问题描述

如何在_.each循环的每次迭代中添加延迟，以便将内部函数的调用空间缩短1秒？

How can I add a delay inside each iteration of an _.each loop to space out the calling of an interior function by 1 second?

  _.each(this.rows, function (row, i) {
      row.setChars(msg[i] ? msg[i] : ' ');
  });

推荐答案

您不需要额外的IIFE

You don't need extra IIFE

_.each(this.rows, function (row, i) {
    setTimeout(function () {
        row.setChars(msg[i] ? msg[i] : ' ');
    }, 1000 * i);
});

因为你没有在显式的中为循环。

since you're not doing it in an explicit for loop.
