jquery method to automatically scale images according to browser window size_jquery

The example in this article describes how jquery can automatically scale images according to the size of the browser window. Share it with everyone for your reference. The details are as follows:

(function($){
 $.fn.resizeimage = function(){
  var imgLoad = function (url, callback) {
   var img = new Image();
   img.src = url;
   if (img.complete) {
    callback(img.width, img.height);
   } else {
    img.onload = function () {
     callback(img.width, img.height);
     img.onload = null;
    };
   };
  };
  var original = {
   width:$(window).width()
  };
  return this.each(function(i,dom){
   var image = $(this);
   imgLoad(image.attr('src'),function(){
    var img = {
     width:image.width(),
     height:image.height()
    },percentage=1;
    if(img.width<original.width){
     percentage = 1;
    }else{
     percentage = (original.width)/img.width;
    }
    image.width(img.w=img.width*percentage-30).height(img.h=img.height*percentage);
    $(window).resize(function(){
     var w = $(this).width();
     percentage = w/img.width>1&#63;1:w/img.width;
     var newWidth = img.width*percentage-30;
     var newHeight = img.height*percentage;
     image.width(newWidth).height(newHeight);
    });
   });
  });
 };
})(jQuery);

I hope this article will be helpful to everyone’s jquery programming design.
