我正在尝试使用requestAnimationFrame创建具有滚动编号的javascript动画
In order to see the see the animation rolling, I need to use a $apply to refresh the view. The problem here is when I start the animation, the digest cycle is already running so my $apply return an error "$apply already in progress".
Looking for a solution I use $timeout of 0 which work perfectly but I was wondering if there was other solution to avoid using a timeout that is not really good in terms of performance? …
我第一次尝试使用React上下文API将信息从主要组件传递给他的孙组件。
到目前为止没有问题。一切正常。ChildComponent已检索到上下文值。
最后一个期望失败,并且上下文值是一个空对象。所以foo是不确定的
我在这里重新创建了问题:https : //codesandbox.io/embed/x25yop4x5w?fontsize=14
谢谢您的帮助
