转到“下一步" JavaScript forEach循环中的迭代 [英] Go to "next" iteration in JavaScript forEach loop

问题描述

如何进入JavaScript Array.forEach()循环的下一个迭代?

How do I go to the next iteration of a JavaScript Array.forEach() loop?

例如:

var myArr = [1, 2, 3, 4];

myArr.forEach(function(elem){
  if (elem === 3) {
    // Go to "next" iteration. Or "continue" to next iteration...
  }

  console.log(elem);
});

MDN文档仅提及完全脱离循环，不进行下一个迭代.

MDN docs only mention breaking out of the loop entirely, not moving to next iteration.

推荐答案

如果要跳过当前迭代，可以简单地return.

You can simply return if you want to skip the current iteration.

由于您处于函数中，因此如果在执行其他任何操作之前先执行return，则实际上已经跳过了return语句下面的代码的执行.

Since you're in a function, if you return before doing anything else, then you have effectively skipped execution of the code below the return statement.
