I've been reading Nuxt.js's documentation on Plugins and the config nuxt file for adding scripts. I tried both, but no luck.

I'm trying to add the following code (located in `/static/js/scripts.js`):

```
 $(window).scroll(function(){
     if ($(window).scrollTop() >= 200) {
        $('nav').addClass('fixed-header');
     }
     else {
        $('nav').removeClass('fixed-header');
     }
 });

```

Can someone help me please?

In regular HTML usage, I just do the script tags before the closing body tag (for the sake of user experience). I was able to get the `scripts.js` to load in a Vue.js 2.0 framework, but once I moved everything to Nuxt.js, and tried to adapt it to Nuxt.js, everything else worked, except the `scripts.js` file.
