如何在 jQuery.each() util 中跳到下一次迭代? [英] How to skip to next iteration in jQuery.each() util?

问题描述

我正在尝试遍历一个元素数组.jQuery 的文档说:

I'm trying to iterate through an array of elements. jQuery's documentation says:

jquery.Each() 文档

返回非false与for循环中的continue语句相同，会立即跳到下一次迭代.

Returning non-false is the same as a continue statement in a for loop, it will skip immediately to the next iteration.

我试过调用'return non-false;'和非假"；(无返回)两者都不会跳到下一次迭代.相反，他们打破了循环.我错过了什么?

I've tried calling 'return non-false;' and 'non-false;' (sans return) neither of which skip to the next iteration. Instead, they break the loop. What am i missing?

推荐答案

他们所说的non-false是指:

What they mean by non-false is:

return true;

所以这段代码:

var arr = ["one", "two", "three", "four", "five"];
$.each(arr, function(i) {
  if (arr[i] == 'three') {
    return true;
  }
  console.log(arr[i]);
});
