Javascript: Onclick/onsubmit For Dynamically Created Button

I dynamically create a button in the way I found in the Internet: Page = function(...) { ... }; Page.prototype = { ... addButton : function() { var b = content.d

Solution 1:

var foo = function(){
  var button = document.createElement('button');
  button.innerHTML = 'click me';
  button.onclick = function(){
    alert('here be dragons');return false;
  };
  // where do we want to have the button to appear?
  // you can append it to another element just by doing something like
  // document.getElementById('foobutton').appendChild(button);
  document.body.appendChild(button);
};

Solution 2:

Here is a version with attributes for input:

 <button onclick="myFun()">Add More</button>
    <script>
        function myFun() {
            var x = document.createElement("INPUT");
            x.setAttribute("type", "file");
            x.setAttribute("id", "file");
            document.body.appendChild(x);
            x.onchange = function () {
                hello();
            };
            btn.appendChild(t);
            document.body.appendChild(btn);
        }
        function hello() {
            window.alert("hello!");
        }
    </script>
