How To Pass Data From Code Behind To Javascript?

Hi I am having trouble to pass a value from a code behind (onLoad) to javascript. I am able to get the value for the address of the draggable marker(if INITIAL LAT and LONG value d

Solution 1:

Easiest way is to use Literal server control, and pass the value. It is kind of weird, but it works.

var markers = [{
   ...
   "lat": <asp:Literal runat="server" ID="LatLiteral" />,
   "lng": <asp:Literal runat="server" ID="LngLiteral" />
}];

Protected Sub Page_Load(sender AsObject, e As EventArgs) Handles Me.Load
   LatLiteral.Text = "43.7328831"
   LngLiteral.Text = "-79.6784712"
End Sub

Visual Studio

Notice that Visual Studio will complain for syntax error. You can ignore it.
