How to limit the length of a text field in a dialog box (ADM)

Hi all

I need to limit the length of a field in a dialog box (ADM) edit_text, but char_limit doesn't seem to work, it's my code the problem ?

{
char_width: 8.
height: 100,.
item_id: 'Rete ',.
type: 'edit_text. "
Multiline: true,
char_limit: 5.
Width: 500,
}

If not, maybe I can use events to do the same thing with the onKeyStroke event but I don't know how to use the event in a dialog box (ADM) or if it is still possible...

Any idea?

Thank you for your help.

Phil

There are two events that can be used to check the length of the text,

The first is the action event for the text field, which is called when the field loses focus, it is a member of the purpose of dialogue with the same name as the item_id.  This event could also be used to update another field in the dialog box that indicates the number of characters, you may even have a small picture of alert which becomes visible to make it obvious that there is a problem.

The other event, as already mentioned, is the validate event.  This allows to block the exit from the dialog box and display a popup to alert to the user.

You will find some examples of dialogs here:

Take a look at the pages resize tool dialog box.  It will give you some ideas of what can be done.

There is a plug-in Acrobat for creating dialogs here:

It's a Visual drag and drop Editor.  You can download and use for free for 10 days.

  • How to limit the length of the texts on iOS9?

    Hello

    I just worked on why I am required by my mobile / cell phone provider EA.  They charge any text as a picture message / SMS, it is longer than 120 characters?  Does anyone know how to limit the length of the texts / SMS so that it is impossible to send a more 120 characters or create an alert so that you are aware of the number of characters in the text / sms?

    Thank you very much

    Hello Turnus123,

    Thank you for using communities of Apple Support.

    I see that you will have to pay for SMS more than 120 characters.  To help identify messages exceeds this amount, you can activate a number of characters in the message settings.  Simply go to settings > Messages and activate "number of characters".

    Take care.

  • How to increase the length of line comment fields

    Hello

    as requested by a customer, we need to know if it is possible to increase the length of line comment fields.

    In fact, the size is:

    for allergens/intolerances/additives comment field-> DB limit = 256 characters; Web = 125 character limit

    for field nutrient comment-> to the defined benefit limit = 512 characters; Web = 250 characters limit

    We need to increase both limits up to 1000 characters.

    I hope my question is clear.

    Thank you and best regards.

    Michele

    Hi Michele,

    You can increase the size of the field or the size of the text for the field of comment allergens/intolerances/additives by following steps:

    1, go to \Web\gsm\BaseForms\UserControls\ctlComplianceContainedGrid.ascx, open the file

    2, go to line 102:

    3, edit theCellRepresentation.getTextareaCellEditor or the width of the field, save the file, refresh your page open or create a new page, then this field will change to the newly configured size

    Notes: the maxinum supported text is 4000 characters

    Unfortunately, the comment nutrient field do not support 256 characters. I suggest that submit you an improvement if it necessary business.

    I hope this helps.

    Thank you

  • How to set the input to a text field filter?

    I use a text entry (a flash component) to which the user will enter numbers only in (positiv and negative integers and floating point numbers) but not any other symbol.

    Copy the following code


    on keyDown me

    If ("1234567890 -") contains the key or the key = backSpace or key = tab keyCode = 123 or the keyCode 124 = then
    Pass
    on the other
    stopEvent
    end if

    end

    This script works fine when I use it with style text old fields to the Director. It does however not work with new component flash style (text entry).

    How can this be repaired?

    Thanks in advance for any help.

    HUMAN RESOURCES


    First of all, I should mention that I have avoid using Flash inside Director, so there may be a better way.

    As you noted, catch events keyDown globally affect all entrances to the keyboard. If you want to specify a subset of sprites so you need a management system which. The simplest would be a global list that fill you it with a small number of sprite when switching to a new framework.

    global gRestrictedInputSprites

    on preparemovie
    gRestrictedInputSprites = [1, 5, 6, 23] - SAMPLES
    keyDownScript = "chatchKeys()".
    end


    on stopMovie
    keyDownScript = «»
    end


    on chatchKeys
    If gRestrictedInputSprites.getPos (_movie.keyboardFocusSprite) then
    If _key.key = "," and then
    stopEvent()
    on the other
    Pass
    end if
    on the other - overall restrictions on entry
    Pass
    end if
    end chatchKey

    And then add a beginsprite to your Framescript to set the values of the gRestrictedInputSprites for each image tag loop you on--assuming that you place the frame head with "go the frame."


    global gRestrictedInputSprites

    on beginSprite me
    gRestrictedInputSprites = [] - the list of sprites all entry who need entry restrictions for this frame.
    end

    on exitFrame me
    go part
    end

    If you follow this path then I suggest to use a GPDL to set the sprite shortlists. No need to write more than one behavior.

  • Limit the length of the text to a fixed length

    The field is the invoice number on a doc to check to RTF. If the field Bill encapsulates, it moves other objects on the control document and verify the cause of big problems printing.

    Is there a way to limit the length of a text field to an actual length printed on the document? Or prevent the area of packaging? IE just trunc it to a fixed length?
