RE: count characters on edit area

Well, this gets kinda difficult, as html stuff is normally "hidden" from sight, but would count as chars. If you want to count everything, including the html, it should be pretty easy. Check out some of the threads reguarding copying content from the iframe or setting content in the iframe.

Try this - copied from FCK API usage example and adjusted to serve as a button plugin, but can be executed via FCK.Commands(RegisteredCommandName).Execute();

var CharCountCommand = function (name)
{
this.Name = name;
}
CharCountCommand.prototype.Execute = function()
{
var oDOM = FCK.EditorDocument ;
var iLength ;
if ( FCKBrowserInfo.IsIE )
{
iLength = oDOM.body.innerText.length ;
}
else
{
var r = oDOM.createRange() ;
r.selectNodeContents( oDOM.body ) ;
iLength = r.toString().length ;
}

return iLength //number of characters
}
FCKCharCountCommand.prototype.GetState = function()
{
return FCK_TRISTATE_OFF;
}

Hope this is helpful.

RE: count characters on edit area

I find the solution. The sample code is:
editor_frame = document.getElementById(instanceName+'___Frame');
if (editor_frame!=null) {
editor_source = editor_frame.contentWindow.document.getElementById('eEditorArea');
if (editor_source!=null) {
oldcontent=editor_source.contentWindow.document.body.innerHTML;
if (oldcontent.length > maxlimit) {
editor_source.contentWindow.document.body.innerHTML=oldcontent.substring(0, maxlimit);
}
r = maxlimit - editor_source.contentWindow.document.body.innerHTML.length;
//if (r < 0) {
// alert("You have exceeded the word count, please decrease your words.");
//}
rem_field = 'document.page_fields.rem' + instanceName + '.value=\'Remaining: ' + r + ' characters\'' ;
//alert(rem_field);
eval(rem_field);
} else { return false; }
} else { return false; }

How do I apply this code?
In a javascript as a function I asume? And where do I have to set the maximum number of words?
Thx
