OS:Passing data to apps and navigation

Passing data to your application through requestNavigateTo() †

If you are using the opensocial.requestNavigateTo() calls, you may supply an optional parameter containing data to be passed to the new page.

The following code passes two variables: foo and bar to the canvas surface of the current application:

  function gotoCanvas(params) {
   var canvas_surface = new opensocial.Surface("canvas");
   opensocial.requestNavigateTo(canvas_surface, params);
 };

 var my_params = {
   foo : 12345,
   bar : "Bar value"
 };

 gotoCanvas(my_params);

In the canvas view, check for these values with the following code:

  var prefs = opensocial.getEnvironment().getParams();
 var foo = prefs["foo"];
 /* foo contains 12345 */

 var bar = prefs["bar"];
 /* bar contains "Bar value" */

You should see that after the navigation has taken place, your URL will look similar to:

http://sandbox.orkut.com/Application.aspx?appId=xxxxxx&uid=xxxxxx&appParams=foo%3D12345%26bar%3DBar%20value

This follows the same format as discussed in Passing data to your application through the querystring
