使用javascript变量设置PHP变量 [英] Using a javascript variable to set PHP variable

问题描述

可能重复：

从PHP变为JavaScript的变量

从PHP访问JavaScript变量

我目前有这条线代码：

displaystatus('CALLER IS: '+inCallingNum);

用于在页面上显示消息（例如）CALLER IS：01234 567890。

which is being used to display a message on the page saying (e.g.) CALLER IS: 01234 567890.

我现在需要做的是在PHP变量$ user_number中设置inCallingNum变量的值。这可能吗？

What I need to do now is set the value of the inCallingNum variable in a PHP variable $user_number. Is this possible?

我试过这样的事情，但没有任何运气：

I tried something like this, but didnt have any luck with it:

<?php $user_number ?> = inCallingNum;

感谢您的帮助

编辑：

这是设置inCallingNum的地方：

This is where inCallingNum is set:

inCallingNum = inCallingNum.slice(inCallingNum.lastIndexOf(",")+1, inCallingNum.length);

编辑2：

我会试着解释一下我想要做的更清楚。我目前所拥有的是2页，显示所有信息的主页和查询数据库的第2页，并提取用户的个人资料。当jall变量inCallingNum发生变化时，我需要将其发送到user_data.php页面并更新信息以显示新人的个人资料。

I'll try to explain what I'm trying to do more clearly. What I have at the moment is 2 pages, the main page which displays all of the information and a 2nd page which queries the database and pulls out the user's profile. When the javascript variable inCallingNum changes, I need to send this to the user_data.php page and update the information to show the new person's profile.

推荐答案

Php是服务器端代码，javascript是客户端代码。无法按照您的要求进行操作，您必须通过调用服务器来设置 $ user_number 。

Php is server-side code, javascript is client-side code. It is not possibile to do what you're asking, you have to set $user_number with a call to the server.

当您使用javascript时，您已经收到了服务器的响应，因此您正在处理服务器端操作的结果，您无法从结果中更改源。

When you are working with javascript you have already had the response from the server, so you are working with the result of the server-side actions, you cannot change the source from the result.
