我想在useEffect中的状态更改后调度操作

React.useEffect(() => {
    let timer = setInterval(() => {
      setCurrTime(activeCallTime());
      /**
       @todo:dispatch currtime action  
      **/
    }, 1000);
    
    return () => clearInterval(timer);
  }, [props.startTime]);

redux

请尝试此解决方案

React.useEffect(() => {
        let timer = setInterval(() => {
          setCurrTime(activeCallTime());
        }, 1000);
        
        return () => clearInterval(timer);
      }, [props.startTime]); 

React.useEffect(() => {
    dispatch the action  
 }, [currTime]);

React.useEffect(() => {
    let timer = setInterval(() => {
     let temp = activeCallTime() 
     setCurrTime(temp);
      //dispatch temp
    }, 1000);
    
    return () => clearInterval(timer);
  }, [props.startTime]);
