// example:
// checkEach(1000, () => {
//   if(!canIDoWorkNow()) {
//     return true // try again after 1 second
//   }
//
//   doWork()
// })
export function checkEach(milliseconds, fn) {
  const timer = setInterval(
    () => {
      try {
        const retry = fn()

        if (retry !== true) {
          clearInterval(timer)
        }
      } catch (e) {
        clearInterval(timer)

        throw e
      }
    },
    milliseconds
  )
}

更好地使用jAndy的答案来实现一个轮询函数，该函数每间隔秒轮询一次，并在超时秒后结束。

function pollFunc(fn, timeout, interval) {
    var startTime = (new Date()).getTime();
    interval = interval || 1000;

    (function p() {
        fn();
        if (((new Date).getTime() - startTime ) <= timeout)  {
            setTimeout(p, interval);
        }
    })();
}

pollFunc(sendHeartBeat, 60000, 1000);

更新

根据注释，将其更新为传递函数停止轮询的能力:

function pollFunc(fn, timeout, interval) {
    var startTime = (new Date()).getTime();
    interval = interval || 1000,
    canPoll = true;

    (function p() {
        canPoll = ((new Date).getTime() - startTime ) <= timeout;
        if (!fn() && canPoll)  { // ensures the function exucutes
            setTimeout(p, interval);
        }
    })();
}

pollFunc(sendHeartBeat, 60000, 1000);

function sendHeartBeat(params) {
    ...
    ...
    if (receivedData) {
        // no need to execute further
        return true; // or false, change the IIFE inside condition accordingly.
    }
}

有两种方法叫-

setInterval(function (){functionName();}， 60000); setInterval (functionName, 60000);

以上函数将每60秒调用一次。

您可以简单地在函数末尾调用setTimeout。这将再次将其添加到事件队列中。您可以使用任何类型的逻辑来改变延迟值。例如,

function multiStep() {
  // do some work here
  blah_blah_whatever();
  var newtime = 60000;
  if (!requestStop) {
    setTimeout(multiStep, newtime);
  }
}

使用窗口。setInterval(函数、时间)。

Call a Javascript function every 2 second continuously for 10 second. var intervalPromise; $scope.startTimer = function(fn, delay, timeoutTime) { intervalPromise = $interval(function() { fn(); var currentTime = new Date().getTime() - $scope.startTime; if (currentTime > timeoutTime){ $interval.cancel(intervalPromise); } }, delay); }; $scope.startTimer(hello, 2000, 10000); hello(){ console.log("hello"); }
