})(Zepto)

$.fn.imageloader = function(){
	 this.each(function(ind,ele){
			 var imgSrc = ele.getAttribute('data-src');
			 if(!imgSrc) return;
			 var img = $('<img>').attr('src', imgSrc);		  
       onload = function(){
				 	ele.src =  imgSrc;
				 	delete img;
			 }; 
       onload.call(img[0].onload);
	});
}

jquery 也可以哦。

<script type="text/javascript" crossorigin>
//全局代码异常收集
window.onerror = function (msg, url, lineNo, columnNo, error) {
  var error = 'Error: ' + msg + ' Script: ' + url + ' Position:[' + lineNo + ' / ' + columnNo+ ']StackTrace: ' +  error;
  try{
      $.ajax({url:"http://myhost.com",async:true,dataType:'jsonp',cache:false,data:{"error":error}});
  }catch (error){}
  return false;
};
</script>

//var en = encodeURI('<script src="http://cdn.bootcss.com/jquery/3.2.0/jquery.min.js" type="text/javascript"></script>');

//把上面的en结果填写到下面的en中，才能写入成功。奇怪？？？？？？？？？

document.write(unescape(en));
