Question

我从插件中得到以下代码。这是一个Picture Zoomer，并将图像宽度设置为100％;和高度为320px。他们已将这些值作为参数传递。宽度的默认值为320px。然后我将此宽度转换为100％。问题是，在将宽度转换为百分比之后（因为我在响应环境中构建它），1。缩放图像未显示其全宽，以及2.当我将光标悬停在图像上时，我必须移动到图像的最左侧才能看到预览。在这方面的任何帮助将不胜感激。这是代码段。

;(function($){
    $.fn.picZoomer = function(options){
        var opts = $.extend({}, $.fn.picZoomer.defaults, options), 
            $this = this,
            $picBD = $('<div class="picZoomer-pic-wp"></div>').css({'width':opts.picWidth+'%', 'height':opts.picHeight+'px'}).appendTo($this),
            $pic = $this.children('img').addClass('picZoomer-pic').appendTo($picBD),
            $cursor = $('<div class="picZoomer-cursor"><i class="f-is picZoomCursor-ico"></i></div>').appendTo($picBD),
            cursorSizeHalf = {w:$cursor.width()/2 ,h:$cursor.height()/2},
            $zoomWP = $('<div class="picZoomer-zoom-wp"><img src="" alt="" class="picZoomer-zoom-pic"></div>').appendTo($this),
            $zoomPic = $zoomWP.find('.picZoomer-zoom-pic'),
            picBDOffset = {x:$picBD.offset().left,y:$picBD.offset().top};


        opts.zoomWidth = opts.zoomWidth||opts.picWidth;
        opts.zoomHeight = opts.zoomHeight||opts.picHeight;
        var zoomWPSizeHalf = {w:opts.zoomWidth/2 ,h:opts.zoomHeight/2};


        $zoomWP.css({'width':opts.zoomWidth+'px', 'height':opts.zoomHeight+'px'});
        $zoomWP.css(opts.zoomerPosition || {top: 0, left: opts.picWidth+30+'px'});

        $zoomPic.css({'width':opts.picWidth*opts.scale+'px', 'height':opts.picHeight*opts.scale+'px'});


        $picBD.on('mouseenter',function(event){
            $cursor.show();
            $zoomWP.show();
            $zoomPic.attr('src',$pic.attr('src'))
        }).on('mouseleave',function(event){
            $cursor.hide();
            $zoomWP.hide();
        }).on('mousemove', function(event){
            var x = event.pageX-picBDOffset.x,
                y = event.pageY-picBDOffset.y;

            $cursor.css({'left':x-cursorSizeHalf.w+'px', 'top':y-cursorSizeHalf.h+'px'});
            $zoomPic.css({'left':-(x*opts.scale-zoomWPSizeHalf.w)+'px', 'top':-(y*opts.scale-zoomWPSizeHalf.h)+'px'});

        });
        return $this;

    };
    $.fn.picZoomer.defaults = {
        picWidth: 100,
        picHeight: 320,
        scale: 2.5,
        zoomerPosition: {top: '0', left: '350px'}
        /*,
        zoomWidth: 320,
        zoomHeight: 320*/
    };
})(jQuery);
