Projects and Type Resolution - The Global Scope
JSDT manages type resolution and browser compatibility by allowing users to customize a projects Global Scope.
The Global Scope (as it applies to JavaScript) is the super scope which holds all the objects, types and fields accessible to all methods. Its honestly one of the horrible inefficiencies of JavaScript as just about everything gets pushed into the Global Scope.
JSDT users can customize a projects Global Scope throughout the ‘JavaScript Include Path’ page. Each library is a collection of JavaScript files that prototypes all objects within that library. (Additional information can be attached to objects with JsDoc. ). When a library is added to a project, all of the prototype code in each libraries JavaScript files is modeled and placed in the projects Global Scope. The types, fields and methods are then available for resolution and content completion in every JavaScript file within the project Matter of fact, every JavaScript file sees the Global members of every other JavaScript file within a project (unless you’ve done some careful tweaking in the Include Path page).
A piece of JS code running in a browser has access to many of the objects, fields and methods provided by the browser. The browsers ‘Window’ object is an extension of ‘Global’ which extends ‘Object’. Each browser provides different types, fields and methods to almost all of the common objects (and additionally handles these types, fields and methods differently across browsers). Hence the cross browser compatibility pain points that arise when developing JavaScript.
The JSDT forces browser compatibility by defining and extending ECMA 3 objects through the libraries. By adding and removing libraries you can nail down the types, functions and fields available in code completion and resolution. This will help ensure your project supports the objects in specific browsers.
Libraries aren’t just useful for browsers. They work well for toolkits, or common utility scripts across a site.

Doesn’t Aptana have code that shows code completion for javascript that works for each type of browser? Is JSDT working with Aptana on this?
Cool stuff though… I still think people are crazy to develop full-scale applications just using JS.

Aptana’s code completion is rather static. What really distinguishes JSDT from Aptana is JSDTs real time modeling of JavaScript.
You will notice in Aptana code completion isn’t truly context aware. You will see methods and fields on objects that aren’t relevant.
To better answer your question- JSDT and Aptana aren’t similar in architecture at all, so cooperation isn’t really possible.
Our design will allow distinguishing methods in code completion by browser and library. The library function has the ability to associate an icon with each library and show that icon during code completion for each method/field/object coming from a library.

This is good!
We are using and having a good experience with JSDT Editor.
But is there any “how to” for customizing the Global scope of our project? If we need add new libraries for JSDT Editors, how do we can do that??

Hi Victor,
Check out the “JavaScript Development Toolkit User Guide” within the Eclipse Help system. (’Help’—>’Help Contents’–>’JavaScript Development Toolkit User Guide’).
There is basic usage on the project include path and library mechanism.
Designing your own libraries is pretty easy. If you checkout the org.eclipse.wst.jsdt.support.ie or org.eclipse.wst.jsdt.support.firefox plugins from the Eclipse CVS (CVS path:/cvsroot/webtools under /wst/components/jsdt/plugins/) you will have the skeleton for a library. Really just tweak some names and replace the javascript files with your own javascrpt files and your all set.

Hi,
I want to make JSDT to recognize Dojo library is it possible?
So that I can use autocompletion, for example.
I’m sure that somebody must have tried it.
On http://wiki.eclipse.org/index.php/ATF/JSDT it says that: “Support for one or two popular toolkits such as dojo ((currently partial but non-specific))”
What does that mean?
