HTML is different in javascript

I want to verify whether the user has modified contents in FCKEditor UI. So I am storing the values in hidden field. And I want to compare in javascript in client side.

But I am getting different content, so even if I am not changing, javascript is validation to false.

var oldText=window.document.frmTradeInstructions.Editorhidden.value;
var EditorWindow=htmlEditor___Frame.window.frames['eEditorArea'];
var newText= EditorWindow.frameElement.contentWindow.document.body.innerHTML;

if (oldText.length ==newText.length) always returns false when there are HTML Tags in the text.

Thanks for any help to fix this problem.

Is there a way to add an onChange handler to the hidden input field that FCKeditor uses?).

Then you could record the fact that the data has changed. Even if you get the length comparison working, that won't tell you if the user does something simple like fixing a typo.

You can use the IsDirty() call to check if the content has been changed as described in the release notes.

RE: HTML is different in javascript

I have drop down. User may change the content of the editor onChange of the Drop down. So OnChange I want to ask a confirmation message that, there is some change in the editor. And whether the user wants to save it or move to the next content.

So I am loading the contents in hidden field and to the editor. But again while verifying the javascript editor shows different content than the one assigned at the codebehind using Editor.value = "<BR>Testing 1234 <P> ABCD "

Thanks Alfonso for the help. I am able to solve this problem using IsDirty. This is how I fixed the problem.

dropdown onchange="var oEditor = FCKeditorAPI.GetInstance('htmlEditor');
if (!oEditor.IsDirty())
__doPostBack('dropdownName','');
else
if (!confirm('Text changed. Do you want to Continue and loose all the changes?'))
resetIndexes('dropdownName');
else
__doPostBack('dropdownName','')"
