Attach event does not work - Need urgent help

Reply Quote

Hi Adam:

About the attachEvent.aspx page that you refered me to. IF you remove the attachEvent button and instead of calln the onclick event you link up this event with the body on load it does not work. We do not want to have a button tat user clicks to attach event..How can this be done.

That examle just show you how to attach your event to the editor. You don't need a button to attach it.

I've modified the example for you.

Here is the code:

<%@ Page Language="C#" %>
<%@ Register TagPrefix="CE" Namespace="CuteEditor" Assembly="CuteEditor" %>
<html>
    <body>
        <form runat="server">
            <h1>attach Event</h1>
            <hr/>
            <p>This example shows you how to attach/detach client events to customize the application.</p>
            <CE:Editor EditorWysiwygModeCss="style.css" id="Editor1" runat="server" ></CE:Editor>
        </form>
        
        <script language="JavaScript" type="text/javascript" >
        
        window.onload = function()
        {
            // get the cute editor instance
            var editor1 = document.getElementById('<%=Editor1.ClientID%>');
            
            //Get the editor content  
            var editdoc=editor1.GetDocument(); 

            // attach Event
            editdoc.attachEvent('onkeypress',HandleChange);
        }    
        
        
        function HandleChange()
        {
            // get the cute editor instance
            var editor1 = document.getElementById('<%=Editor1.ClientID%>');
            //Get the editor content  
            var editdoc=editor1.GetDocument(); 
            alert(editdoc.body.innerHTML);
        }    
        </script>
    </body>
</html>

Re: Attach event does not work - Need urgent help

Hi there

I need some urgent help with this too. I've pasted in the above code, but it's behaving very oddly. It's only working about 20% of the time. It works reliably the first time I run it. Thereafter it only correctly produces an alert once in a while.

Could this be something to do with the events loading in the wrong order - perhaps the CuteEditor isn't fully loaded when the window.onload event is picked up?

I have run the Error Console in Firefox on occasions when the code hasn't executed properly, and seen some funny errors like "editdoc.attachEvent is not a function".

Please could you get me some help on this asap?

Thanks!

Anna

Anns,

>>Could this be something to do with the events loading in the wrong order - perhaps the CuteEditor isn't fully loaded when the window.onload event is picked up?

Yes, you are correct.

Try the following code:

function CE_attachEvent()
   {
    // get the cute editor instance
    var editor1 = document.getElementById('<%=Editor1.ClientID%>');

    //Get the editor content
    var editdoc=editor1.GetDocument();
    // attach Event
    if(editdoc.attachEvent)
     editdoc.attachEvent('onkeypress',HandleChange);
    else if(editdoc.addEventListener)
     editdoc.addEventListener('keypress',HandleChange,true);
   }

Keep me posted

Hi Adam

Thanks for the speedy response.

This works well in Firefox - thank you. However, it doesn't seem to be doing anything in IE6. CE_AttachEvent fires correctly, and the function completes, but then the OnKeyPress event doesn't seem to generate anything.

Please could you help?

Also, I don't know if I'm doing the most sensible thing overall. I want a function that tells me when the page unloads whether the content of the CuteEditor has changed since the page was loaded.

Adding an event onKeyPress isn't really a great solution, because it fires every time the user presses a key, whereas I just need it to fire once. Is there an inbuilt CuteEditor property to check whether the content has been altered - an isDirty property (like in FCKEditor) or similar?

Thanks

Anna

Hi Adam

Thanks for this. Unfortunately, the page does not always work for me. In IE6, I see the following:

Works fine half the time.

The other half the time, the first press on attachEvent button does nothing, then a press on detachEvent followed by another press on attachEvent causes me to see a number of popups (somewhere between 3 and 9) everytime there is a keyPress event.

Can you repro this with IE? The page seems to load quite slowly, which probably isn't helping.

Works fine in Firefox 2, however most of my users will have IE!

My previous question - is onKeyPress the right event to use for my problem, where I just want to do a one-off check to see whether the content has changed when the user leaves the page? Is there a better way to do this, perhaps an inbuilt property of the editor?

Thanks

Anna

We will include this feature in the coming version 6.0.
