Question

I want to use jquery to limit the number of characters in an editable div (or form input).

Answer 1

This should work for you I think.

HTML

jQuery

$('#myText').keyup(validateMaxLength);

function validateMaxLength()
{
        var text = $(this).val();
        var maxlength = $(this).data('maxlength');

        if(maxlength > 0)  
        {
                $(this).val(text.substr(0, maxlength)); 
        }
}
