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>
