頁面跳轉時參數攜帶與參數接收的幾種方式

1.js中頁面跳轉

 

location.href = path + "/weixin/jsp/submitNewSuccess.jsp?package_number="+package_number

參數接收方式：

 

 

<script type="text/javascript">
    var package_number = "<%=request.getParameter("package_number")%>";
</script>

 

 

2.java代碼中頁面重定向

 

request.setAttribute("openid", openid);

request.getRequestDispatcher("/weixin/jsp/weixinLogin.jsp").forward(request, response);

頁面中參數接收方式：

 

 

var openid =  "<%=request.getAttribute("openid")%>";

把參數在java代碼里面放到session里面：

 

 

request.getSession().setAttribute("openid", openId());

頁面中接收參數的方式：

 

 

<script type="text/javascript">
    var openid =  "<%=request.getSession().getAttribute("openid")%>";
</script>
