Javascript/JSP:如何将一页上的JSP变量值传递给下一页上的javascript变量? [英] Javascript/JSP: How to pass JSP variables value on one page to javascript variables on next page?

问题描述

当前，我正在尝试将JSP值发送给javascript.是否有可能?我的情况如下:

Currently I am trying to send JSP value to javascript. Is it possible? My cases is as follows:

在abc.jsp页上，用户以表格形式输入数据.该信息将在下一页xyz.jsp中发送.我想在xyz.jsp页面javascript中使用此数据.是否有可能?是的，这是怎么做的?

On Page abc.jsp, user enters data in form. Which is send on the next page xyz.jsp. I want to use this data in xyz.jsp pages javascript. Is it possible? Is yes how to do this?

还想知道，如果我自动刷新此页面(或页面的一部分)，即xyz.jsp，那么有可能在没有JavaScript失败或崩溃的情况下发生吗?

also would like to know, if I auto refresh this page(or part of page) ie xyz.jsp then is it possible without javascript failing or crashing?

谢谢.

推荐答案

只需让JSP将其打印为好像是JS变量.假设您在JSP中具有变量${foo}:

Just let JSP print it as if it is a JS variable. Assuming that you've variable ${foo} in JSP:

<script>var foo = '${foo}';</script>

这将在Web浏览器中以

This will end up in webbrowser as

<script>var foo = 'somevalue';</script>

请紧记:JSP在Web服务器上运行并生成HTML. JS是HTML的一部分，可在webbrowser中运行.

Keep in mind: JSP runs at webserver and produces HTML. JS is part of HTML and runs at webbrowser.
