For event listening function should be global. Use preventDefault() to prevent submit to external. And you don't need method="post" in form tag. Some error on appendChild https://code.sololearn.com/W96nJD1Z1ij9/?ref=app

you could add a #id to the form and then add event listeners the form and prevent the default of the form and do the logic https://developer.mozilla.org/en-US/docs/Web/Events/submit

THE MOST SIMPLE ANSWER YOU CAN GET <html> <body onload="x()"> //This will call function x <script> function x() { alert("function x here"); y(); //this will call function y } function y(){ alert(" Why did you call me?"); } </script> </body> </html>

Ok, I managed to reach the function with: window.onload = function(){ var formSubmit = document.getElementById("formSubmit"); formSubmit.onclick = function addRow() { //Code to add new row } } But there is another problem. After the function finishes, the page reloads and returns to its non-modified state. How can I prevent it from reloading until the data are saved?
