如何使用 jquery 按比例调整图像大小以保持纵横比。基本上我想添加代码以根据调整后图像的比例调整顶部/左侧/宽度/高度

我试过这个：

$(window).bind('resize', function() {
    reposition();

    // add the code to adjust the top/left/width/height 
    // based on the ratio of the resized image
    var $carouselImg = $('.carouselImg');
    //alert($carouselImg.width());
    //alert($carouselImg.height());
    //code begin
    $('.carouselImg').each(function() {
        var maxWidth = 621; // Max width for the image
        var maxHeight = 584;    // Max height for the image
        var ratio = 0;  // Used for aspect ratio
        var width = $(this).width();    // Current image width
        var height = $(this).height();  // Current image height

        // Check if the current width is larger than the max
        if (width > maxWidth) {
            ratio = maxWidth / width;   // get ratio for scaling image
            $(this).css("width", maxWidth); // Set new width
            $(this).css("height", height * ratio);  // Scale height based on ratio
            height = height * ratio;    // Reset height to match scaled image
            width = width * ratio;    // Reset width to match scaled image
        }

        // Check if current height is larger than max
        if (height > maxHeight) {
            ratio = maxHeight / height; // get ratio for scaling image
            $(this).css("height", maxHeight);   // Set new height
            $(this).css("width", width * ratio);    // Scale width based on ratio
            width = width * ratio;    // Reset width to match scaled image
            height = height * ratio;    // Reset height to match scaled image
        }
    });

});

我在图像上有两个中心点（图像上的占位符指向两个不同的链接）。当我调整它们的大小时，它们也会缩小。我想在小型设备中查看时缩小图像。
