[RESOLVED] Javascript

Can somebody point out if I am doing something really stupid here?

Here's my script:

Code:

<head runat="server"> <title></title> <script type="text/javascript" src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2"></script> <script type="text/javascript"> function MapIt { var map = null; var CurrentPos = null; var pinPoint = null; var pinPixel = null; var lat = document.getElementById("<%=txtMapLat.ClientID%>").value; var lon = document.getElementById("<%=txtMapLon.ClientID%>").value; var latlist = lat.split(","); var longlist = lon.split(","); CurrentPos = new VELatLong(latlist[0], longlist[0]); map.LoadMap(CurrentPos, 15, VEMapStyle.Road, false, VEMapMode.Mode2D, true, 1); for(var i=0; i < field1.length;i++){ CurrentPos = new VELatLong(latlist[i], longlist[i]); pinPoint = map.GetCenter(); pinPixel = map.LatLongToPixel(pinPoint); map.AddPushpin(pinPoint); } }; </script> </head>

I link it to an asp: button:

Code:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Button1.Attributes.Add("onclick", "MapIt();") End Sub

When I run it I get an:

Microsoft JScript runtime error: Object expected

on MapIt(); like it has no idea what the function is.

Re: Javascript

Hey,

Which version of Visual Studio are you using? Visual Studio 2008 allows you to set BreakPoints in your JavaScript:

Lol yeah I just figured out this morning on accident that I could do that. That helps a lot.

Re: [RESOLVED] Javascript

If you're using VE 6.2, some of your code is deprecated now. Have a look here for changes between versions:

http://msdn.microsoft.com/en-us/library/cc161073.aspx

Pushpins are now added like so:

Code:

var pin = new VEShape(VEShapeType.Pushpin, latlong); pin.SetCustomIcon(icon_url); pin.SetTitle(title); pin.SetDescription(details); map.AddShape(pin);

The reason this is relevant is because they control the JS, they can actually remove the method support completely at any point. I'm sticking with V6 though.

Yeah I already made the change to using shapes, but thanks.
