Client Side API Programming

A JavaScript object called "WL" is created by the Worklight framework. This can then be used as

the root or name-space for all other functions.

WL.Client

The JavaScript object called "WL" contain a child object called "Client" which acts as a container

for a set of methods related to client side functions. The following act as a guide and notes on some

of the functions available.

The common "options" object

Many of the functions documented here accept an "options" object. This object is common

amongst many of the asynchronous calls. This object contains the following properties:

• onSuccess – A callback function that receives a "response" object. The response object

will contain (amongst other items):

◦ invocationContext

◦ status

• onFailure – A callback function that is invoked if an error/failure is detected. The

function is passed a response object which will contain:

◦ invocationContext

◦ errorCode

◦ errorMsg

◦ status

• invocationContext – An object which will be passed through to the response objects so that

they may have context/correlation between a call and a response. This is necessary since

many of the responses will be returned asynchronously.

WL.Client.addGlobalHeader(headerName, headerValue)

When called this method adds an HTTP header to the network connections made in all subsequent

requests to the Worklight Server.

• headerName – The name of the HTTP header property to add.

• headerValue – The value of the HTTP header property to add.
