JavaScript

// Using a REST demo API "Job management"
// - Use the HTTP methods PUT, POST, DELETE, GET for specifying the operation
// - item id as part of URL makes URL a representation of a server side item
// - "Accept:application/json" header field: requests JSON for data transport
// - Additionally shows how to use cross domain requests

// The "global players" : 

var jobs, server,            // Model parts (client and stub for server)
    controller,              // Controller
    events,                  // A tiny event registration service
    table, inputArea, msg    // View parts
    ;
