I think you can use the PluginAPI `onPageChange` function to do what you are looking for. See: [Using the JS API](https://meta.discourse.org/t/using-the-pluginapi-in-site-customizations/41281)

Here’s an example function:

```js
<script type="text/discourse-plugin" version="0.8">
    api.onPageChange(() =>{
        randBackground();
    });
    
    function randBackground() {
        $('body').css('background-color', '#'+(Math.random()*0xFFFFFF<<0).toString(16));
    }
</script>

```
