 进行服务器调用以获取相应的HTML页面并将其设置在HTML控件的innerHTML中。
Using Server Side Includes - JSP，PHP和其他Web端服务器技术可以在动态页面中包含HTML页面。

使用AngularJS，我们可以使用ng-include指令在HTML页面中嵌入HTML页面。

<div ng-app = "" ng-controller = "studentController">
   <div ng-include = "'main.htm'"></div>
   <div ng-include = "'subjects.htm'"></div>
</div>

例子 (Example)

tryAngularJS.htm

<html>
   <head>
      <title>Angular JS Includes</title>
      <script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js">
      </script>
      <style>
         table, th , td {
            border: 1px solid grey;
            border-collapse: collapse;
            padding: 5px;
         }
         table tr:nth-child(odd) {
            background-color: #f2f2f2;
         }
         table tr:nth-child(even) {
            background-color: #ffffff;
         }
      </style>
   </head>
   <body>
