Dojo Goodness, Part 9 (gfx foo with fx)

Wed, 2008-06-11 14:21 β€” Spider84

Matthew Russel post the next article from his series about Dojo JavaScript library. Here's small excerpt from this article with one example:

«In preparation for my OSCON talk, I’ve been unearthing some of the fx enhancements that were added to Dojo’s gfx module back when version 1.1 landed. Some of these enhancements are pretty neat, and I thought they might make for a good excuse to get you started with a part of the toolkit you may not have ventured into quite yet.

Let’s get right to it with a document that demonstrates the fundamentals of how to create a gfx drawing context and place a shape somewhere on it:

<html>

<head>

<title>Fun with gfx!</title>

<script

type="text/javascript"

src="http://o.aolcdn.com/dojo/1.1/dojo/dojo.xd.js"

djConfig="isDebug:true">

</script>

<!--

Workaround necessary for loading gfx over the CDN until 1.2

lands. See http://trac.dojotoolkit.org/ticket/4462

-->

<script

type="text/javascript"

src="http://o.aolcdn.com/dojo/1.1/dojox/gfx.js">

</script>

<script type="text/javascript">

dojo.require("dojox.gfx"); //maintain good form

dojo.addOnLoad(function() {

//create a 200x200 drawing surface

var g = dojox.gfx.createSurface(dojo.byId("g"), 200, 200);

//draw a circle on it at (100,100) with a radius of 10

var circle = g.createCircle({cx : 100, cy : 100, r : 10})

.setFill("blue");

});

</script>

</head>

<body>

<div id="g"></div>

</body>

</html>»

Dojo Goodness, Part 6 (A Million Records in the Grid)

Thu, 2008-04-24 13:02 β€” Spider84

Matthew Russel published the next article from his series about Dojo Javascript library. In this article he tells about handling very large datasets and shoind the data in grids. He writes the following:

«It’s a given that you can use the grid to display relatively small data sets effectively in the browser and get the niceties of sorting, column resizing, etc. that come along with it. That’s cool and all, but there’s a practical limit to the number of records you can deal with at any given time, which eventually leads to the concept of paginating results.

Well, go ahead and forget about pagination; those days are finally over. Dojo’s grid works by lazy loading data as the grid scrolls. For a relatively small data set consisting of hundreds of records, lazy loading amounts to building out the DOM for a pre-loaded data set when you scroll. For example, if you had 100 records but could only view 20 of them at a time, you wouldn’t want to build the nodes for any of the records in 21 through 100 until you scrolled to that particular section. Sorting by a column and related tasks work in memory as expected for small data sets since you can effectively get things done in JavaScript. »

Simple JavaScript Inheritance

Thu, 2008-03-20 12:29 β€” Spider84

John Resig writes about one of main object oriented programming concepts in JavaScript Language — Inheritance. He writes:

«I've been doing a lot of work, lately, with JavaScript inheritance - namely for my work-in-progress JavaScript book - and in doing so have examined a number of different JavaScript classical-inheritance-simulating techniques. Out of all the ones that I've looked at I think my favorites were the implementations employed by base2 and Prototype.
