I have a custom panel widget that needs to run some javascript/jquery in order to upload a file while staying on the same page. It works just fine when I login to the panel then upload a file. But when I navigate to anywhere in the panel then come back to the dashboard, the script won’t run again until I reload the browser. I have the script wrapped in `$(document).ready(function() {...` in the widgits/widget-name/template.php file, but that doesn’t seem to help after panel navigation. ---

How do you trigger the script? Is there an upload button with an event handler? ---

The issue here is that the JavaScript is only executed once after you loaded the panel. After then Kirby 2 does not make “hard” requests anymore and just loads the view via JSON which contains a string of html. Depending on your knowledge and browser setup I’ld suggest to make use of a [mutation observer](https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver). Using this API you can listen to added or removed DOM nodes, attribute changes and fire a callback to reinitiate your JS. By the way I faced a similar issue in my [kirby-analytics-dashboard](https://github.com/gearsdigital/kirby-analytics-dashboard) Plugin. I found a [quite hacky way](https://github.com/gearsdigital/kirby-analytics-dashboard/blob/master/assets/js/Helper.js#L12) 🙈 ---

@texnixe that’s exactly right. Edit: sorry the picture text is so small. Basically the form submits to my dummy url ("?") if the JS hasn’t been attached and run preventDefault() on the form. ![Screenshot_2019-06-18_15_23_36](https://europe1.discourse-cdn.com/flex017/uploads/getkirby/original/2X/b/bd924af79f1a75a856605a362fc2db43eff177a5.png) @gearsdigital this makes total sense. I had no idea the Kirby 2 panel was an SPA. With the mutation observer, would I just look for the existence of a unique div#id that only appears in my widget on the Dashboard? Then re-attach the event handler if that div#id is present? ---

That is what I’ld do 🙂 A made a quick fiddle for you… [https://jsfiddle.net/e5hk8ma3/](https://jsfiddle.net/e5hk8ma3/) ---

Thanks so much @gearsdigital. I used the fiddle, added a flag to prevent multiple firings (because for some reason the mutation observer fired multiple times), and it works a beauty! ---
