jQuery在页面加载时动态修改图片尺寸的方法

$(window).bind("load", function() {
  // IMAGE RESIZE
  $('#product_cat_list img').each(function() {
    var maxWidth = 120;
    var maxHeight = 120;
    var ratio = 0;
    var width = $(this).width();
    var height = $(this).height();
    if(width > maxWidth){
      ratio = maxWidth / width;
      $(this).css("width", maxWidth);
      $(this).css("height", height  ratio);
      height = height  ratio;
    }
    var width = $(this).width();
    var height = $(this).height();
    if(height > maxHeight){
      ratio = maxHeight / height;
      $(this).css("height", maxHeight);
      $(this).css("width", width  ratio);
      width = width  ratio;
    }
  });
  //$("#contentpage img").show();
  // IMAGE RESIZE
});
