有没有人能够让 panzoom 的持续时间起作用? https://github.com/timmywil/jquery.panzoom

我进入源代码并将持续时间从 200 增加到 1200,当我调用缩放时没有看到变化。

 $panzoom.panzoom("zoom", 2.5);

更新

         var $section = $('section').first();
         $panzoom =  $section.find('.panzoom').panzoom({
            contain: false,
            minScale: 1,
            maxScale: 3,
            contain: true,  
            duration:1200
          }).panzoom('zoom', true);


$(elm).on('click' function(){

 $panzoom.panzoom("zoom", true);
});

为什么不直接用 option() 方法改变它呢?来自panzoom 文档:

// One at a time
// Sets the scale increment option
$elem.panzoom("option", "duration", 1200);

// Several options at once
$elem.panzoom("option", {
  increment: 0.4,
  minScale: 0.1,
  maxScale: 2,
  duration: 500,
  $reset: $("a.reset-panzoom, button.reset-panzoom")
});

您不必更改源中的任何默认值来设置不同的持续时间。

编辑:

如文档中所述,您需要给“缩放”一个布尔属性 true 以在选项中设置您自己的持续时间:

“如果方法传递一个布尔值,true 将指示根据选项中指定的增量执行缩小。如果为 false(或省略),将执行放大。”

下面是一个工作版本,我在选项(2500)中设置了自定义持续时间并使用了 panzoom(“zoom”,true):
