有没有人能够让panzoom的持续时间发挥作用? https://github.com/timmywil/jquery.panzoom
我进入源代码并将持续时间从200增加到1200,并且在调用缩放时没有看到更改。
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);
});

为什么不用option()方法更改它?来自panzoom docs:
// 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")
});
您不必更改来源中的任何默认设置以设置不同的持续时间。
编辑:
你需要提供" zoom"布尔属性为true,用于在选项中设置您自己的持续时间,如文档中所述:
"如果方法传递了一个布尔值,则true表示根据options中指定的增量执行缩小。如果为false(或省略),则将执行放大。"
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("缩放",true):
