                 "lng": '<%# Eval("Longitude") %>',
                 "description": '<%# Eval("Description") %>'
             }
    </ItemTemplate>
    <SeparatorTemplate>
        ,

It's an old post but this reference helped me figure out the exact same issue. asp repeater syntax error

The idea is to use code-behind to generate your repeater list.

  var markers = [
// start of generated objects from code-behind

        <%=getMarkerObjects() %>

// end of generated objects from code-behind
    ];

Now in your code-behind

    Protected Function getMarkerObjects() As String
    Const indent As String = "    "
    Dim dt = New DataTable
    dt.Columns.AddRange({New DataColumn("Name", GetType(String)), New DataColumn("Latitude", GetType(Double)), New DataColumn("Longitude", GetType(Double)), New DataColumn("Description", GetType(String))})
    dt.Rows.Add({"p1", 32.2217, -110.9264, "p1"})
    dt.Rows.Add({"p2", 31.9556, -110.3067, "p2"})
    Dim ret As String = String.Empty
    For Each r In dt.Rows
        ret &= IIf(ret.Equals(String.Empty), "", indent & "," & vbCrLf) &
            indent & "{" & vbCrLf &
                indent & indent & """title"": '" & r("Name") & "'," & vbCrLf &
                indent & indent & """lat"": '" & r("Latitude") & "'," & vbCrLf &
                indent & indent & """lng"": '" & r("Longitude") & "'," & vbCrLf &
                indent & indent & """description"": '" & r("Description") & "'" & vbCrLf &
            indent & "}" & vbCrLf
    Next
    Return ret
End Function
