There are graphiclayer layers in the esri:map. When you click Graphic in Graphiclayer, the Graphiclayer Mousebuttondown event is triggered and Infowindow is turned on. If you do not set e.handled=true. It also triggers the MouseClick event in the map, causing the Infowindow to open and close, and after the e.handled=true is set, the event ends after the Graphicmousebuttondown. The Mapmouseclick event is not triggered. To achieve similar Baidu open, close the information window effect.
