jTell Me More: About the Code to Create Feed Items
In the code for the DeliveryTrakr Web application, the shipment.js file contains the logic to create the various
feed items.
Creating a Canvas Feed Item
This
code snippet from the onGetPayload function creates a feed item of type CanvasPost. As you can see, it dynamically sets all the
post values and retrieves information about the canvas app, such as
the namespace and developerName, from the signed request.
You can also pass in parameters that are appended to the URL and used
in the canvas app feed item.
1swfobject.registerObject("clippy.codeblock-0", "9");

18{
19 p.feedItemType = "CanvasPost";
20 p.auxText = "Please confirm this shipment status: " +
21 shipments[shipment].description;
22 p.namespace = sr.context.application.namespace;
23 p.developerName = sr.context.application.developerName;
24 p.thumbnailUrl = "https://cdn1.iconfinder.com/data/icons/
25 VISTA/project_managment/png/48/deliverables.png";
26 p.parameters = "{\"shipment\":\"" + shipment + "\"}";
27 p.title = shipments[shipment].description;
28 p.description = "This is a travel shipment for Shipment - " +
29 shipments[shipment].description +
30 ". Click the link to open the canvas app.";
31}Enabling the Share Button
This code snippet
is from the draw function. After
this statement is called, the Share button is enabled. This ensures
that the user can’t create a feed item until they have selected
all the required elements for the canvas app.
1swfobject.registerObject("clippy.codeblock-1", "9");

19 payload : true});Publishing the Feed Item
When the user clicks
the Share button, this code snippet publishes the feed item to the
feed. The type of feed item it creates depends on which type you select:
text, link, or canvas.
1swfobject.registerObject("clippy.codeblock-2", "9");
