(5) appears to have been done.
The issue with (4) is that when the sidebar entries are created, they
are simply created. There is no reference included in order to be able
to refer to a particular entry later on. There is a removeFeatureEntry
() function, but it's empty.
So: you need to create a reference within the sidebar entry so you can
refer to it again. I suggest the following, but none of it is tested,
so make a copy of your code first!
Alter line 169 of gmarkers.js to read
var cells = addFeatureEntry("Placemark " + (++markerCounter_),
color, markerCounter_);
in order that markerCounter is passed in its own right to the sidebar
function. This is the most problematic line, because we need the two
values of markerCounter to be the same and the first one increments
it. You may need to split it up like
++markerCounter_;
var cells = addFeatureEntry("Placemark " + markerCounter_, color,
markerCounter_);
Alter line 112 so it makes use of it:
function addFeatureEntry(name, color, number) {
After line 113, add a new line to use that parameter:
currentRow_.setAttribute("id","PM" + number); // ids need to start
with a letter
// This adds an id attribute to the placemark's row in the table
Then write the content of the removeFeatureEntry() function:
document.getElementById("featuretbody").removeChild("PM"+number);
// This removes the row from the tbody element
