我想延迟缩放的图像消失X秒，这样我就可以淡出图像，而不是简单地消失。
我可以简单地将 .delay（1000）添加到mouseleave / hide代码行吗？
我试过了，但不幸的是似乎没有用。我还尝试在代码的各个部分周围包装 setTimeout（...，1000）; ，但也无法使其工作。
非常感谢任何帮助！
这是Jsfiddle https://jsfiddle.net/mr_antlers/nh5jw5tb/2/
这是原始的'EasyZoom'.js代码。

实例化时，您可以将beforeShow和beforeHide参数传入easyZoom。
var $easyzoom = $('.easyzoom').easyZoom({
beforeHide: function() {
this.$flyout.fadeOut();
return false;
},
beforeShow: function() {
this.$flyout.show();
}
});

您可以在函数中使用this.$flyout来引用弹出式缩放图像。
如果要停止默认的hide或show功能，则返回false。如果您正在这样做，请记住将默认行为添加到您的函数中。
在上面的示例中，我对缩放的图像执行了fadeOut并停止弹出分离（默认行为是detach()缩放的图像元素）。然后，当弹出元素淡出时，我必须使用$.show()，否则该元素将被卡在display: none，鼠标悬停时不会显示任何内容。
希望这有帮助。
答案 1 :(得分：0)
＆＃39;鼠标离开＆＃39;触发_onLeave（）导致带有图像的缩放div的fire hide（）从DOM中删除，因此任何CSS转换或$（）。fadeOut（）都不起作用。我在mouseleave中删除了hide（）触发并改变了CSS中的不透明度，它似乎现在正常工作，其他任何东西似乎都被打破了。根据需要更改不透明度时间。
