APEX_ITEM.TEXTAREA - character count limit

i want to set a character limit on a textarea. my initial thoughts were to use maxlength but sadly that is not available. Has anyone implemented this limit before?

dan,
unfortunately i cannot use that as the textarea is part of a report and i being created using apex_item.
marc,
thanks for the tip. i had tried to code it using onkeypress but my script was blocking ALL keys when the limit was reached. I didnt want to go down the route of specifying what keys to allow, backspace, delete etc.
Your link seems to do the trick.

Textarea character count feature quirk/bug

Apex 4.1.1.00.23
I've found a quirky thing about the textarea page item. The character count feature counts carriage-return-line-feed (CRLF) as one character, as you would expect it to, but it's stored as two characters in the database because of the way Windows handles new lines.
So, aside from using clob columns or explaining to users how Windows handles CRLF characters, any thoughts on how one might manage this quirk?

Create a Post-Submit Computation on the item that replaces CR/LF with LF...
replace(:p1_text_area, chr(13) || chr(10), chr(10))

Spry textarea character count not working in IE9

Hi.
I'm using DW CS5 for a ColdFusion form with a textarea field. The spry character count works in every browser but IE9. Anyone know how to fix this?
Thanks!

This feature will not work in IE9 and IE10.
The problem is two-fold
a) The Copyright notice shows 2006 as the last Spry update. This was around the time of IE7
b) Microsoft tends to go off on a tangent where every release of IE behaves differently
As always, we are in the hands of the Adobes and Microsofts.

Report TEXTAREA character counter

A textarea field has a "Maximum Width" and a Character Counter.
How can I create Character Counter for a textarea field in a report (SQL Query (updateable report))?

Denes,
My little bit different function: (one parameter less and no longer extra field for length in the select):
function f_set_counter(pConterID,pTextId,pMaxLength)
    var pLength = $x(pTextId).innerHTML.length;
    if (pLength>pMaxLength)
     {alert('Dit veld mag niet meer dan '+pMaxLength+' tekens bevatten.')
      $x(pTextId).value=$x(pBron).value.substring(0,pMaxLength)
      {$x(pConterID).innerHTML = pMaxLength}
    else
     {$x(pConterID).innerHTML = pLength}
}In the HTML Expression of the text field:
<textarea id="f06_#ROWNUM#" wrap="VIRTUAL" cols="80"
rows="5" name="f06" autocomplete="off"
onkeyup="f_set_counter('f06_#ROWNUM#_CHAR_COUNTER', 'f06_#ROWNUM#',500)"
#PA_AANTEKENINGEN#</textarea><br/>
<span id="f06_#ROWNUM#_CHAR_COUNTER"></span>
van
<span>500</span>
</div>
<script type="text/javascript">
f_set_counter('f06_#ROWNUM#_CHAR_COUNTER', 'f06_#ROWNUM#', 500);
</script>Now I do get the "0 van 500" on a new record.
Regards,
Rob

MaxLength="10" Character Count Limit in a Data Field

Hello,
Below is the syntax I'm using trying to get a data field ( MyField ) in my panel to have a maximum allowance of 10 characters.
This syntax is not doing anything to limit the count. Do you know what I have wrong in the line below?
<xmp_property name="MyField" category="external" label="$$$/Custom/Property/MyField Input_Label= My Field:" type="text" maxLength="10" ui:width="50%" ui:mru="true"/>

Hi Jacob,
here a short example with char and string.
DATA: ST TYPE STRING.
DATA: CH(250).
START-OF-SELECTION.
ST = 'I am a String with an % Character'.
SEARCH ST FOR '%'.
WRITE: / SY-SUBRC, sy-fdpos.
CH = 'I am a Char with an % Character'.
SEARCH CH FOR '%'.
WRITE: / SY-SUBRC, sy-fdpos.

APEX_ITEM.textarea with character count in a SQL Report

This seems like a simple question but where is the function to have APEX draw the textarea but with a maximum number of characters from within a SQL report.
I am building a parameter entry form but the number of parameters is dynamic so my best option was to use a SQL based report. I have looked though the APEX_ITEM package and found the textarea function but there is no options to draw the version of it that limits character count. Is there a way to have it draw that textarea instead of the unlimited one. In my case I have a length limit that I must enforce.

The only solution that comes to my mind is to use Javascript. Define a JS function in page header that will check the length of text in textarea and if it exceeds the limit then it will trim it.
Then, when creating textareas using APEX_ITEM add paramater onChange="callToYourJSFunction()"

How do I limit the character count in a text field?

I'm creating a form for co-workers to use when creating web content. I need to restrict their character count for items like headlines, titles, subtitles, etc. Any suggestions on a ready-made form to use out there? And how can I limit those fields so they don't generate content that will then need to be edited down?
Thanks,
EAW

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 w/character counter problem

Hi!
We use a textarea with character counter and limited its max width to 500 chars. If max 500 chars have been inserted, then input stops after 500 chars. That works fine in MS Internet Explorer. Even if you insert CR/LF inputs (ENTER button), the max number of typed in chars will not exceed 500. Using Mozilla Firefox, it is possible to insert many CR/LF, which increases the typed in number by 2. Thus you get e.g. "548 of 500" displayed beyond the textarea. After updating the page in IExplorer even here you get the same counter status displayed. As long as you do not type in the textarea field, the char counter remains as it is and the data can be submitted and finally stored in database.
Qu: Has anybody experienced teh same problem with max chars and CR/LF. Any idea of a workaround prevent "548 of 500" in textareas when typing in CR/LF ?
Br,
Thomas

The CharCount() function that is used by APEX should be updated to contain javascript code similar to the code described here:

A character counter in a TextArea

Our friend Mário is requesting the following:
"I would like to create a character counter in a TextArea with real time actualization, I only could do it after call an action (button), I would like that this happens in real time with the user typing and the counter being refreshed automatically."
If somebody can help him, please post.

Hi Mario,
what u would like is a Javascript function which monitors whitespaces and determines to add a counter for each line on the enter key
it would be activated onclick and on change of the control

Character counter in ABAp Webdynpro

Hi everyone,
I have a table with an editable field.
I'd like to have a "Character counter" over the table, which displays the remaining characters of the field.
Example:
The field length is 100, but there is a limit for the maximum length e.g 70. When the field is empty the counter is 70, if the user starts to type, after every character the counter is decreased, until the counter reaches 0.
My question is:
Is this possible? If yes then how? I can't find "onType" event in the Table properties
Thanks & Bye
N.

Hi,
The requirement looks very interesting...But I really wonder there is such event to handle the things as the user types the characters..There is no such event to handle this.. You need to have a button and everytime user has to click to increase/decrease the counter...check if TIMER UI element can be used in this case because to record the user inputs we can set the timer and then try to have the character count...But this is really not a solution. just try it out...
Let Thomas provide some inputs on this.
Regards,
Lekha.

Any way around the 393 character code limit?

Hi,
I'm using BI Publisher with Siebel 8.1.1.1.
I'm using the following to count the number of severity 1 Service Requests entered during the month of January:
<?count(ssServiceRequest[ssSeverity[.='1-Critical'] and xdoxslt:date_diff('d', xdoxslt:format_date(ssCreated,'yyyy-mm-dd','mm/dd/yyyy',$_XDOLOCALE,$_XDOTIMEZONE), '2011-01-31', $_XDOLOCALE, $_XDOTIMEZONE) <=30 and xdoxslt:date_diff('d', xdoxslt:format_date(ssCreated,'yyyy-mm-dd','mm/dd/yyyy',$_XDOLOCALE,$_XDOTIMEZONE), '2011-01-01', $_XDOLOCALE, $_XDOTIMEZONE) >=-30])?>
I now want to add another search criteria but it blows the 393 character code limit:
<?count(ssServiceRequest[ssSeverity[.='1-Critical'] and ssTrProductName[.!='WS-MService'] and xdoxslt:date_diff('d', xdoxslt:format_date(ssCreated,'yyyy-mm-dd','mm/dd/yyyy',$_XDOLOCALE,$_XDOTIMEZONE), '2011-01-31', $_XDOLOCALE, $_XDOTIMEZONE) <=30 and xdoxslt:date_diff('d', xdoxslt:format_date(ssCreated,'yyyy-mm-dd','mm/dd/yyyy',$_XDOLOCALE,$_XDOTIMEZONE), '2011-01-01', $_XDOLOCALE, $_XDOTIMEZONE) >=-30])?>
I have tried using an if statement to filter on the product name, but it is not working.
Any tips will be appreciated!
many thanks,
Claire

Try to insert a separate form field in your template where you should declare a variable and assign it the value of - xdoxslt:format_date(ssCreated,'yyyy-mm-dd','mm/dd/yyyy',$_XDOLOCALE,$_XDOTIMEZONE. Then call this variable in your existing form field.
This should reduce the code.

The character count in Messaging isn't there

I've got the character count option turned on in Messaging but I can't see it anywhere on the screen.

Character count appears ins SMS messages above the Send button once you've typed about 30 characters. It's in light grey so you may have missed it. It will never appear in iMessages because they have no character limit.

Character Count Variable

Hi,
Is it possible to set the 'chacters remaining' as a variable for Text area with c/count, this is because I have a comments field that is adding to a column that is already populated so the characters remaining will vary depending on what is already in the table
I know its set in the max width of the elemant section but you cant seem to put a variable name in there.
Thanks ANDY

hey andy--
you can't currently refer to session state values from the maxWidth field as you're finding. i've logged that as an issue, but you can work out your "characters remaining" request for now by calling our charCount jscript function from somewhere you can reference session state. to do so, take a look at the html that's generated when you use those "Textarea w/Character Counter" item types. you'll see that the form element has a jscript call in it that looks something like...
onKeyUp="javascript:charCount('P3_MY_TEXAREA',255,'tAreaCtr8','tAreaMax8','theBlock8');" onChange="javascript:charCount('P3_MY_TEXAREA',255,'tAreaCtr8','tAreaMax8','theBlock8');"
...and you'll see a div and span combo right after it that looks something like this...
<div style="font-size:8pt;visibility:hidden;" id="theBlock8"><span id="tAreaCtr8"></span> of <span id="tAreaMax8"></span></div>
...so you could put code similar to this into a regular TextArea item to call our charCount function while passing it the dynamic value. to do so, you'd put your div/span combo in the "Post Element Text" section of your TextArea item. you'd then want to call charCount by passing it the dynamic value. unfortunately, you can't just put that call into the "HTML Form Element Attributes" because that field currently doesn't support session state references. instead, you'd have to put in a call to a function of yours that calls our charCount. so a call like this...
onKeyUp="javascript:callCount();" onChange="javascript:callCount();"
...just worked in my test case. i defined my callCount funtion in the "HTML Header" field of the page-level atttributes screen as...
<script language="JavaScript1.1" type="text/javascript">
function callCount(){
charCount('P3_MY_TEXAREA',&P3_X.,'tAreaCtr8','tAreaMax8','theBlock8');
</script>
...and, as you can see, it just calls callCount while passing it my dynamic P3_X value instead of the fixed maxWidth one. having said all this, it's still our recommendation to not directly call the javascript functions that ship with htmldb. we reserve the right to change how those "internal" calls are implemented. to play it absolutely safe, you'd be better off to copy our charCount function into your app (presumably in a .js file) and call that copy using the same work around i specified above.
hope this helps,
raj

Character Count tracking

Is it possible to have a character counter visible for users to see and keep track as they complete a text field that has a maximum character set? Also, would it be possible to prohibit users from entering any additional text once the character maximum has been met?
Thanks!

Sorry we do not support these features for the HTML form format (the PDF form doesn't show the character count either but does prevent user from typing more chararacters after the limit is reached).
