是否应该在包含在.php文件中的.js文件中看到PHP变量 [英] Is a PHP variable supposed to be seen in a .js file included into a .php file

问题描述

是否应该在包含在.php

文件中的.js文件中看到PHP变量？


我有一个客户端javascript代码存储在.js文件中，包含

到PHP文件中使用

< script src =" filename.js>< / script>


此代码初始化一个Javascript变量

var u =" string";


字符串应该是值$ HTTP_HOST


所以，当初始化这个变量时


var u =<？ echo $ HTTP_HOST;？> ;;


我引用了javascript消息语法错误


我做错了什么，或PHP变量是没有在包含js

文件中看到？

Is a PHP variable supposed to be seen in a .js file included into a .php
file?

I have a client side javascript code stored in a .js file which is included
into a PHP file using
<script src="filename.js></script>

This code initialises a Javascript variable
var u="string";

The string is supposed to be the value of $HTTP_HOST

So, when initialise this variable like

var u=<? echo $HTTP_HOST;?>;

I sterted getting a javascript message Syntax Error

Am I doing something wrong, or PHP variables are not seen in included js
files?

推荐答案

HTTP_HOST


所以，初始化这个变量就像


var u =<？ echo

HTTP_HOST

So, when initialise this variable like

var u=<? echo

HTTP_HOST;？> ;;

HTTP_HOST;?>;

files?
