Question

HTML和Javascript

<section>
     <h1>Panning and zooming with CSS3</h1>

    <div class="parent">
        <div class="panzoom">
            <img src="image1" width="400" height="400">
        </div>
    </div>
    <div class="buttons">
        <button class="zoom-in">Zoom In</button>

        <input type="range" class="zoom-range">
        <button class="reset">Reset</button>
    </div>
    <script>
        (function() {
            var $section = $('section').first();
            $section.find('.panzoom').panzoom({
                $zoomIn: $section.find(".zoom-in"),
                $zoomOut: $section.find(".zoom-out"),
                $zoomRange: $section.find(".zoom-range"),
                $reset: $section.find(".reset")
            });
        })();
    </script>
</section>

我在用Pan插件。

如何限制Zoomout功能。我的意思是，我想放大图像到一定大小的图像，比如100 px。

Demo http://timmywil.github.io/jquery.panzoom/demo/#inverted-contain

我试过了演示版的Inverted containment within the parent element (to hide what's behind)。但对我来说不起作用。请帮帮忙。

Answer 1

我知道这很古老，但是如果你玩minScale，你可以得到你喜欢的东西。您可以阅读自述文件的文档：

Answer 2

试试这个，这个会对你有用的

 (function() {
    var $section = $('section').first();
    $section.find('.panzoom').panzoom({
      increment: 0.3,
      minScale: 0.8,
      maxScale: 1.3
  });
