将javascript变量传递给php代码

问题描述

即时通讯将JavaScript中的一个变量传递给一行PHP包含代码以创建一个更动态的脚本。但到目前为止，我还没有设法实现这一目标。

逻辑如下：

下面的代码 - 我想用javascript变量替换'textfile.txt'。

  descrip2.innerHTML =< ？php include（'textfile.txt'）;？>; 
  

显示：

  var thisfile = [userinput]; 
 descrip2.innerHTML =<？php include（thisfile）;？>; 
  

有关如何实现此目的的任何想法？我知道，即时通讯尝试加入客户端脚本与服务器端，但这不能以我尝试的方式完成吗？也许有一些调整？
我不想为一些应该如此直观和简单的东西写出一百个PHP脚本...... :(不是如果我可以避免它... ...

解决方案

如果我理解你的问题，你不能这样做。

你可以使用ajax请求。使用jQuery你可以这样做：

  var thisfile = [userinput]; 
 $（descrip2）.load（这个文件）; 
  

或者自己做ajax请求。

im trying to pass a variable from javascript into a line of PHP include code to create a more dynamic script. But so far I've not managed to achieve this.

The logic is as follows:

Looking at the below code - i want to replace the 'textfile.txt' with a javascript variable.

descrip2.innerHTML = "<?php include('textfile.txt'); ?>";

to show:

var thisfile = [userinput];
descrip2.innerHTML = "<?php include(thisfile); ?>";

Any ideas on how to achieve this? I know that im trying to join client side scripts with server side, but can this not be done the way im trying? Maybe with a few tweaks?I don't want to write a hundred php scripts for something that should be so intuitive and simple... :( not if i can avoid it...

解决方案

If I understood your question you can't do like that.

you can go with ajax request. If you use jquery you can do like this:

var thisfile = [userinput];
$(descrip2).load(thisfile);

or do ajax request by yourself..
