How to use onsubmit() to show a confirmation if there are multiple submit buttons on the same form?

Answer 1

Here's an event-listener based solution that avoids inline event handlers (useful if your site has a Content Security Policy that forbids inline JavaScript):

HTML:

JS:

document.getElementById("deleteButton").addEventListener("click", function(evt) {
    if (!confirm("Are you sure you want to rollback deletion of candidate table?")) { 
        evt.preventDefault();
    }
});

document.getElementById("noButton").addEventListener("click", function(evt) {
    if (!confirm("Are you sure you want to commit the transaction?")) { 
        evt.preventDefault();
    }
});
