I have a simple js file:

```
//base.js

...
var url = '/post/' + id + '/comment';
...

```

I'm using Symfony2 so on the server side all the urls are generated by the Router, and it bugs me that I use hardcoded urls in the js..

Is there a way to make them more dynamic?  

Those are the solutions I thought about but I'm **not** happy with:

* Defining them in the HTML tags like `<div data-url="<?php path('post_comment'); ?>">`
* Defining them in an inline script tag `<script language="text/javascript">...</script>`

I think that the urls in the js files of some big sites (SO, GitHub, etc.) are hardcoded, am I right?
