Question

I have started using Dojo’s new on module to add my events. It works fine, but now I’ve run into a problem. When using keypress event I can’t seem to get the character value (for example “2” or “b”) from the pressed key. Previously I’ve used the behaviormodule, and the connect module, and then I have been able to get it by using e.keyChar or e.charOrCode, but now they´re undefined.

I have an event set up like this:

on(element, 'keypress', function(e)
{
    console.log(e.keyCode); //works, but not what I need
    console.log(e.charOrCode); //undefined
    console.log(e.keyChar); //undefined
});

How do I get the character of a pressed key when using this module?

In this case, I think what you want is to use e.keyCode in conjunction with the JS-native String.fromCharCode() in order to get the desired character value.

on(element, 'keypress', function(e) {
  var character = String.fromCharCode(e.keyCode);
  if (character === 'a') { // do a stuff } else { // do something else }
}
