<h1>Example</h1> |
|---|
| 33 |
<p>For this example, try typing a capitalized character on each text field. You will see an alert that displays the |
|---|
| 34 |
character and the keycode corresponding to the key you pressed. |
|---|
| 35 |
And the keyCode is different when using Event.observe (With the patch the keyCode would be the same.)</p> |
