Skyline软件二次开发初级——9如何在WEB页面中的三维地图上进行交互

1.屏幕坐标转换为空间坐标：

<html>
    <head>
        <title>Coordinates 1</title>
        <object id="SGWorld" classid="CLSID:3a4f91b1-65a8-11d5-85c1-0001023952c1" style="visibility:hidden;height:0 "></object>
        <script type="text/javascript">

        var popup = null;


        function Init()
        {

            SGWorld.AttachEvent("onLButtonUp", onLButtonUp);
            SGWorld.Window.ShowMessageBarText("Click on terrain to get information", 2);
            popup = SGWorld.Creator.CreatePopupMessage("3D Window sample");
        }

        function onLButtonUp(flags, x,y)
        {

            var ret = SGWorld.Window.PixelToWorld(x, y);

            if ((ret.Type & 0x00000020) == 0)
            {
                popup.InnerHTML = "x: " + ret.Position.X.toFixed(5) + "<br>";
                popup.InnerHTML += "y: " + ret.Position.Y.toFixed(5) + "<br>";

                if (ret.ObjectID)
                {
                    var object = SGWorld.Creator.GetObject(ret.ObjectID);
                    popup.InnerHTML += "<br><u>Object detected:</u><br>";
                    if(object.TreeItem)
                        popup.InnerHTML += "Name: \"" + object.TreeItem.Name + "\"<br>";
                    else
                        popup.InnerHTML += "Object is not in project tree<br>";
                    popup.InnerHTML += "Type: " + object.ObjectType + "<br>";
                }
            }
            else
            {
                popup.InnerHTML = "Hit the sky";
            }

            popup.Width = 250;
            popup.Align = "TopLeft";
            SGWorld.Window.ShowPopup(popup);

            return false; // let the system continue processing the event
        }


        function Uninit()
        {
            if(SGWorld.Project.Name == "")
                return;
            SGWorld.Window.HideMessageBarText();
            if(popup)
                SGWorld.Window.RemovePopup(popup);
        }

        </script>
    </head>
    <body onload="Init();" onunload="Uninit()">
    </body>
