Hi, I made a couple of changes to your script which I find improves performance when there are a large amount of words (600+) and also seems to help a bit with the ‘few words out’ bug.

The changes are to use a different technique for stripping html (use the browser itself) and to add a trim and a regex based split to the GetWordCount function. Relevant parts included below:

/**
* Takes the given HTML data, replaces all its HTML tags with nothing, splits the result by spaces,
* and outputs the array length i.e. number of words.
*
* @param string htmlData HTML Data
* @return int Word Count
*/
function GetWordCount(htmlData) {
return strip(htmlData).trim().split(/\s+/).length;
}

function strip(html)
{
var tmp = document.createElement(“DIV”);
tmp.innerHTML = html;
return tmp.textContent||tmp.innerText;
}

Where do I put the HTMl for the CKEditor instance? I’m using CKEditor with a Drupal module. Would it be different there? Thanks for the help. And thanks for this plugin. Hope it works, because it could be very useful. Thank You. Jeremy

I had an issue with destroying CKEdtitor instances — sometimes it would raise an error:
i.contentWindow is null
which, corresponds to ckeditor/_source/core/dom/element.js:1331:
return $ && new CKEDITOR.dom.document( $.contentWindow.document );

It turned out to be triggered by the Word Count plugin’s use of “setTimeout” and “getData”. The editor had been destroyed before the timeout triggered to run getData.

I hope this helps someone else!
