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});
