I would like to hook the keydown event in the TinyMCE Editor on the edit post admin page. I managed to hook the HTML content editor using the following code:


Here is my failed attempt at hooking the TinyMCE editor. The problem is that the editor hasn't been init yet so the variable ed is undefined.

var ed = tinyMCE.getInstanceById('tinymce');
ed.onChange.add(function(ed, l) {

Any help would be much appreciated!

Your custom TinyMCE code should go inside a TinyMCE plugin, check some of the related links(to the right of this page) for examples of how this is done. – t31os Jul 26 '11 at 14:56

the TinyMCE Editor has its own keydown event handler and its hooked to a function on initiation so to do that you can create a tinymce plugin or use the wordpress initiation of it with tiny_mce_before_init hook like this:

add_filter( 'tiny_mce_before_init', 'wpse24113_tiny_mce_before_init' );
function wpse24113_tiny_mce_before_init( $initArray )
    $initArray['setup'] = <<<JS
[function(ed) {
    ed.onKeyDown.add(function(ed, e) {
        //your function goes here
        console.debug('Key down event: ' + e.keyCode);

    return $initArray;

Thank you! That's exactly what I wanted to do. The only stuff I could find was using the tinyMCE init to create new editors with event handling. Using tiny_mce_before_init worked perfectly. Thank you so much. – odie5533 Jul 26 '11 at 16:39
