如何退出（转义）从循环里面的功能呢？ [英] How to exit (escape) a function from for loop inside of it?

问题描述

我对此感到困惑，因为我是这样理解的卡在代码
如何逃避for ...每个循环和方法在同一时间？

我不能停止迭代选项在中选择元素。

我试过返回和返回false 已经是，但是我没有成功。

一般我们可以做什么（）...

$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ ）{
$（...）。each（function（）{
//你必须从这里退出外部函数
}）;




$ div class =h2_lin>解决方案

在循环之间使用共享变量。如果你想退出，在 each（）循环的末尾将它翻转为 true for-loop 检查它是 true 。如果是的话，打破它。

This is theoretical question to understand how many escapes (return or exit) can apply to nested loops or other controls and functions.

I confused about this because I am stuck in the code How to escape from for ... each loop and method at the same time?

I can't stop iterating over options in select element.

I tried return and return false already, but am unsuccesful.

Generally how we can do that?

function() {
    for (...) {
        if (...) {
            $(...).each(function() {
               // You have to exit outer function from here
            });
        }
    }
}

解决方案

Use a shared variable between the loops. Flip it to true at the end of the each() loop if you want to exit and at the end of the for-loop check for it being true. If yes, break out of it.
