jqueryぽく書けたら便利そうなので書き直してみた

JavaScriptの勉強がてらjquery.jsを読み解くを読んだ。
まだ、最初の方でつまづいていますが。JavaScriptってこんな書き方ができたんだという発見があります。
でjqueryっぽく自前のスクリプトを書き直してみた。

書き直したスクリプト

//
var hvg = function(sel){
    return new hvg.prototype.init(sel);
}
hvg.fn = hvg.prototype  = {
	'init'  : 	function (sel){
									if(sel.length == 0) return false;
									this.group = [];
									this.p_x = 0;
									this.p_y = 0;
									var slen = sel.length;
									var hl = new Number();
									var grouping = new Array();
									var order = function(a,b){return a['left'] - b ['left']}
									var gorder = function(a,b){return b['n'] - a ['n']}
									//order = function(a,b){return b['top'] - a ['top']}
									for(var i = 0; i <slen ; i++)hl += Math.abs(sel[i].visibleBounds[1]-sel[i].visibleBounds[3]);
									var hl = hl/slen;

									var test = function (){	
										for(var j = 0; j < grouping.length ; j ++){
												var d = Math.abs(ic - grouping[j].n);
												if(d < hl ){
													grouping[j].item.push(sel[i]);
													return;
												}
										}
										grouping.push({n :ic , item : [sel[i]]});
										return ;
									}

									for(var i = 0; i < slen ; i++){
										var ic = (sel[i].visibleBounds[3]+sel[i].visibleBounds[1])/2;
										test();
									}

									for(var i = 0; i < grouping.length; i++){
										temp = new Array();
										for(var j = 0; j < grouping[i].item.length;j++){temp.push(grouping[i].item[j])}
										grouping[i].item = temp.sort (order);
									}
									this.group = grouping.sort(gorder);
									return this;
				},
//get Item to X,Y position
	'getItem' : 	function(y,x){
										try{
										return this.group[y].item[x];
										}catch(e){
										return false;	
										}
				},
	'next' : 	function(){
							if(this.group[this.p_y].item.length > this.p_x){
										var get = this.getItem(this.p_y,this.p_x);
										this.p_x++;
							}else{
										this.p_y++;
										this.p_x = 0;
										if(this.group.length > this.p_y){
											var get = this.getItem(this.p_y,this.p_x);
											this.p_x++;
										}else{
											return false;
										}
							}
							return get;
				},
	'each' : function(fnc,args){
						var i;
						if(typeof fnc == 'function')while(i = this.next())fnc.call(i,i,args);
						this.p_x = 0;
						this.p_y = 0;
						return this;
			   }
}
hvg.prototype.init.prototype = hvg.prototype;
//

こんな感じで記述可能に

/*
#includepath 'path of lib'
*/
#include 'hvg.js';

hvg(activeDocument.selection).each(
function setcolor  (obj){
		var CR = String.fromCharCode(13);
		var C = M = Y = K = "";
		C = "C =" + Math.round(obj.fillColor.cyan);
		M = "M =" + Math.round(obj.fillColor.magenta);
		Y = "Y =" + Math.round(obj.fillColor.yellow);
		K = "K =" + Math.round(obj.fillColor.black);
		//$.bp();
		myT = activeDocument.textFrames.add()
		myT.contents = (C+CR+M+CR+Y+CR+K);
		myT.left = obj.left+5;
		myT.top = obj.top-5;
}
);
