php中有木有办法可以获取js的值
最近在学习discuz,其中修改代码时想把js的值赋值给discuz的全局变量,有木有大神知道可以怎么做?或者用php的方法来获取js的值也可以
回复讨论(解决方案)
php获取的不是js的值,而是js传递到服务端的值!前端可以通常通过两种方式把数据传递到后端:POST GET
$user = $_POST['user']; //php中获取post值$pass = $_GET['pass']; //php中获取get值
而传值一般通过ajax的方式传递!
所以并不是php获取了js的值,而是js将数据传递到服务端,然后php读取post get等全局数组!

就比如说我在当前页面写了一个JS,然后想在当前页面中得到这个值,该怎么写?
你所说的一般用ajax传递,页面的执行顺序是先等php语言解析完成再开始执行解析后的html代码、

你是把html php 和js都写在一起了? 建议把各个文件分离!

不是我写一起了,是在dz上直接修改,我也没办法啊
先弄清楚,服务端跟客户端的执行顺序
php是属于服务端的语言
而JS是客户端的脚本
都是服务端先执行完才会到客户端的,所以你要让服务端去获取客户端的值,唯一的办法,就是让客户端发送请求到服务端
比如使用ajax方式请求

在同一个页面里面也可以这么做吗?
应该是用ajax请求的方式传递到php里面处理吧

问题是是在discuz里面进行的,普通的php,用ajax就可以了
discuz 不是提供有 ajax.get 方法吗?

刚学discuz,不是很熟悉,能简单举个例子吗?就比如说我要做一个下拉框,然后想把下拉框的value赋值给$_G['fid']
其实我没有过 discuz,你看看这个 http://www.baidu.com/s?ie=UTF-8&wd=discuz+ajax%E4%BD%BF%E7%94%A8

好的,我去看看,谢谢
用ajax来传递到php
用ajax来传递到php
小白,能给个实例吗?
<?php $num = "<script> var num = 123;document.write(num);</script>";echo $num;?>
php这样就可以使用js的变量值
<?php $num = "<script> var num = 123;document.write(num);</script>";echo $num;?>
php这样就可以使用js的变量值
好的,谢谢
