how to create a form without a submit button javascript

//you have to have the form tag in this format 
<form id="myFunction" onClick= { myFunction } >
 <input type="file" name="fileToUpload" id="myFunction" />
</form>

//from there you would have to create a function 
function myFunction() { 
          document.getElementById("myFunction").submit(); 
        }
//if this does not work, start to pray lol and do a lot of digging in 
//the browser, good luck !
