Hopefully this is a pretty simple question! I've got the code working in jQuery to listen for a specific form on a page to be submitted and perform an alert when it is.. I.e.: The form itself doesn't have a name so I am targetting the form within a specific form ID.

$("#content form").submit(function() {
    alert("lorem ipsum dolor?");
});

What would be the syntax for performing this in javascript alone without using jquery? For example, I have this code (below) and just am unsure of how to listen for the form to be submitted to perform an action..

var submitform = document.getElementById("content").getElementsByTagName("form");

Thanks!
