Cannot chek if there is no text with JS

Hi all.

I'm using your wonderful tools. Really good.

My only problem for the moment is I can't check the FCKeditor value with JavaScript.

I have to check if the user let empty the text of the editor but, cause the input is 'hidden', I can't use the JS check

if obj.FCKeditor.value.lenght==0

How can I check if nothing is written in the editor?

Thank you a lot.

RE: Cannot chek if there is no text with JS

Hi, in past versions I was able to check by using this function and passing in 'instanceName___Frame' as the ed_name parameter:

function getfck(ed_name){
if (document.all) return (document.all[ed_name].contentWindow.document.all['eEditorArea']).contentWindow.document.body.innerHTML;
else if (document.getElementById) return (document.getElementById(ed_name).contentWindow.document.getElementById('eEditorArea')).contentWindow.document.body.innerHTML;
}

Then I test the returned value to see if it's empty or not. But since version 2.3, I've been getting JS error messages saying 'contentWindow' is null or not an object.

Does anyone know why? Thanks!

Yes it would really appreciated some help.

I need absolutely to check the value via JS.
Or at least I need a function that can retrieve the value and pass it to a JS check function.

I'll try this code, but as you said I fear it won't work on my version

Please developers!! Help Us!! :>

Thank you!

RE: Cannot chek if there is no text with JS

pictor, I was seeing some other forum posts and this should work:

function fck_filled(ed_name){
if (FCKeditorAPI.GetInstance(ed_name).GetXHTML() == "") return false;
else return true;
}

if (!fck_filled('description')) alert('The editor is empty');
else alert('The editor has something in it');
