MDelcour I need to set a word count limit for the excerpt so users can't type more than 40 words in the excerpt. Do I need to create a new custom text area type that can be used in addition to 'Normal,' 'Rich' and 'Teeny Rich'?

This kind of functionalities doesn’t work in rich or teeny textareas, but works fine in normal textarea. Take a look at this tutorial achieving this.

Ok, I’m back and that worked perfectly. I took it a step farther and added a character count in the help text by adding a line to the example jQuery. Now, in addition to the character limit, user see how many characters they have left. feel free to add this to the example doc as it is already very useful.

Help text:
Brief description to describe the post. <span class="excerpt-char-count">400</span> characters remaining.

jQuery

//Text Limit for WPUFE
function wpufe_limit_text() {
   
  if ( is_page('test') ) {
		?>		
	    <script type="text/javascript">
	        (function($) {
	 
	            function limitText(field, maxChar){
	                var ref = $(field),
	                    val = ref.val();
	 
	                if ( val.length >= maxChar ) {
	                    ref.val(val.substr(0, maxChar));
	                }
	            }
	 
	            // Insert Limitations here
	            $('#post_excerpt').on('keyup', function(event) {
	                limitText(this, 400);
	                $( ".excerpt-char-count" ).html( 400 - $(this).val().length );	                
	            });

	        })(jQuery);
	    </script>
		<?php
	}
}
add_action( 'wp_footer', 'wpufe_limit_text' );
