我写的这个东西,怎么改成对象形式?

Question

var l = [];for (i=0; i<app.activeDocument.layers.length;i++)  {    l[i] =[0,0,"0"] ;    var a = app.activeDocument.layers[i];    var ybl = new ybLayer( a ) ;    //( 图层对象 )    l[i][0] = ybl.ybLeftTopY;    l[i][1] = ybl.ybHeight;    l[i][2] = app.activeDocument.layers[i].name ;}
