To create a custom script for encoding data for a paper forms barcode

In situations when you need to follow government or other specifications for encoding data, you may find that the preset data encoding options do not meet your requirements. Using the Custom option, you can provide your own script for encoding the data. The script could be quite simple, as in this example:

this.rawValue=NumericField1.rawValue

Alternatively, you could create a more complex script that determines which fields to encode based on certain conditions.

1.	On the form design, select the paper forms barcode object.

2.	In the Object palette, click the Value tab and deselect Automatic Scripting.

3.	In the Script Editor, you can modify the sample custom script or write your own script.

For example, the following sample code illustrates the JavaScript script required to retrieve a form’s field values, format a string representing a Comma Separated Value (CSV) instance containing the form fields, and update a paper forms barcode for an interactive PDF form. The form contains fields named accountNum, formerFirstName, formerMiddleInitial, formerLastName, newFirstName, newMiddleInitial, and newLastName.

// This function ensures that the barcode will update

// when a change is made to any field on the form.

function depends(node)

{

for (var i = 0; i < node.nodes.length; ++i)

{

var child = node.nodes.item(i);

if (child.isContainer)

depends(child);

}

}

// Return a field surrounded by quotes and followed with a separator

function fmtField(fieldName, separator)

{

var str = “\”" + fieldName.rawValue + “\”" + separator;

return str;

}

// Force all fields in the form to be updated in the dataset

depends(xfa.form);

// Generate the CSV string that will be encoded in the barcode

var comma = “,”;

var newLine = “\n”;

var s = fmtField(accountNum, comma);

s += fmtField(formerFirstName, comma)

s += fmtField(formerMiddleInitial, comma);

s += fmtField(formerLastName, comma);

s += fmtField(newFirstName, comma)

s += fmtField(newMiddleInitial, comma);

s += fmtField(newLastName, newLine);

// Assign the string to the barcode for encoding

this.rawValue = s;
