UC知道JSP中一个值传递的问题
来源：百度知道 编辑：UC知道 时间：2024/05/13 03:21:06
大家帮忙看看我的代码 哪里错了啊 ？
<html>
<body>
<%@ page language="java" %>
<jsp:include page="test6-5.jsp" >
request.setAttribute(name="one" value=100);
request.setAttribute(name="two" value=200);
</jsp:include>
</body>
</html>
test6-5.jsp：
<htmL>
<body>
<pre>
<%@ page language="java" %>
<% Integer one1=(Integer)request.getAttribute("one");%>
<% Integer two1=(Integer)request.getAttribute("two");%>
<%=one1 %>
<%=two1 %>
</pre>
</body>
</html>
<html>
<body>
<%@ page language="java" %>
<jsp:include page="test6-5.jsp" >
request.setAttribute(name="one" value=100);
request.setAttribute(name="two" value=200);
</jsp:include>
</body>
</html>
test6-5.jsp：
<htmL>
<body>
<pre>
<%@ page language="java" %>
<% Integer one1=(Integer)request.getAttribute("one");%>
<% Integer two1=(Integer)request.getAttribute("two");%>
<%=one1 %>
<%=two1 %>
</pre>
</body>
</html>
request.setAttribute("one",Integer.parseInt(100));
request.setAttribute("two", Integer.parseInt(200));
不能放基本数据类型
request.setAttribute("one", "100");
request.setAttribute("two", "200");
呵呵，楼上的少了个分号哦
request.setAttribute(name="one" value=100);
request.setAttribute(name="two" value=200);
我没有见过这种写法，正常情况下应该是:
request.setAttribute("one", "100");
request.setAttribute("two", "200");
