Should be useful from time to time and I really shoud stop using those comfortable for-in-loops…

Addition:

Also is the inverted version of the reversed while loop faster than the ordinary cached for loop.

In short: for (var i=0, len=arr.length; i<len; i++) { } == 5 ms

var i = arr.length-1, j=0; while(--i) {++j;}; == 7 ms

Both tested on my 1.6 Ghz Notebook in battery mode with a simple array with 100,000 entries.

1. There should be no need of a MySQL database, because it should be simply uploaded onto the server and should work out of the box.
2. It should be free of charge.
3. To create a new gallery, it must be possible to upload all images via a ftp application. A form with manually selection of each image a time is not practicable due to the number of images.
4. There should be threeimage sizes per image available. One is a thumbnail to show in galleries, one is a medium sized image to use at image to view. It turned out that the third image really is a tough one, there must be an original sized version of this image for downloading.

So, I looked around for gallery scripts. (more…)

On InteRiders there is also a version in prototype available. Mental notice: If I have time, I should implement a jquery version or probably a version without framework.

var obj1 = function() {};
obj1.prototype = {
 foo: "foo-obj"
};

var obj2 = obj1;
obj2.prototype.foo2 = "obj";
obj2.prototype.setFoo = function(val) {this.foo = val;};

But that looks nothing like object oriented code I used to write in other languages. Besides, writing all of this .prototype seems more complicated as it should be. So I looked further. With prototype you can write:

var Animal = Class.create({
 initialize: function(name, sound) {
 	this.name  = name;
 	this.sound = sound;
 },	speak: function() {
 	alert(name + " says: " + sound + "!");
 }
});
// subclassing Animal
var Snake = Class.create(Animal, {
 initialize: function($super, name) {
 	$super(name, 'hissssssssss');
 }
});

From Prototype documentation

Pretty good so far, but there are still some issues. The greatest issue is, you need prototype to create such classes. For some projects prototype is useful, for small projects it is simply to much. Besides you can’t create classes which inherit from multiple classes, and this $super in that constructor, must I really write that? I mean, within the parameterlist of a function should only be variables, that you expect when calling var snake1 = new Snake("billy the snake");

So I thought about it and a little bit inspired by all I saw I decided what I wanted to write. Code like that:

var ParentClass = new Class.create({
initialize: function(fooval) {this.foo = fooval;}
,    foo: ""
,    setFoo: function(val) { this.foo = val; }
});

var SubClass = new Class.create({
initialize: function() {this.super("barent");}
,    foo2: "barcelona"
}, ParentClass);

So I developed 23 lines that make this possible. Here it is:

var Class = {
	create: function() {
		var t = function() {if(this.initialize) this.initialize.apply(this, arguments);};
		t.prototype.super = function() {
			if(typeof this._super != "undefined")
				this._super.initialize.apply(this, arguments);
		};
		t.extend = function() {
			for(var i = 0; i < arguments.length; ++i) {
				if(typeof arguments[i] == "function")
					arguments[i] = new arguments[i]();
				for (var property in arguments[i]) {
					if(!t.prototype[property])
						t.prototype[property] = arguments[i][property];
				}
				if(typeof t._super == "undefined")
					t.prototype._super = arguments[i];
			}
		};
		t.extend.apply(t, arguments);
		return t;
	}
};

For all, who want some examples what these 23 lines can do, I created a page for this Class-object. If you have feedback and/or more ideas I would like to hear about it.

So back to my jaz formValidator… (more…)

Especially Textpattern has some nice ideas in their template engine which I picked up and extended in this template engine. (more…)

So if you have old bookmarks to some net-lounge.de sites, you can change them to jaz-lounge.com.

Indeed, there are possibilities to use PHP as one and wikipedia.org says it is one. And of course it runs alone faster then every template engine you can build upon it. So where is the big deal?

This article tries to discuss what a template engine really is and what it is not. (more…)

I hope this feature pleases all who ever wanted to take notes while reading a post or are annoyed having read it to the end and then forgot what they wanted to write. It always happens to me. Maybe I’m not the only one. But if you like it more the old way, you can put that commentform to its old place. Just uncheck that checkbox labeled “Dock out commentform” to put it back where it belongs.

This all is achieved with unobtrusive javascript. That means if your user have no javascript active they don’t see any changes. For setting it up you have to change some values in the comment.js or it will float at left:65%. If it is ok for you, than simply activate it.

Here is the downloadable zip-archive of my jazCommentform Floater.

This plugin works well on Firefox and Internet Explorer 6. On Safari I haven’t tested it yet but maybe in a few days.

If you have found a bug, please write a comment so I can fix it. You also can leave me a comment if you like it, have some ideas to enhance it or you think something should be better.
