How to register [removed] event

Question

I want to register keypress events for a document using javascript.

I have used:

document.attachEvent(\"onkeydown\", my_onkeydown_handler);


        

Answer 1

You are probably looking for:

document.body.addEventListener('keydown', function (e) {
    alert('hello world');
});​​​​​​​

But it is almost certainly going to be worth your time to use an existing library to abstract over the problems of the many browsers out there.

Please go through following links for detailed description.

https://developer.mozilla.org/en-US/docs/DOM/element.addEventListener?redirectlocale=en-US&redirectslug=DOM%3Aelement.addEventListener

In short, write handler as

function myFunction(e)
{
    ///For IE
    if(!e)
        e=window.event;

    // use e as event in rest of code.
}

You are looking for:

EDIT:

Javascript:

document.addEventListener("keydown", keyDownTextField, false);

function keyDownTextField(e) {
var keyCode = e.keyCode;
  if(keyCode==13) {
  alert("You hit the enter key.");
  } else {
  alert("Oh no you didn't.");
  }
}
