How to get leading plus sign while fetching value from a text field in adobe acrobat pro?

[Alex Doubts]

I want  to get leading plus sign while fetching value from a text field in adobe acrobat pro. I have typed (say +326777) in the text field, but on fetching the same, getting

326777 instead of +326777. I am fetching the text field data as below:

getField("txtNum").value;

Use valueAsString instead of value.
