Vue.js 过渡和效果乱序执行
Vue.js Transitions and effects executing out of order
我正在制作井字游戏网络应用程序。它还没有完成,因为这个问题已经抛出了障碍。当 X 或 O 获胜时,它应该将 3 个获胜框变为绿色(如果我删除了我希望在那之后发生的过渡,这部分工作)。一旦框为绿色,整个 'Board' table 应该 'bounce out'。但实际发生的情况是,'Board' 在 'mark' (X/O) 显示之前跳出并且获胜框变为绿色。对我来说没有意义的是,代码执行的重点应该是从上到下,但它的行为似乎并不像那样。我试过用几种不同的方式重新排列代码,但仍然没有成功。
这里是为那些不想点击 link 的人准备的代码 :P(抱歉样式问题,代码片段无法正常工作 =/
顺便说一句,提前致谢!

您的代码作为一个块运行; UI 不会在您的设置 active
和 over
之间重绘,因此就 UI 而言,它们同时有效地发生。 over
触发了 v-if
绑定,所以内容不会被重新绘制,它们只是过渡出来。
Vue 提供 nextTick
让您可以对事物进行排序。与 setTimeout(..., 0)
一样,它将您的命令带出块,但它确保在执行之前发生 DOM 更新周期。
