工程目录src下面有test包,包中有类Cons,属性如下
Java code:
package test;
public class Cons {
public static int num = 13;
}
index.jsp文件如下:
HTML code:
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
</head>
<script type="text/javascript">
function ini(){
var addr = <%=test.Cons.num%>;
alert(addr);
<%
out.write("11");
%>
}
</script>
<body onload="ini()">
</body>
</html>
1.如果不可以,那么:这里的 alert(addr)为什么可以正确的打印出13?
2.如果可以,那么:打印语句后面的<% out.write("11");%>为什么没有显示出来?
只有75分全送了,希望高手解答!谢谢!
你用下el表达式，应该可以
是可以的
你的解析后事这样的
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
</head>
<script type="text/javascript">
