Let me show you the effect after implementation:
For the sake of visualization, I will post the effect I made first
List display, map display and linkage
Show information
Implementation ideas:
1. Interaction between list and map
When the mouse passes over the list, the list icon is modified and a blue marker is drawn on the map based on the value returned by the list; when the mouse is moved out, the list icon is modified to red and the map marker layer is cleared.
Key code:
title.on("mouseover",function(){
var attr = $(this).data("attr");
$("#icon"+attr.id).css("background","url('images/blue.png')");
var pt=new Point(attr.x,attr.y,{"wkid":4326});
var pms = new esri.symbol.PictureMarkerSymbol("images/blue.png",24,26)
var gImg = new Graphic(pt,pms);
gLyrHover.add(gImg);
});
title.on("mouseout",function(){
var attr = $(this).data("attr");
$("#icon"+attr.id).css("background","url('images/red.png')");
gLyrHover.clear();
});2. Interaction between map and list
When the mouse passes over the red marker on the map, the corresponding list icon is modified and the red marker picture is changed to blue; when the mouse is moved out, the corresponding list icon is modified and the marker is changed to red.
Key code:
gLyr.on("mouse-over",function(e){
map.setMapCursor("pointer");
var sms = e.graphic.symbol;
sms.url = "images/blue.png";
gLyr.redraw();
$("#icon"+e.graphic.attributes.id).css("background","url('images/blue.png')");
});
gLyr.on("mouse-out",function(e){
map.setMapCursor("default");
var sms = e.graphic.symbol;
sms.url = "images/red.png";
gLyr.redraw();
$("#icon"+e.graphic.attributes.id).css("background","url('images/red.png')");
}); 3. The ABCD text on the map is a separate layer and does not participate in interaction.
4. The data exists in JSON form.

"id":"A","name":"拉萨", "x":91.162998, "y":29.71042,
