Trying To Populate a Text Box with Export Values from Multiple Selections from a Dropdown List Box

[melb2]

Hello,

I am trying to poplulate a textbox with the export values from multiple selections from a Dropdown List Box. For example, my dropdown list box may have:

Item Value/Export Value:

Posting Journal Entries to General Ledger/F_GL_POST

Budget Adjustment Entry/F_BD_ENTRY

etc.

I want the user to pick from the descriptive terms (the Item Value in the Dropdown list), but have the more technical description (the Export Value) poplulate in the text box. The user picks as many Item Values as they need one at a time. If they pick one they don't need, they pick it again and it is removed from their selections. I found a DOCUMENT LEVEL script online that works for this EXCEPT that it provides the Item Values rather than the Export Values. I need the Export Values in the text box, not the Item Values.

Here is the script:

function fillRoles(doc, fieldName, newValue)
{
    var ar = [];
    // Get the value(s) currently stored in the dropdown value and 
    // convert them to an array
    var v = doc.getField(fieldName).value;
    if (v.length > 0) {
        var ar = v.split(",");
    }
    // Do we already have newValue in the array? 
    var foundIt = -1;
    for (var i=0; i<ar.length; i++) {
        if (ar[i] == newValue) {
            foundIt = i;
            break;
        }
    }
    if (foundIt != -1) {
        // remove the item
        ar.splice(i, 1);
    }
    else { // add the item at the end
        ar.push(newValue);
    }
    // convert the array to a string
    this.getField(fieldName).value = ar.join();
}

 After I added the document level script, I added the following code to the dropdown list on the Validate tab under the 'Run Custom validation script':

fillRoles(this, "textbox name here", event.value);

I am trying to figure out what I need to change to display the export values rather than the Item values.

Thank you.

You can read everything you need to know to solve this issue in the Acrobat JavaScript Reference, and in the articles posted here:

https://www.pdfscripting.com/public/List-Field-Usage-and-Handling.cfm

Given the material at these sites, there is a simple and obvious solution. Delete the code in the validation Script, and then add this line to a custom Keystroke script on the Dropdown.

if(!event.willCommit) fillRoles(this, "textbox name here", event.changeEx);

OK, thank you. I've  made the change that you suggested. However, now the results in the textbox are BOTH the Item Value and the Export Value.

For example,

F_GL_POST,Posting Journal Entries to General Ledger,F_BD_ENTRY,Budget Adjustment Entry

What I need is:

F_GL_POST, F_BD_ENTRY  (hopefully with a comma and a space like this, not just a comma)

Did you remove the validation script?

The only way the item value could be there is if the other script was also being run. So get rid of it.

Ugh. Yes, I did and checked that it was gone. However, I must have had an undo in the interim that undid my delete at that spot too. I re-deleted it and it is now working. Thanks very much!

What change i need for adding the export value wih a new line each time and remove them with new line each time ? (join function? or splice function?). 

Eagerly waiting for a response!!!!

Thank You
