I have a requirement to access apache environment variable from js file. I am not sure this is possible or not. 

I used to set Apache variables and access it in php using the following way

Set ENV varialbe 

```
SetEnv PAYPAL_MODE live

```

From php 

```
echo $_SERVER["PAYPAL_MODE"]; 

```

My question is can i access "PAYPAL\_MODE" in my js file 

```
<html>
  <head>
    alert(PAYPAL_MODE);
  </head>
  <body>

  </body>
</html>

```
