Export values and right-to-left radio buttons

Just a question.  Why does it matter what the export values are from the end user perspective, as long as the one selected lines up with the text of the form?

Well! Thanks, folks, but these answers leave me with more questions. 

 

exportValues[0] is the export value of the first widget of the field and exportValues[1] is the export value of the 2nd widget.

I appreciate that I'm asking a "why does Javascript behave like this" question, and this Acrobat forum might not be the place to ask. But: just wrapping the statement up in the "ray" variable, and operating on ray[i] instead of this.getfield(etc) works, but this doesn't:

this.getField("Is this thing on?").exportValues[0] = ["نعم"]
this.getField("Is this thing on?").exportValues[1] = ["لا"]

I'm happy to take my "why does Javascript do this?" questions elsewhere, but beyond that, I think that there may be something wrong under the hood, here.  I don't want to have to test for the values of "Yes" and "No" because my client's source English is full of "No." and "YES" and "No:" and other items that will fail the "replace A with AA" instruction.

Just change the order in which they appear in the array. 

But... they're already in the right order! exportValues[0] should be "Yes" in English. That's why I included this GIF showing me holding down the Shift key and selecting letters one by one by hitting the right-arrow key, demonstrating that the glyphs render in the console in logical order:

If the Console is respecting logical order when I'm working in it, but visual order when actually running what's on the Console, then I figure it's not working correctly. In general, when working with RtL raw text, I expect logical order to be respected. 

But it's not, even when wrapping the RtL text up in variables. If their position is supposed to be derived from their order of creation, then why are they reversing order when I insert RtL values? 

Just change the order in which they appear in the array. Move the Yes string to be the first in the array, and the No string to be the second one. I would actually strongly recommend to use variables for this, like so:

var yes = "نعم";
var no = "لا";
this.getField("Is this thing on?").exportValues = [yes,no];

The order in which the export values are applied is the internal order of the widgets, which is determined by their creation order. Their physical location on the page is not relevant.

The export values are in the widget order - the order the fields were created.  exportValues[0] is the export value of the first widget of the field and exportValues[1] is the export value of the 2nd widget.  Write a script that loops through the exportValues array and creates a new array that pushes the replacements into the new array.  Then set the exportValues with the new array.  I'll use A and B export values in a radio button called Group1, in this example, and replace them with AA and BB, since I don't know Arabic:

var ray=this.getField("Group1").exportValues;
var ray2=[];
for(var i=0;i<ray.length;i++)
{
if(ray[i]=="A"){ray2.push("AA")}
if(ray[i]=="B"){ray2.push("BB")}
}
this.getField("Group1").exportValues=ray2;

You can expand this script to loop through all fields and test the type for radio buttons, the apply the script to each set of radio button fields.
