Find Rangy marker ID

Question

I'm attempting to find the markerId value of a saved rangy selection.

I've tried the following:

marker = savedSel.rangeInfos;
console.log(marker.markerId);

But it returns "undefined". Outputting the marker variable directly returns an object that clearly has "markerId" as an item. I just seem to be having trouble getting to that third dimension in the multidimensional object.

How could this be done?

rangeInfos is an array because a selection can have multiple ranges in Firefox. If you've saved a collapsed selection (i.e. there is no selection, just a caret) then you can get the marker ID from the first and only member of rangeInfos:

var savedSel = rangy.saveSelection();
console.log(savedSel.rangeInfos[0].markerId);
