Use of javascript and textarea with HTML editor

Hi all,
I have been trying to use some onchange javascript in the HTML Form Element Attributes of an item which is a textarea with an HTML Editor. It just seems to ignore the code. When you "view source" the code does not seem to be there.
What I am attempting to do is described in thread: detecting changes to items prior to submitting page
i.e. to warn a user that if they leave the page without saving they will lose their changes. It works fine with most of the other items on the page i.e. text boxes, select lists but not the textarea with html editor.
Is there somewhere else I should be putting my js for items of this type? I have spent some time looking through the forum posts but cannot find an answer so far.
Thanks,
Brian

I'm having the same problem.
Would like to use the onChange event in a textarea with html editor.
This works in Firefox (where I don't get the html editor but only a textarea) but doesn't seem to work in IE.
Is there another way of detecting the user has changed the text in the html editor?
Thanks,
Pieter

  • APEX - Spelling check and textarea with html editor

    I have an item on the form defines as textarea with html editor. I also need to be able to do spelling check, but the "textarea html editor" only has font features and no spelling check. Is there away to define an item to have both spelling check and font features in APEX? Any response is greately appreciated.
    Thank you,
    MT

    MT,
    No, this is not a supported region type in APEX 3.2.
    You can take a look at jQuery and the number of rich text editors available for it: http://www.queness.com/post/212/10-jquery-and-non-jquery-javascript-rich-text-editors
    Hope this helps.

  • Custom Popup - Passing values back to Textarea with HTML Editor

    I have created a Custom Popup which is to populate a "Textarea with HTML Editor".
    I have found that the Custom Popup works fine if the target item is defined as a "Textarea", or "Textarea (auto-height)", or "Textarea w/Character Counter" (although the counter is not automatically updated), or "Textarea w/Character Counter & Spellcheck", or "Textarea with Spell Checker".
    However, if the target item is defined as "Textarea with HTML Editor" the Custom Popup does not populate the target item. No error message is produced. If the target item already had data, the data is unchanged.
    Is this a known bug?

    "Textarea with HTML Editor" is actually two objects on the screen with javascript keeping the data in the two objects in sync as you type in the editor.
    You have to populate both objects as you try to syncronize the data from your popup.
    I built a screen using dHTML that switches between the HTML Editor and the Text with Spell check and use Javascript to keep the two (actually three objects in sync)
    My button that switches from one view to the other uses the following syntax:
    javascript:setEqual('P9904_HTML_MESSAGE','P9904_MESSAGE','P9904_MESSAGEDiv');
    'P9904_HTML_MESSAGE' is the HTML view of the data with spell check
    'P9904_MESSAGE' is the html editor view of the data
    'P9904_MESSAGEDiv' is the extra object that Oracle uses for the editor
    This is the fuction that keeps the data in sync:
    function setEqual(fromObjectID,toObjectID,htmlObjectID)
    document.getElementById(toObjectID).value = document.getElementById(fromObjectID).value;
    document.getElementById(htmlObjectID).innerHTML=document.getElementById(fromObjectID).value;
    I hope this helps.

  • Textare with character counter versus textarea with html editor

    Hi
    I am using a textarea with html editor. I need to restrict the user to not type more than 25000 characters? Can someone tell me as to how I can do that?
    I know that one can set the maximum width for textarea with character counter and it prevents one from typing in more than the maximun specified, but I really need to use the html editor. Thanks.
    suni

    This is caused by the charCount javascript function, which dynamically sets the text colour to 'red' when the maximum number of characters is entered, but "resets" it to 'black'.
    Guess the way to avoid this is to create your own equivalent of the charCount function that captures the actual colour from the DOM and attach it to a textarea using the onchange and onkeyup attributes used in the built-in one.

  • Textarea with HTML editor is not working

    Hi all,
    This is producing me a real headache.
    I created the simplest application in the world with one Textarea with HTML editor, and the editor control does not show the usual tool bar for fonts, color, alignment, etc. Just a ordinary textarea.
    Moreover, this was working before... I moved to another location in my work (me, not the server). Yes, I thought about the Internet Explorer, but Firefox has the same issue.
    So any idea I can try to make this work?
    I have another applications already in production with the same issue.
    Need help!!!!!!!!!
    Thanks in advance.

    Lukas,
    I would go and integrate FCKEDITOR (http://www.fckeditor.net/ ) into your application.
    Here are instructions on how to achieve this (sorry but only in German):
    http://www.oracle.com/global/de/community/tipps/einbinden_fckeditor/index.html
    It basically means:
    1) copying the files from fckeditor under the /images directory
    (you can use the instructions here: http://daust.blogspot.com/2006/03/where-are-images-of-application.html)
    2) creating two shortcuts INCLUDE_EDITOR_SCRIPTS and EDITOR
    3) placing the shortcut INCLUDE_EDITOR_SCRIPTS into the page html header and
    4) placing the shortcut EDITOR into the post element text of your plain textarea element
    That's it.
    BTW, FCKEDITOR has been included in Apex 3.0 as a standard item type.
    Regards,
    ~Dietmar.

  • APEX - Textarea with HTML Editor.

    All,
    I am working with Application Express Version 2.2.1.00.04
    I have the following problem:
    I have an item "Textarea with HTML Editor" which I am inserting
    information CLOB in a table.
    This data is consulted by a Region Report of APEX which has a Link that
    will be a popup. Inside the report, I use wwv_flow_utilities.URLENCODE
    (here the column is a CLOB) where it gives me the error "ORA-06502:
    PL/SQL: numeric or value error: character string buffer too small".
    I started to investigate which might be the problem and saw that the
    item "Textarea with HTML Editor" usually inserts special characters.
    I show an example of the special character that inserts and which is the
    error.
    SELECT wwv_flow_utilities.URLENCODE(' ')
    FROM dual;
    This character, which is like a space in target, is bringing problems to
    be able to execute the report.
    A provisional solution to solve this problem is to put a REPLACE into
    the Query.
    Has anyone this problem.???? Do you know why this character can be
    inserted??????
    Thx..

    Thanks Dimitri!
    I'm trying to find this place in the application but I don't have enough privileges. Here, we are working with Application Express 2.2.1 and we have to upgrade to 3.1.1.
    In order to improve the behaviour of HTML Editor Standard, I think we should integrate FCK to our application, do you know about any step by step explanation to achieve this? Because I was searching this information in the forums, but I can't find anything. Please, any information you can share with me will be very helpful
    Thanks again!

  • Changing the font size does not work with Textarea with HTML Editor

    If you change the font size in the text area of a "Textarea with HTML Editor" item it does not work. I've searched the forum and the only solution I've seen is to use an HTML editor foriegn to APEX. Does anyone have a better solution? Thanks, Elizabeth

    I'm having a similar issue except with HTML Editor Standard.
    What I'm doing is allow someone to write to an HTML Editor Standard field and then an HTML marked up text is saved to a db CLOB column. In another page, I reference this DB column and show it in an HTML Region (I do a computation Before Regions for a hidden item that writes out the html with "htp.p")
    Everything shows up fine EXCEPT the font tags and headings. I'm finding that the HTML Region sets the font size only with the < d i v s t y l e="font-size: large" >and NOT < f o n t size:6 >. When the HTML Editor renders the user's text input, any size changes are made with the < f o n t > tag, which is depreciated anyways, and not with "style". That's why the size is not showing up.
    I can't really figure out why the headings aren't showing up except maybe the css style in the region is overridding it...
    Is there another APEX item type like HTML Editor (which uses FCKEditor) that I can use, or maybe another approach to remedy this issue? Or maybe this post calls for an enhancement with the HTML Editor?{size}{size}

  • Printing the data in "Textarea with HTML editor" item in APEX as pdf

    Hello,
    I have a requirement which goes like this.
    The user enters data in the HTML editor in APEX. All the tools available in the HTML toolbar will be used (eg. bulleted points, tables etc.). This data is stored in a single cell in the database. This data needs to be generated as a pdf for printing. We have Apache FOP installed as well.
    When I try to create a report region with this data and export it as pdf, the html tags are not considered. For eg. the table in the HTML editor doesn't appear as a table in the pdf, only the text appears.
    Let me know if such a transformation is possible. Also, can any other tool perform this??
    Note: The data in the HTML editor may not be in a fixed template. Whatever is entered there has to be converted.
    Thanks in advance !!

    The strip HTML attribute is set to "No" already. If you understood clearly, I need to convert the entire data in a HTML editor item to pdf. The data is stored in a single cell as HTML tags in the database. The data may inturn contain HTML tables as well. These HTML tables are not captured in the pdf, only the text within the tables are displayed.

  • How can I use javascript in a Text Area with HTML editor??

    My question is... how can I use javascript in Text Area with HTML editor??
    I can use javascript functions that change the content of Text Areas but i can´t if i try in text area with html editor....
    I need to limit number of characters in a text area with html editor and i can´t.
    could anybody help me please?

    I have been experiencing similar problems with the HTML Editor and have managed to find an answer that should start to answer some of my questions. The Apex HTML Editor Standard is actually an HTML editor called FCKeditor. The FCKeditor has a Javascript API that can be found at http://docs.fckeditor.net/FCKeditor_2.x/Developers_Guide/JavaScript_API. Unfortuately this doesn't seem to give the whole answer and I found more at http://www.houseoffusion.com/groups/cf-talk/thread.cfm/threadid:49607.
    I needed to get the text entered within my html editor standard (e.g. P1_MYTEXT) and use it within my javascript function. I did this by using the following script
    <script language="JavaScript" type="text/javascript">
    function showtext(){
    var oEditor = FCKeditorAPI.GetInstance('P1_MYTEXT');
    var editortext = escape(oEditor.GetXHTML(oEditor.FormatOutput));
    alert(editortext);
    </script>
    Hope this helps.

    Thank's

    In the raise event you can pass the value
    like below.
    <SCRIPT>
    function raiseEvt(value1){
    if(window.document.domain == window.location.hostname){
    if ( document.domain.indexOf(".") > 0 ) document.domain = document.domain.substr(document.domain.indexOf(".")+1);
       EPCMPROXY.raiseEvent( "urn:com.sap:BWEvents","BWiViewevent", value1, null );
      // alert('tree domain'+document.domain);
    </SCRIPT>
    and in the
    subscribe event you can get the values like below.
    <script language="javascript">
    if(window.document.domain == window.location.hostname){
    document.domain = document.domain.substring(document.domain.indexOf('.')+1);
        EPCMPROXY.subscribeEvent("urn:com.sap:BWEvents","BWiViewevent", window, "myreceiveEvent");
    function myreceiveEvent( eventObj ) {
          document.forms[0].gp_hidden.value = eventObj.dataObject;
    </script>

  • Can you change the units used for size and position in layout editor?

    Hello,
    In Aperture 3.4, does anyone know if you can change the units used for size and position in layout editor?  The page is set in inches, but the image size and position are given in centimetres and I would prefer to work all in inches to create custom layouts.  I can't see any way to change this.  If anyone knows how it would be much appreciated.  Thanks!

    Aperture uses the unit settings defined in the System Preferences.  Set the "Measurement Units" in the "Region" tab of the "Language & Text" preferences to "US"; the Aperture will display the Size & Position in inches, if it is the "Book" layout manager you are asking about.
    Merry Christmas!
