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.

var data = [ 
 { 
 "id":"A","name":"拉萨", "x":91.162998, "y":29.71042, 
 "desc":"拉萨是中国西藏自治区的首府，西藏的政治、经济、文化和宗教中心，也是藏传佛教圣地。" 
 }, 
 { 
 "id":"B", "name":"西宁","x":101.797303,"y":36.593642, 
 "desc":"西宁是青海省的省会，古称西平郡、青唐城，取”西陲安宁“之意，是整个青藏高原最大的城市。" 
 }, 
 { 
 "id":"C","name":"兰州","x":103.584297,"y":36.119086, 
 "desc":"兰州，甘肃省省会，西北地区重要的工业基地和综合交通枢纽，西部地区重要的中心城市之一，丝绸之路经济带的重要节点城市。" 
 }, 
 { 
 "id":"D","name":"成都","x":104.035508,"y":30.714179, 
 "desc":"成都，简称蓉，四川省省会，1993年被国务院确定为西南地区的科技、商贸、金融中心和交通、通讯枢纽。"
