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>
</section>
</li>
<li>
<section class="focal">
<div class="parent">
<div class="panzoom">
<img src="http://www.patiocollection.com/images/D/971250B.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>
</section>
</li>

<section class="focal">
<div class="parent">
<div class="panzoom">
<img src="http://s3.amazonaws.com/images2.eprevue.net/p4dbimg/1375/images/ce0941_ext.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>
</section>
</li>
</ul>
</div>
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
});
答案 0 :(得分:2)
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)。
