我使用了panzoom jquery和bxSlider。问题是,在使用滚动进行缩放时,它不会放大中心。缩放可以左侧或右侧由于滑块,否则它可以正常工作。

在此处找到 fiddle demo

<div class="slider">    
        <ul class="bxSlider">
            <li>
                <section class="focal">
                    <div class="parent">
                        <div class="panzoom">
                            <img src="https://rockwoodtables.files.wordpress.com/2012/06/table-4.jpg" width="1000" height="450" />
                        </div>
                    </div>
                    <div class="buttons">
                        <button class="zoom-in">Zoom In</button>
                        <button class="zoom-out">Zoom Out</button>
                        <input type="range" class="zoom-range" />
                        <button class="reset">Reset</button>
                    </div>

                        <input type="range" class="zoom-range" />
                        <button class="reset">Reset</button>

js

 (function() {
    var $section = $('.focal');
    var $panzoom = $section.find('.panzoom').panzoom({
        $zoomIn: $section.find(".zoom-in"),
        $zoomOut: $section.find(".zoom-out"),
        $zoomRange: $section.find(".zoom-range"),
        $reset: $section.find(".reset"),
        $set: $section.find('.parent > div')
    });
    $panzoom.parent().on('mousewheel.focal', function( e ) {
      e.preventDefault();
      var delta = e.delta || e.originalEvent.wheelDelta;
      var zoomOut = delta ? delta < 0 : e.originalEvent.deltaY > 0;
      $panzoom.panzoom('zoom', zoomOut, {
        increment: 0.1,
        animate: false,
        focal: e
      });
    });

  })();

  $('.bxSlider').bxSlider({
        auto:true,
        autoHover: true,
        speed:1800,
        controls: true,
        pager: false,
        pause: 10000
    });

你的问题本身不是滑块。您只需选择具有相同类.focal的多个元素(部分)。

Panzoom旨在用于单个元素。所以我们只需要创建一个函数并用each()遍历每个元素。现在我们可以每次调用函数,将panzoom()方法绑定到每个元素(单独)。
