jsp中的cookie用法小实例
这个小实例有三个页面
index.jsp页面内容如下:
You can choose the list you want to operate:
<br>
<a href="setCookie.jsp">Write Cookie</a>
<br>
<a href="getCookie.jsp">Read Cookie</a>
setCookie.jsp页面内容如下:
<%
Cookie cookie = new Cookie("password","anony");
cookie.setMaxAge(60);
response.addCookie(cookie);
cookie = new Cookie("userName","liming");
response.addCookie(cookie);
%>
getCookie.jsp页面内容如下:
<%
Cookie cook[] = request.getCookies();
for(int i = 0;i < cook.length;i++){
if(cook[i].getName().equals("userName")){
request.setAttribute("userName",cook[i].getValue());
}
if(cook[i].getName().equals("password")){
request.setAttribute("password",cook[i].getValue());
}
}
%>
<input type="text" name="userName" value="${userName }"><br>
<input type="text" name="password" value="${password }">
说明:在进入index.jsp页面的时候先点击Read Cookie,看到的输入框中什么也没有,
返回,先点击Write Cookie,然后点击Read Cookie 你会看到输入框中就有值
了,这就是Cookie的自动填充功能。
