Description

This extension provides support for jQuery.

In what situation should you install this extension?

If your Web application contains jQuery source code and you want to view these object types and their links with other objects, then you should install this extension:

• Creates jQuery events and access points to services:
  
  • jQuery events: they represent a query in DOM tree
  • jQuery access points to web services: CAST_JQuery_GetResourceService, CAST_JQuery_PutResourceService, CAST_JQuery_PostResourceService
• Creates links (direct or indirect) from jQuery events to jQuery access points to services (these links are created by the jQuery extension and the HTML5/JavaScript extension).
• Links from the jQuery access points to services to different servers written in other languages are then created by the WBSlinker extension (an internal extension).
• The following declarations will create a jQuery event:

$('#advancedLoginOptionsLink').bind('click', dm.login.toggle_advanced);
$('#advancedLoginOptionsLink').click(dm.login.toggle_advanced);
$('#advancedLoginOptionsLink').on('click', this.destroy.bind(this));....

• The following declaration will create objects "call to web service" (these calls are resolved to web service operations on the server side for the following supported frameworks: Node.js, JAX-RS, Spring MVC:

/* GET REQUEST USING AJAX OR GET ANNOTATIONS */
$.ajax({
  url: url,
  data: data,
  success: success,
  dataType: dataType
});
 
$.get( "ajax/test.html", function( data ) {
  $( ".result" ).html( data );
  alert( "Load was performed." );
});

/* POST REQUEST USING AJAX OR POST ANNOTATIONS */
$.ajax({
  type: "POST",
  url: url,
  data: data,
  success: success,
  dataType: dataType
});
 
$.post( "ajax/test.html", function( data ) {
  $( ".result" ).html( data );
});

Transaction configuration

Default entry point is the HTML file content.

Supported jQuery versions

• 1.0 - 3.0

Function Point, Quality and Sizing support

This extension provides the following support:

• Function Points (transactions): a green tick indicates that OMG Function Point counting and Transaction Risk Index are supported
• Quality and Sizing: a green tick indicates that CAST can measure size and that a minimum set of Quality Rules exist

Function Points (transactions)	Quality and Sizing	Security

Comparison with existing support for JavaScript in CAST AIP

CAST AIP has provided support for analyzing JavaScript via its JEE and .NET analyzers (provided out of box in CAST AIP) for some time now. The HTML5/JavaScript extension (on which the jQuery extension depends) also provides support for JavaScript but with a focus on web applications. CAST highly recommends that you use this extension if your Application contains JavaScript and more specifically if you want to analyze a web application, however you should take note of the following:

• You should ensure that you configure the extension to NOT analyze the back end web client part of a .NET or JEE application.
• You should ensure that you configure the extension to ONLY analyze the front end web application built with the HTML5/JavaScript that communicates with the back end web client part of a .NET or JEE application.
• If the back end web client part of a .NET or JEE application is analyzed with the jQuery extension and with the native .NET/JEE analyzers, then your results will reflect this - there will be duplicate objects and links (i.e. from the analyzer and from the extension) therefore impacting results and creating erroneous Function Point data.

CAST AIP compatibility

This extension is compatible with:

CAST AIP release	Supported
8.3.x
8.2.x
8.1.x
8.0.x
7.3.4 and all higher 7.3.x releases

Supported DBMS servers

This extension is compatible with the following DBMS servers:

CAST AIP release	CSS2	Oracle	Microsoft
All supported releases

Prerequisites

An installation of any compatible release of CAST AIP (see table above)

Dependencies with other extensions

Some CAST extensions require the presence of other CAST extensions in order to function correctly. The jQuery extension requires that the following other CAST extensions are also installed:

• HTML5/JavaScript
• Web services linker service (internal technical extension)
