我有一个障碍，那就是如果我按下取消订单按钮（batalkan pesanan），那么就会出现无限循环，为什么要使用componentdidupdate来更新新显示，或者除了componentdidupdate之外还有更好的方法？
在按取消命令之前（batalkan pesanan
发生无限循环
该功能是在按取消订单（batalkan pesanan）按钮后更新是否显示以下图像

最佳答案
您正在陷入无限循环，因为您正在在setState中调用的函数内部调用componentDidUpdate。
在setState中调用componentDidUpdate总是会导致重新渲染
为了减轻这种情况，您应该将要调用的函数包含在条件表达式中。
componentDidUpdate(prevProps, prevState) {
// yourConditionalExpression can be any of the following:
// this.props.yourPropName !== prevProps.yourPropName
// this.state.yourStateVariable !== prevState.yourStateVariable
if (yourConditionalExpression) {
this.productOrderTabsNotYetPay();
}
}
