jquery属性选择器的用法
1、选择指定属性值等于给定字符串或者以改字符串为前缀的元素。
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%
pageContext.setAttribute("APP_PATH",request.getContextPath());
%>
<!-- 此时表示根据设备的大小调整页面的显示宽度 -->
<meta name="viewport" content="width=device-width,initial-scale=1">
<script type="text/javascript" src="${APP_PATH}/static/js/jquery-3.2.1.min.js"></script>
<link rel="stylesheet" href="${APP_PATH}/static/bootstrap-3.3.7-dist/css/bootstrap.min.css" />
<script type="text/javascript" src="${APP_PATH}/static/bootstrap-3.3.7-dist/js/bootstrap.min.js"></script>
<script type="text/javascript">
$(function() {
$("[hreflang=en]").css("color","red");
})
</script>
<html>
<body>
<div>
<div>
<div>
<a href="#" hreflang="en">英文</a>
<a href="#" hreflang="zh">中文</a>
</div>

</div>
</body>
</html> <script type="text/javascript" src="${APP_PATH}/static/bootstrap-3.3.7-dist/js/bootstrap.min.js"></script> <script type="text/javascript"> $(function() { $("input[name~='man']").val("猛男"); }) </script> <html> <body> <div class="container"> <div class="row"> <div class="col-md-3"> <input name="man-news" /> </div> <div class="col-md-3"> <input name="milk man" /> </div> <div class="col-md-3"> <input name="letterman2" /> </div> <div class="col-md-3"> <input name="newmilk" /> </div> </div> </div> </body> </html> <script type="text/javascript" src="${APP_PATH}/static/bootstrap-3.3.7-dist/js/bootstrap.min.js"></script> <script type="text/javascript"> $(function() { $("input[id][name$='man']").val("百度"); }) </script> <html> <body> <div class="container"> <div class="row"> <div class="col-md-3"> <input name="man-news" id="man-news"/> </div> <div class="col-md-3"> <input name="milkman" /> </div> <div class="col-md-3"> <input id="letterman" name="letterman" name="new-letterman" /> </div> <div class="col-md-3"> <input name="newmilk" /> </div> </div> </div> </body> </html> 7、运行程序，查看程序的执行结果，只有<input id="letterman" name="letterman" name="new-letterman" />才能设置到值。
