javascript - Duplicate Marker Error in Leaflet -

-

How do you handle markers in sheet maps? My question is, when I place a marker on the map and place a different marker on the map, the first markers always come in or mix with another image.

Here is my code 

  var note = document.getElementById ('note'); Var datepick = document.getElementById ('Demo 1'); Var Timepick = document.getElementById ('Timepick'); LayerPoly.On ('click', function (e) {var marker b = new L. marker (E.latange, {icon: icon3}); marker B.DindPop ("homecad" date and date; : "+ Datepick.value +" & lt; / br & gt; Time: "+ timepick.value +" & lt; / br & gt; Address: "+ note.value +" ") addTo (map); map .addlayer (markerB); Closing 2 (Marker B)

Is there something wrong with the click event, I just want to have no other marker with the marker? Any help TYIA!

c# - WPF Expander overlay used in ItemsControl -

-
I've been searching for a while, but all the solutions I can only deal with parts of my issue. With an item control, which includes the expansion, upon expansion, the content of the extensioner should be shown as an item which is overlapping the other item in the item control and not taking them down. The following XAML-code is actually a big problem: the content of the expansion does not overlap other objects but is hidden behind them, I think it is because of ZIndex because the following in ItemsControl Items are added after expander content. I managed to set a single spreader's ZIndex 99 style triggers, but it appears to be very complicated and error-prone solution any thoughts? & lt; Window x: orbit = "wpfTest.MainWindow" xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns: x = "http://schemas.microsoft.com/winfx/2006/ Xaml "title =" main window "height =" 350 "width =" 525 "...
