Syntax

JavaScript

function HDAnsGetRptNdx();

Return Value

Type: string
The repeat index of the current dialog. This will be a string in the form of "0:-1:-1:-1", where the index at each repeat level is separated by a colon, and -1 is used to represent unused levels of repetition.

Examples

The following example illustrates how JavaScript code running in a popup window (a "server answer source") can retrieve the current repeat index in the interview window from which it was invoked, and use that index to set repeated answers at the appropriate repeat index.

JavaScript

Copy

function SetVariables(index)
{
    window.opener.HDAPI.SetAnswer("Employee Name", EmpName[index], window.opener.HDAPI.GetAnswerRepeatIndex());
    window.opener.HDAPI.SetAnswer("Employee Gender", EmpGender[index], window.opener.HDAPI.GetAnswerRepeatIndex());
    window.opener.HDAPI.ScreenRefresh();
    window.close();
}
