$.delay is used to delay animations in a queue, not halt execution.

Instead of using a while loop, you need to recursively call a method that performs the check every second using <code>setTimeout</code>:

<pre><code>var check = function(){
 if(condition){
 // run when condition is met
 }
 else {
 setTimeout(check, 1000); // check again in a second
 }
}

check();
</code></pre>

blocks|key|462222|text|你也可以这样延迟一些操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|462223|setTimeout(function+(){

You can also just delay some operation this way:

<pre><code>setTimeout(function (){

 // Something you want delayed.

}, 5000); // How long do you want the delay to be (in milliseconds)? 
</code></pre>

blocks|key|677244|text|jQuery的delay函数旨在与效果和效果队列一起使用，请参阅delay+docs和其中的示例：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|677245|$('#foo').slideUp(300).delay(800).fadeIn(400);|code-block|syntax|javascript|677246|如果你想观察一个变量的变化，你可以这样做|677247|(function()+{

jQuery's <code>delay</code> function is meant to be used with effects and effect queues, see the <a href="http://api.jquery.com/delay/" rel="noreferrer"><code>delay</code> docs</a> and the example therein:

<pre><code>$('#foo').slideUp(300).delay(800).fadeIn(400);
</code></pre>

If you want to observe a variable for changes, you could do something like

<pre><code>(function() {
 var observerInterval = setInterval(function() {
 if (/* check for changes here */) {
 clearInterval(observerInterval);
 // do something here
 }
 }, 1000);
})();
</code></pre>

blocks|key|677152|text|JavaScript+setTimeout是一个非常好的解决方案：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|677153|function+funcx()
+++{
+++//+your+code+here
+++//+break+out+here+if+needed
+++setTimeout(funcx,+3000);
+++}

funcx();|code-block|syntax|javascript|677154|jQuery中的delay函数主要用于延迟jQuery动画队列中的动画。|677155|entityMap^0|B|A|0|0|8|5|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|S|8|@$9|T|A|U|B|C]]|D|@]|E|$]]|$1|M|3|-4|5|6|7|V|8|@]|D|@]|E|$]]]|N|$]]

JavaScript <code>setTimeout</code> is a very good solution:

<pre><code>function funcx()
 {
 // your code here
 // break out here if needed
 setTimeout(funcx, 3000);
 }

funcx();
</code></pre>

The <code>delay</code> function in jQuery is mostly used for delaying animations in a jQuery animation queue.

blocks|key|677191|text|delay()不会停止代码流，然后重新运行它。在JavaScript中没有实际的方法可以做到这一点。所有的事情都必须通过接受回调的函数来完成，比如其他人提到的setTimeout。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|677192|jQuery的delay()的目的是让动画队列在执行之前等待。因此，例如，$(element).delay(3000).fadeIn(250);将使元素在3秒后淡入。|677193|entityMap^0|0|7|27|A|0|7|7|11|Z|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|O|8|@$9|P|A|Q|B|C]|$9|R|A|S|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|I|$]]

<code>delay()</code> doesn't halt the flow of code then re-run it. There's no practical way to do that in JavaScript. Everything has to be done with functions which take callbacks such as <code>setTimeout</code> which others have mentioned.

The purpose of jQuery's <code>delay()</code> is to make an animation queue wait before executing. So for example <code>$(element).delay(3000).fadeIn(250);</code> will make the element fade in after 3 seconds.

blocks|key|462187|text|Javascript是一种异步编程语言，因此您不能在一段时间内停止执行；您可以伪停止执行的唯一方法是使用setTimeout()，它不是延迟，而是“延迟的函数回调”。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|462188|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Javascript is an asynchronous programming language so you can't stop the execution for a of time; the only way you can [pseudo]stop an execution is using setTimeout() that is not a delay but a "delayed function callback".

Only javascript It will work without jQuery 

<pre><code>&lt;!DOCTYPE html&gt;
&lt;html&gt;
 &lt;head&gt;
 &lt;script&gt;
 function sleep(miliseconds) {
 var currentTime = new Date().getTime();
 while (currentTime + miliseconds &gt;= new Date().getTime()) {
 }
 }

 function hello() {
 sleep(5000);
 alert('Hello');
 }
 function hi() {
 sleep(10000);
 alert('Hi');
 }
 &lt;/script&gt;
 &lt;/head&gt;
 &lt;body&gt;
 &lt;a href="#" onclick="hello();"&gt;Say me hello after 5 seconds &lt;/a&gt;
 &lt;br&gt;
 &lt;a href="#" onclick="hi();"&gt;Say me hi after 10 seconds &lt;/a&gt;


 &lt;/body&gt;
&lt;/html&gt;
</code></pre>

this code work well for me.

I can't get the <code>.delay</code> method working in jQuery:

<pre><code>$.delay(3000); // not working
$(queue).delay(3000); // not working
</code></pre>

I'm using a while loop to wait until an uncontrolled changing value is greater than or equal to another and I can't find any way to hault execution for X seconds.

我无法在jQuery中使用.delay方法：$.delay(3000); // not working$(queue).delay(3000); // not working我使用一个while循环来等待，直到一个不受控制的变化值大于或等于另一个值，并且我找不到任何方法在X秒内停止执行。
