Character counting and limiting

[Clement]

First of all, congrats for your work. WYMeditor is very easy to integrate and to customize.

I would like to use WYMeditors in my webapp but I have to find a way to count and limit the number of characters that the user can type ... sort of client-side validation, to avoid problem when insert data into database.
(It would be great to be able to configure it to count the number of characters of the formatted text (with html formatting) OR the unformatted one)

I used to have some javascript functions that were doing it well for "normal" text-area but doesn't work anymore with WYMeditor.

Did someone already tried to do it ? Does it seems easy to develop or not ? Could it be done in a plugin ?

Thx.
Clément

Hi,

Perhaps:

Code: Select all

jQuery(function() {

    jQuery('.wymeditor').wymeditor({
   
        postInit: function(wym){

            jQuery(wym._doc).bind('keydown', function(evt) {
                if(jQuery(wym._doc.body).html().length > 1000 //limit to 1000 chars
                  && evt.keyCode != 8  && evt.keyCode != 46 //backspace and delete
                ) return(false);
            });
        }
    });
});


The user will still be able to insert images, tables...
You should e.g. hide the buttons as long as the limit has been reached.

OK thank you for the tip. I'll try to do it later (not enought time those days). I'll post a feed back as soon as it will be done.
