javascript on-load in HTML snippet

Hi all, I have seen this question pop-up several times and I have never seen a good, generic answer for this. This can be just me and I hope it is, but it keeps bugging me: How can I trigger javascript code after page load via the HTML snippet? As a sidenote, I need the DOM to be fully loaded, hence want to make use of the 'after page load' events. mx.addonload / $(document).ready etc. are not working for this, since Mendix and specifically the dojo library seem to block the pageload events for being called on. Now I am always building Custom Widgets for this, but this doesn't make sense in my opinion. Any help on this would be welcome!

Hi Ivo,

I’ve done functionalities like this in the htmlsnippet, and you should set the eventlistener to the window {

function myFunction(){
   // do something here

Hope this helps


Here is a solution with modern-day technology called jQuery.

Ever since the html-snippet has the option ‘JavaScript with jQuery’, you have the option to listen to the ‘document loaded’-event. See this code bit that sets focus to an input element that has classname ‘focusonme’:

$( document ).ready(function() {
let narcissus=$('.focusonme')[0]; //Obviously: add class 'focusonme' to the desired input
if (typeof narcissus !='undefined'){
    let myinput = narcissus.firstChild;
