通过servlet更新当前的jsp页面? [英] Update current jsp page through servlet?

问题描述

作为大学网络项目的一部分，我将编写一个网络商店代码.

As a part of a web project in college, I'm going to code a webshop.

我有一个Java Servlet，在其中将项目添加到购物篮中.可以从列出了项目的其他JSP站点调用此servlet.我无法弄清楚的是如何刷新页面.

I have a Java servlet where I add items to a basket. This servlet can be called from different JSP sites where i have items listed. What i cant figure out is how to refresh the page.

我一直在搜寻，发现了两个建议；

I have been googling around, and found 2 proposals;

response.setHeader("Refresh", "1");

或

response.sendRedirect("/demo.jsp")

我不能真正使用解决方案2，因为我不知道必须重定向到哪个项目，就像它从多个JSP站点调用的那样，我只想停留在同一页面上.

I can't really use solution 2, because I dont know what item I have to redirect to, as it called from several JSP sites, and I just want to stay on the same page.

根据我对解决方案1的了解，这不仅是一次刷新，而是一个脚本，该脚本以一秒钟的间隔不断更新网站.

And from what I understand from solution 1, that isn't just a 1 time refresh, but a script that keep updating the site with one-second intervals.

那么任何人都可以帮助我:将商品添加到购物篮后，如何仅刷新一次网站?

So can anyone help me: How can I refresh the site just once, when an item is added to my basket?

推荐答案

如果您只想刷新页面，则可以调用reload函数

If you just want to refresh the page you can call reload function

示例

<input type="button" value="Reload Page" onClick="document.location.reload(true)">
