Question

如何每10次循环等待1或2分钟？

例如，这是我的工作代码：

var dates = ["2016-08-31T23:00:00.000Z","2016-09-01T23:00:00.000Z","2016-09-02T23:00:00.000Z","2016-09-03T23:00:00.000Z","2016-09-04T23:00:00.000Z","2016-09-05T23:00:00.000Z","2016-09-06T23:00:00.000Z","2016-09-07T23:00:00.000Z","2016-09-08T23:00:00.000Z","2016-09-09T23:00:00.000Z","2016-09-10T23:00:00.000Z","2016-09-11T23:00:00.000Z","2016-09-12T23:00:00.000Z","2016-09-13T23:00:00.000Z","2016-09-14T23:00:00.000Z","2016-09-15T23:00:00.000Z","2016-09-16T23:00:00.000Z","2016-09-17T23:00:00.000Z","2016-09-18T23:00:00.000Z","2016-09-19T23:00:00.000Z","2016-09-20T23:00:00.000Z","2016-09-21T23:00:00.000Z","2016-09-22T23:00:00.000Z","2016-09-23T23:00:00.000Z","2016-09-24T23:00:00.000Z","2016-09-25T23:00:00.000Z","2016-09-26T23:00:00.000Z","2016-09-27T23:00:00.000Z","2016-09-28T23:00:00.000Z","2016-09-29T23:00:00.000Z","2016-09-30T23:00:00.000Z","2016-10-01T23:00:00.000Z"];

var counter = 0;

// Loop the dates and convert them to this format: yyyy-m-d
dates.forEach(function(date, index) {
    counter ++;

    console.log(date);

    // Reset when you reach 10 counts.
    if (counter === 10) {
        counter = 0;
    }

    // Wait for 2 minute before the next 10 loop.
    setTimeout( function() {
       //
    }, 120000);
});

有可能吗？有什么想法吗？

Answer 1

尝试在setTimeout函数中每分钟执行一次想要执行的函数。此外，如果要执行多次，则应将setTimeout替换为setInterval

setInterval( function() {
   dates.forEach(function(date, index) {
      counter ++;

      // Reset when you reach 10 counts.
      if (counter === 10) {
       counter = 0;
      }
   }
}, 120000);

Answer 2

您可以使用setInterval并在for循环内部在每个时间间隔内增加10。

      var date = dates[i].slice(0, 10);
      console.log(date)

  c += 10

  if (c >= dates.length) clearInterval(x)

loopDates()
var x = setInterval(loopDates, time)

Answer 3

您可以在超时时间内拥有变量。当计数器达到10时，将其值设置为120000。并确保在IIFE中包含settimeout（立即调用函数表达式）。因此，对于特定指数的那段时间，它将等待2分钟＆amp;然后用下一个索引继续循环。
