Baidu Map to add the right button menu (to determine whether it is marker) _javascript tips

No more nonsense to say, directly to everyone paste code.

Js:

var s;//longitude
var w;//latitude
map.addeventlistener ("RightClick", function (e) {
if (e.overlay) {// Determine if the right mouse click is marker
}else{
s = e.point.lng;//longitude
w = e.point.lat;//dimension
rightclick ();//Right-click Map appears with right-click menu Event
}
});
Right-click Map appears right-click menu Event
function RightClick () {
//alert (' You clicked on Map ');
var createmarker = function (map) {//Right-click Update Station name
if (confirm) ("Do you want to create a new site?") ")) {
if (true) {
$ (). Allsetmassage "). Show (),}} 
;
var markermenu=new bmap.contextmenu ();
Markermenu.additem New Bmap.menuitem (' New site ', Createmarker.bind (map));
Map.addcontextmenu (Markermenu);//Add right-click menu to tag

Effect:

Right-click Map (non marker)

Right-click Marker:

PS: Baidu map to multiple marker add right menu (delete, update)

Js:

$.getjson ("./getstationplaceservlet", function (JSON) {for (Var i=;i<json.length;i++) {var obj = eval (JSON);//Get Latitude and longitude Fstationlon = parsefloat (Obj[i].
Stationlon); Fstationlat = parsefloat (Obj[i]. 
Stationlat);
var pt = new Bmap.point (Fstationlon,fstationlat);
var Myicon = new Bmap.icon ("Photo/station.png", New Bmap.size (,), {anchor:new bmap.size (,)}); var marker = new Bmap.marker (Pt,{icon:myicon}); Create callout Map.addoverlay (marker); Add a callout to the map var strres = parsefloat (obj[i).
Stationid); Addclickhandler (Strres,marker);//Left click Marker event Rightclickhandler (strres,marker)//Right-click Marker appears right-click menu Event RightClick ()
//Right key map appears right-click menu event}});
Right-click Marker appears right-click menu event Function Rightclickhandler (stationid,marker) {var removemarker = function (e,ee,marker) {//right mouse delete site
var json={"Stationid": Stationid,}; if (Confirm to delete site "+stationid+"?) {if (true) {$.getjson ("./deletestationservlet", {json:JSON.stringify (JSON)},function (JSON) {if (json.result== true) {alert ("delete site" +stationid+ success!)
"); Map.removeoverlay (marker); Delete the tags in the map} 
});
}
} 
}; var updatemarker = function (marker) {//Right-click Update Station name if (confirm) to modify site "+stationid+" station name? ")) {if (true) {$ ().
Allupdatemassage "). Show ();
$ ("#stationId"). Val (Stationid);
}
} 
};
var markermenu=new bmap.contextmenu ();
Markermenu.additem (New Bmap.menuitem (' Delete site ', Removemarker.bind (marker));
Markermenu.additem (New Bmap.menuitem (' Modify station name ', Updatemarker.bind (marker));
Marker.addcontextmenu (Markermenu);//Add right-click menu}//left mouse button Click Marker event function Addclickhandler (stationid,marker) { Marker.addeventlistener ("click", Function (e) {var p = marker.getposition ();//Get marker location var staid={"Stationid":
Stationid,}; $.getjson ("./getstationinfoservlet", {json:JSON.stringify (staid)},function (JSON) {for (Var i=;i<json.length;i++ {var obj = eval (JSON); stationname = obj[i].stationname var content = "Site number: +stationid+" <br/> "+" Site name: "+stationn
Ame
OpenInfo (content,e);
}
});
}); //Left click Marker Popup event function OpenInfo (content,e) {var p = e.target; var point = new Bmap.point (P.getposition (). LNG, P.get PositIon (). lat); var Infowindow = new Bmap.infowindow (content,opts); Create an Information Window object Map.openinfowindow (infowindow,point); Open the Info Window}//Modify the Site name Function update () {var stationid=$ ("#stationId"). Val ()//number Var stationname=$ (". 
Allupdatemassage_name "). Val ();//name var json={" Stationid ": Stationid," StationName ": StationName}; $.getjson ("./updatestationservlet", {json:JSON.stringify (JSON)},function (JSON) {if (json.result==true) {alert ("site" +stationid+ "Station name modification success!"
"); $(".
Allupdatemassage "). Hide (); } else{alert ("Failed!") ");
}
});
}

Effect Chart:

This point information has been deleted on the map and in the database:

When I implemented this, I found that someone could only add a right-click menu to a marker. I don't have this problem. The principle seems to be about closure of what, I am also novice is not very clear, hope to understand people do not hesitate to advise.
