Just include this in a script tag...

$(document).ready(function() {          
  $('ul#controls a').fontSizer();
$('#navigation ul.nav li ul').after('<span class="arrow"></span>');
//Limiting Comments to 150 characters for blog comments

var characters = 150; $(".TextAreaField").keyup(function(){ if($(this).val().length > characters){ $(this).val($(this).val().substr(0, characters)); alert("Comments cannot be more than 149 characters"); } var remaining = characters - $(this).val().length; if(remaining <= 10) { //change the color to red to warn user... $(".TextAreaField").css("color","red"); } else { //change back to original color... $(".TextAreaField").css("color", "black"); } });

});

The problem with that is that it may not always be 150 characters, and there could be multiple fields that have a length restriction.

So you attach cssclasses to them and say one of them is a150 another is a250 and another is a500. Then you just add these catches into the code. As long as your css classes are on the fields, then the js should handle the rest if you handle those if statements.
