5five Mootools + js TEST

Fx.FontPlus

Fx.FontPlusはオサレだが、ページ移動すると元に戻る。普通にstyleSwitcherで十分に思われるし、ブラウザのテキストリサイズでもいいような気がする。しかし、ちょっとしたときには便利かも。ま、それほど必要とは思いません。

Fx.FontPlus = new Class({
	initialize: function(elements, sid, gid, gmid, growsize, growmoresize){
		this.growsize = (growsize) ? growsize : 2;
		this.growmoresize = (growmoresize) ? growmoresize : 4;
		
		this.elements = [];
 		elements.each(function(el){
			this.elements.push([el,el.getStyle('font-size').toInt()]);									   
		},this);
		
		$(gmid).onclick = function(){this.growmore()}.bind(this);
		$(gid).onclick = function(){this.grow()}.bind(this);
		$(sid).onclick = function(){this.shrink()}.bind(this);		
	},
	
	growmore: function(){
		this.elements.each(function(el){
			var currentfsize = el[0].getStyle('font-size').toInt();
			if(currentfsize == el[1])
				el[0].effect('font-size',{duration:300,unit:'px'}).custom(el[1],el[1]+this.growmoresize);
			else if(currentfsize == el[1]+this.growsize)
				el[0].effect('font-size',{duration:300,unit:'px'}).custom(el[1]+this.growsize,el[1]+this.growmoresize);			
		},this);							
	},
	
	grow: function(){		
		this.elements.each(function(el){
			var currentfsize = el[0].getStyle('font-size').toInt();
			if(currentfsize == el[1])
				el[0].effect('font-size',{duration:300,unit:'px'}).custom(el[1],el[1]+this.growsize);
			else if(currentfsize == el[1]+this.growmoresize)
				el[0].effect('font-size',{duration:300,unit:'px'}).custom(el[1]+this.growmoresize,el[1]+this.growsize);	
		},this);							
	},
	
	shrink: function(){

slimBox

slimBoxはlightBoxと全く同じ。prototype.jsなのかmootools.jsなのかの違いなだけ。何にしても最も有用なjsだと思います。ただ、lightBoxの方が軽いと思います。動作が。

var Lightbox = {

	init: function(options) {
		this.options = Object.extend({
			resizeDuration: 400,	// Duration of height and width resizing (ms)
			initialWidth: 250,		// Initial width of the box (px)

			animateCaption: true	// Enable/Disable caption animation
		}, options || {});
		
		this.anchors = [];
		$A(document.getElementsByTagName('a')).each(function(el){
			if(el.rel && el.href && el.rel.test('^lightbox', 'i')) {
				el.onclick = this.click.pass(el, this);

accordion もしくは moo.fx

accordionは有効な手段ですね。サイトの作りが根底から変わるjsです。シンプルなページ作りには欠かせないのかもしれません。you are the here がついてからさらに魅力的になりました。

tooltip

これは初期値がaタグ全てのtitle属性をかっさらっていきます。そのまんま使うとlightBox系のdiscription用のtitle属性が無効になるので、aタグにclassを振って、tooltipを適応するものを個別に指定して使うのが良いと思われます。何でもかんでもtooltipで表示されると鬱陶しいので。

var as = [];
$S('a.tip').each(function(a){
	if (a.getAttribute('title')) as.push(a);
});
new Tips(as, {maxOpacity: 0.9, maxTitleChars: 25});

var as = [];
$S('a.tip').each(function(a){
	if (a.getAttribute('title')) as.push(a);
});
new Tips(as, {maxOpacity: 0.9, maxTitleChars: 25});

var as = [];
$S('a.tip').each(function(a){
	if (a.getAttribute('title')) as.push(a);
});
new Tips(as, {maxOpacity: 0.9, maxTitleChars: 25});

var as = [];
$S('a.tip').each(function(a){
	if (a.getAttribute('title')) as.push(a);
});
new Tips(as, {maxOpacity: 0.9, maxTitleChars: 25});

jdSlideshow

このスライドショーをいかにして有効に使うかは、ユーザーのセンスが問われる。
