我是FramerJS和Coffee Script的新手,但我不是编程的新手。我正在创建一些初学者项目,以了解FramerJS中的移动应用程序原型。我正在使用带有“卡片”的滚动应用程序。单击一张卡时,它应该缩放到屏幕大小。当你再次点击它时,它将回到它之前的帧位置。
然而,当点击任何卡片时,会发生什么情况,列表中的最后一张卡片是缩放到屏幕中心的卡片。我不确定到底发生了什么。任何人都可以看看代码,看看发生了什么?
提前致谢!

答案 0 :(得分:1)
在你的上一个循环中,你会为每张卡添加一个点击事件,如下所示:
for c in allCards
c.on Events.Click, (event, layer) ->
currentCard = c.copy()
currentCard.opacity = 1
currentCard.frame = c.screenFrame
c.animate
...
当循环结束时,全局变量c
被设置为allCards
数组中的最后一张卡并保持这种状态,因此当调用任何这些点击事件时,最后一张卡是一个被复制和动画的。
相反,一个选项是通过块中的本地layer
变量引用它:
for c in allCards
c.on Events.Click, (event, layer) ->
currentCard = layer.copy()
currentCard.opacity = 1
currentCard.frame = layer.screenFrame
layer.animate
...
在旁注中,当我期望它将是副本时,您正在设置原始图层的动画。这是你的意图吗?
希望这足以让你前进!
