$(document).ready()|| setTimeout? [英] $(document).ready() || setTimeout?

问题描述

我有代码(对于问题来说不是必需的)，需要在$(document).ready()或之后执行，如果窗口加载了5秒钟.

I have code (not necessary for the question) which needs to be executed after $(document).ready() or if the window is loaded for let's say 5 seconds.

我试图弄清楚，但是我在网上找不到任何东西.希望这里有人能帮助我！

I tried to figure it out, but I couldn't find anything on the web. Hope someone here can help me!

(我知道如何像2条语句一样将其分开，但是我需要将其放在OR语句中.)

(I know how to do it separate like in 2 statements, but I need to put it in a OR statement.)

使人们更清楚. 等待，直到文档准备就绪，也可以建立域或，如果在5秒钟后文档仍未准备好，但窗口已加载，则只需执行该功能即可. >

To make it more clear for people. Either wait till the document is ready aka dom is builded OR if after 5 seconds the document still isn't ready BUT the window is loaded, just execute the function.

推荐答案

使用setTimeout安排操作，然后将clearTimeout放在$(document).ready()中以取消该操作(如果文档准备得更快).

Use setTimeout to schedule the operation, then put clearTimeout in $(document).ready() to cancel it if the document becomes ready sooner.

并使用一个变量来判断该函数是否已由计时器运行，因此您无需在ready函数中再次进行此操作.

And use a variable to tell if the function has already been run by the timer, so you don't do it again in the ready function.

var functionDone = false;
var timeout = setTimeout(function() {
    someFunction();
    functionDone = true;
}, 5000);
$(document).ready(function() {
    if (!functionDone) {
        clearTimeout(timeout);
        someFunction();
    }
});
