Javascript API - Select marks in a dashboard with multiple worksheets
I have a dashboard with one worksheet at the top that gets marked to filter the worksheet below to display the flights. I use an outside control (not in tableau) to search for flights and use the javascript api to select those "Flight Records" in Tableau.
When flights selected (outside of Tableau), then do the following:
var activeSheet = this.m_workbook.getActiveSheet();
if (activeSheet.getSheetType() == "worksheet") {
activeSheet.selectMarksAsync(
"Flight Record",
newFlights,
"replace"
);
} else if (activeSheet.getSheetType() == "dashboard") {
var sheets = activeSheet.getWorksheets();
for (sheet in sheets) {
sheet.selectMarksAsync(
"Flight Record",
newFlights,
"replace"
);
}
}
The problem is that even though the first worksheet doesn't contain "Flight Record" to select, it tries to set the marks, and since it doesn't find "Flight Record", it clears the filtering.
Is there any way in the javascript API to find out what the marks data will contain when no mark has been selected? What I thought I could do is look at the marks for a worksheet, see if "Flight Record" is a field, if so, then I could perform the selection on that worksheet.
