PDF forms - underlined variable text

Question

Hello Everyone,
I am trying to create a PDF form with variable text fields in Acrobat 9 Pro and I see there are very limited possibilities in the text formatting. I can specify font, size, color, border, but there is missing any option how to switch on the underlining of the text. Is there any way how to achieve this?
Thanks in advance for any hint.
Regards,
Jan

You can add some JavaScript to your script that imports the data from the database and format the inserted text by using the span object to apply the underline property. The following ecample is from the Acrobat JavaScript API Reference.
Example
Write rich text to a rich text field using various properties. See the Field object  
richValue property for more details and examples.
var f = this.getField("myRichField");
// Create an array to hold the Span objects
var spans = new Array();
// Each Span object is an object, so we must create one
spans[0] = new Object();
spans[0].alignment = "center";
spans[0].text = "The answer is x";
spans[1] = new Object();
spans[1].text = "2/3";
spans[1].superscript = true;
spans[2] = new Object();
spans[2].superscript = false;
spans[2].text = ". ";
spans[3] = new Object();
spans[3].underline = true;
spans[3].text = "Did you get it right?";
spans[3].fontStyle = "italic";
spans[3].textColor = color.red;
// Now assign our array of Span objects to the field using // field.richValue
f.richValue = spans;
