Skyline软件二次开发初级——5如何在WEB页面中的三维地图上使用事件函数

1.onFrame事件 - 移动摄像机：

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

        var time = 5 * 1000; // move for 5 sec.

function Init()
{
SGWorld.AttachEvent("onFrame", onFrame);

SGWorld.Navigate.JumpTo(SGWorld.Creator.CreatePosition(-100.0, 40.0, 13000000, 3, 0, -85));
            setTimeout(function () { SGWorld.DetachEvent("onFrame", onFrame); }, time);
        }

        function onFrame()
        {

var pos = SGWorld.Navigate.GetPosition();

            pos.X += 0.5;
            pos.Y -= 0.2;

SGWorld.Navigate.SetPosition(pos);

        }

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

2.onFrame事件 - 移动对象：

<html>
    <head>
        <title>onFrame - Move objects</title>
        <object id="SGWorld" classid="CLSID:3a4f91b1-65a8-11d5-85c1-0001023952c1" style="visibility:hidden;height:0 "></object>
        <script src="abspath.js" type="text/javascript"></script>
        <script type="text/javascript">

var model = null;
        var time;

        function Init()
        {
            time = new Date();
            SGWorld.AttachEvent("onFrame", onFrame);

            var pos = SGWorld.Creator.CreatePosition(-122.38050, // x
                                                  37.62331,  // y
                                                  40.0,      // height
                                                  3,         // height type
                                                  297.0,     // yaw
                                                  15.0,      // pitch
                                                  0,         // roll
                                                  0          // dist
                                                  );

            model = SGWorld.Creator.CreateModel(pos, toAbspath("data/747.xpc"), 0.2);

model.Attachment.AutoDetach = false;

            SGWorld.Navigate.FlyTo(model);
        }

        function onFrame(elapsedTime)
        {
            // move object with speed of 400km/h
            var distToMove = (400 * 1000 / 3600) * (new Date().getTime() - time.getTime()) / 1000;

model.Position = model.Position.Move(distToMove, model.Position.Yaw + 0.1, model.Position.Pitch);
            time = new Date();
        }

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

3.onLButtonDown事件：

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

        var globe = null;
        var pos   = null;
        var popup, popup2;

        function Init()
        {

SGWorld.AttachEvent("onLButtonDown", onLButtonDown);
            SGWorld.AttachEvent("onRButtonDown", onRButtonDown);
            popup2 = SGWorld.Creator.CreatePopupMessage()
            popup2.InnerText = "Left click on the terrain to get the coordinates at cursor position. Right click to finish.";
            SGWorld.Window.ShowPopup(popup2);
        }

        function onLButtonDown(flags, x,y)
        {
            var ret = SGWorld.Window.PixelToWorld(x, y);

            popup = SGWorld.Creator.CreatePopupMessage("onLButtonDown event", "", x, y);

            popup.InnerText = (ret == null) ? "Screen coordinate hit the sky" : "Screen coordinates ("+x+","+y+"):\nTerrain coordinate:\nX: " + ret.Position.X + "\nY: " + ret.Position.Y;

SGWorld.Window.ShowPopup(popup);

return true; // event was processed by the client. return false to allow additional processing of the event.
        }

        function onRButtonDown(flags, x,y)
        {

SGWorld.DetachEvent("onLButtonDown", onLButtonDown);
SGWorld.DetachEvent("onRButtonDown", onRButtonDown);

if(popup)
                SGWorld.Window.RemovePopup(popup);
            if(popup2)
                SGWorld.Window.RemovePopup(popup2);

            return true; // event was processed by the client. return false to allow additional processing of the event.
        }

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

4.屏蔽右键弹出菜单：

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

        function Init()
        {
            SGWorld.AttachEvent("onRButtonDown", onRButtonDown);
            SGWorld.AttachEvent("onRButtonDblClk", onRButtonDblClk);

SGWorld.Window.ShowMessageBarText("This sample shows how to disable the default right context menu. Double right-click to re-enable", 3);
        }

        function onRButtonDown(flags, x,y)
        {

return true; // Tell TE that the OnRButtonDown event was processed by the client
        }

        function onRButtonDblClk(flags, x,y)
        {
            SGWorld.DetachEvent("onRButtonDown", onRButtonDown);
            SGWorld.DetachEvent("onRButtonDblClk", onRButtonDblClk);
            SGWorld.Window.HideMessageBarText();

alert("Right click is now enabled");

            return false;
        }

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

5.onTerraExplorerMessage事件：

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

        function Init()
        {
            SGWorld.AttachEvent("onTerraExplorerMessage", onTerraExplorerMessage);

var label = SGWorld.Creator.CreateTextLabel(SGWorld.Creator.CreatePosition(-71.00425, 42.36081, 100),
"Click here to get the name of the airport",SGWorld.Creator.CreateLabelStyle());

var msg = SGWorld.Creator.CreateMessage(0, "Logan International",0);
label.Message.MessageID = msg.ID;

SGWorld.Navigate.JumpTo(label);
        }

        function onTerraExplorerMessage(messageId, senderNodeId)
        {
            var message = SGWorld.Creator.GetObject(messageId);
            var senderNode = SGWorld.Creator.GetObject(senderNodeId);
            senderNode.Text = message.Text;
        }

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