I have a .js file that is the javascript translation of a java file.jar. I would like to run the file as soon as the HTML page is loaded. Is it possible? now the file is run using the following code

 <div class="w3-twothird" align="center">
       <script>
           cheerpjInit();
           cheerpjCreateDisplay(500,400);
           cheerpjRunJar("/app/tesi/homepage/disgrafia.jar");
       </script>
       </div>

I'd like to use only the js file and not the jar.

The simplest way to run a piece of code once a site has loaded is using jQuery's ready() function. Goes something like this

    $(document).ready(function()
    {
//Do the whatever you need to here
    });

Do keep in mind, however, that you will need jQuery on your page. Simplest way to get it is using CDN. Just paste this in your <head> </head>

<script
  src="https://code.jquery.com/jquery-3.4.1.min.js"
  integrity="sha256-CSXorXvZcTkaix6Yvo6HppcZGetbYMGWSFlBw8HfCJo="
  crossorigin="anonymous">
</script>

EDIT: If you don't want to use JQ, you can use an event listener for when the page loads, like so:

document.addEventListener("DOMContentLoaded", function() {
    // Code to be executed when the DOM is ready
});
