How to prevent default on form submit?

Question

If I do this I can prevent default on form submit just fine:

document.getElementById(\'my-form\').onsubmit(function(e) {
   e.preventDefault();
   // do some         


        

Answer 1

i known this is old, but just for the sake of it. try

document.getElementById('my-form').addEventListener('onsubmit', 
function(event){event.preventDefault();my_func();});
var my_func = function() {
// HOW DO I PREVENT DEFAULT HERE???
// do something
}
