怎么判断AJAX取回来的DOM树数据中的图片等信息已经全部加载完成
怎么判断AJAX取回来的DOM树数据中的图片等信息已经全部加载完成,因为现在有个需求要在插入DOM树后取得该对象的scrollHeight高度值,如果里面的图片还没有加载完成就取则不能得到准确的值。求高手帮忙解答,跪谢!!!

------解决方案--------------------
JScript code
var imgList = $(yourDom).find('img');

var callback = function(){
  alert('全部图片下载完毕!');
};

var check = (funciton(count, fn){
  return function(){
    count--;
    if(count == 0){
       fn();
    }
  };
})(imgList.length, callback);

imgList.each(function(){
  $(this).bind('load', check)
         .attr(src, $(this).attr('src'));
});
