bootstrap 實現導航欄不變 內容變
阿新 • • 發佈：2019-01-29
當我們在建web專案時會建立多個頁面，如果每一個頁面都需要通過同樣的導航欄索引呈現不同的內容，我們可以建一個導航頁，在其他頁面中加入這個導航頁，能最大實現重用率
這裡介紹兩種實現方法
靜態包含
<%@include file="temple.jsp"%>動態包含
<jsp:include page="temple.jsp" flush="true"/>首先建一個導航頁
<html> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <meta name="description" content=""> <meta name="author" content=""> <link rel="icon" href="../../favicon.ico"> <title>Dashboard Template for Bootstrap</title> <link href="css/bootstrap.min.css" rel="stylesheet"> <link href="css/ie10-viewport-bug-workaround.css" rel="stylesheet"> <link href="css/dashboard.css" rel="stylesheet"> <script src="js/ie-emulation-modes-warning.js"></script> </head> <body> <nav class="navbar navbar-inverse navbar-fixed-top"> <div class="container-fluid"> <div class="navbar-header"> <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar"> <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="#">Project name</a> </div> <div id="navbar" class="navbar-collapse collapse"> <ul class="nav navbar-nav navbar-right"> <li> <a href="#">Dashboard</a> </li> <li> <a href="#">Settings</a> </li> <li> <a href="#">Profile</a> </li> <li> <a href="#">Help</a> </li> </ul> <form class="navbar-form navbar-right"> <input type="text" class="form-control" placeholder="Search..."> </form> </div> </div> </nav> <div class="container-fluid"> <div class="row"> <div class="col-sm-3 col-md-2 sidebar"> <ul class="nav nav-sidebar"> <li class="active"> <a href="index.jsp">Overview <span class="sr-only">(current)</span></a> </li> <li> <a href="list.jsp">Reports</a> </li> <li> <a href="login.jsp">Analytics</a> </li> <li> <a href="#">Export</a> </li> </ul> <ul class="nav nav-sidebar"> <li> <a href="">Nav item</a> </li> <li> <a href="">Nav item again</a> </li> <li> <a href="">One more nav</a> </li> <li> <a href="">Another nav item</a> </li> <li> <a href="">More navigation</a> </li> </ul> <ul class="nav nav-sidebar"> <li> <a href="">Nav item again</a> </li> <li> <a href="">One more nav</a> </li> <li> <a href="">Another nav item</a> </li> </ul> </div> <div class="col-sm-9 col-sm-offset-3 col-md-10 col-md-offset-2 main"> </div> </div> </div> </div> <!-- Bootstrap core JavaScript ================================================== --> <!-- Placed at the end of the document so the pages load faster --> <script src="js/jquery.min.js"></script> <script> window.jQuery || document.write('<script src="js/jquery.min.js"><\/script>') </script> <script src="js/bootstrap.min.js"></script> <script src="js/holder.min.js"></script> <script src="js/ie10-viewport-bug-workaround.js"></script> </body> </html>
然後在導航頁上新增連結，在跳轉頁面head中新增如下程式碼，並新增格式
<jsp:include page="index.jsp" flush="true"/> <div class="col-sm-9 col-sm-offset-3 col-md-10 col-md-offset-2 main"></div><html> <head> <base href="<%=basePath%>"> <jsp:include page="index.jsp" flush="true"/> <title>My JSP 'update.jsp' starting page</title> </head> <body> <div class="col-sm-9 col-sm-offset-3 col-md-10 col-md-offset-2 main"> <form action="loginservlet?op=login" method="post"> <table> <tr> <th>姓名:</th> <td><input type="text" name="name"/></td> </tr> <tr> <th>密碼:</th> <td><input type="text" name="password"/></td> </tr> <tr> <td colspan="2" align="center"> <button type="submit">登入</a></td> </tr> </table> </form> </div> </body> </html>
實現效果如圖
