Click a button programmatically - JS

Question

I\'ve seen this done in other webapps, but I\'m fairly new to Javascript and can\'t really figure this out on my own. I want to create a Google Hangout programmatically. How

Answer 1

window.onload = function() {
    var userImage = document.getElementById('imageOtherUser');
    var hangoutButton = document.getElementById("hangoutButtonId");
    userImage.onclick = function() {
       hangoutButton.click(); // this will trigger the click event
    };
};

this will do the trick
