经过一段时间或满足条件后运行代码 [英] Run code after some time has passed or a condition is met

问题描述

编写代码的最佳方式和最干燥方式是什么，只要经过一段时间(例如5秒)或满足某些条件(例如，bool = true)，就可以执行-以先到者为准.从脚本第一次运行开始，将有五秒钟的时间开始计时，并且布尔值是由另一个函数更改的全局值.我认为您不能将超时和bool-check结合在一起使用，但是另一种好的方法也很好.

What is the best and DRYest way to write code that can be executed either when some time has passed (say, 5 seconds) or some condition is met (e.g. bool = true) - whichever comes first. The five seconds start counting from when the script first ran, and the boolean is a global that is changed by another function. I don't think you can combine the time out and the bool-check in one statement, but another good way is also good.

伪代码:

if (bool = true OR timePassed = 5000):
    runCode()

推荐答案

没有一个答案实际上提供了该问题的完整答案，即先到先得未实现-或最后一个代码运行两次.

None of the answers actually provide a full answer to the question, namely the whichever comes first is not implemented -- or the final code is run twice.

您需要一个计时器和一个条件(如其他答案所建议，但不能合并为一个整体).

You need a timer, and a condition (as other answers suggested but failed to combine in one whole).

var done = false;
var thisTimeout = setTimeout(function() {
    myFunction();
}, 1000);

if ((someCondition) && !done) {
    myFunction();
}
function myFunction() {
    clearTimeout(thisTimeout);
    done = true;
    // Do stuff
}
