adobe acrobat form texbox value direction

[Maalshennawi]

I need a script to change the textbox value direction to right to left or left to right as the language in the  dropdown list i used the script below and the alignment worked useful but the direction is not working:

// Get the language from a dropdown or text field
var language = this.getField("lang").value;

// Get the text field
var textField = this.getField("Textbox");

// Set the direction based on the language
if (language === "ARABIC") {
textField.alignment = "right";
textField.direction = "rtl"; // right-to-left
} else if (language === "ENGLISH") {
textField.alignment = "left";
textField.direction = "ltr"; // left-to-right
}

Form text fields doesn't have a property direction.

They do, actually, but it can't be set using a script, only manually.

If your application has the RTL options enabled (under Preferences - Language) then you can set a field's direction as Right-to-Left or Left-to-Right, via its Properties, under the Appearance tab:

I make this form for other users and I will lock any edits in the form so I need it in javascript

[try67]

I don't understand how these two things are related, but as I said, it can't be done in JS, so you need to do it manually.

Ah, I see what you mean now, but it can't be done. As Bernd suggested, create two fields with the correct Direction option pre-selected and make them visible/hidden based on the user's selection.

Do you mean if I have 100 Fileds I should duplicate them in the form and the code

the script is working useful with HTML why is it not working in the PDF form

Yes.

> the script is working useful with HTML why is it not working in the PDF form

Because HTML and PDF are not the same thing.

textbox option includes directions and I can change it manually but I need it in javascript 

[Bernd Alheit]

Use two fields with different directions and show/hide the fields in the script.
