Получается миниатюрный аналог JQuery.
loadImage - для HTML5 Canvas,
DOM - для манипуляции с элементами (не путать с JQuery).

DOM(document).event({"DOMContentLoaded":function(){
DOM(document.getElementById("canvas")).attr({
"width":"100",
"height":"100"
}).css({
"background-color":"rgb(255,0,0)"
});
}});

Сам скрипт:

(function(){
var global = (function(){return this;})();

global.DOM = function(element){
var elem = element;
var obj = {};

//Set Attributes
obj.attr = function(src){
  if(obj==null){obj={}}
  if(src==null){src={}}
  for(var i in src){
    elem.setAttribute(i,src[i]);
  }
  return obj;
}

//Set CSS
obj.css = function(src){
  if(obj==null){obj={}}
  if(src==null){src={}}
  for(var i in src){
    if(typeof elem.style.setProperty != "undefined"){
      elem.style.setProperty(i,src[i],null);
    } else {
      elem.style.setAttribute(i,src[i]);
    }
  }
  return obj;
}

//Event Attach
obj.event = function(obj){
  if(obj==null){obj={}}
  for(var i in obj){
    if(elem.addEventListener) {
      elem.addEventListener(i, obj[i], false);	
    } else
    if(elem.attachEvent) {
      elem.attachEvent('on' + i, function(e){func.call(obj[i], e);});
    }
  }
  return obj;
}

return obj;
};

global.loadImage = function(src,onload){
  var img = new Image();
  img.src = src;
  img.onload = onload;
  return img;
};

})();
