<p>If you need to delay for debugging purposes, you will need to add <code>debugger;</code> statements to your code. When you add debugger and have your developer tools open, script execution will pause at your <code>debugger;</code> statement and you can inspect your code in the developer tools.</p>

<pre><code>console.log('I will execute');
debugger; // execution will pause at this line
console.log("I won't execute until you say so");
</code></pre>

<p>If you need to delay execution for your site behavior, you can use <code>setTimeout()</code> to delay invocation.</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>console.log('I will be printed immediately');
setTimeout(function() {
  console.log('I will be printed after 5s');
}, 5000); // 5s delay</code></pre>
</div>
</div>
</p>

<p>I need to execute a Javascript in the console of Chrome with some delay. How can this be done?</p>

<p>The reason I need this is that as soon the focus changes from the webpage (or a certain element of the webpage) it is redrawn. Therefore I want to start the script I execute in the console with a few seconds delay so I can change the focus to the right element on the page I am working with.</p>

<p>Edit 1: Dinesh Padiyan.</p>

<p>Doesn't work for me, se screen shot:</p>

我需要在Chrome的控制台上执行Javascript，并有一些延迟。这是如何做到的呢？我需要这样做的原因是，一旦焦点从网页(或网页的某个元素)改变，它就会被重新绘制。因此，我希望在控制台中启动脚本，延迟几秒钟，这样我就可以将焦点更改为正在处理的页面上的正确元素。编辑1: Dinesh Padiyan。不适合我，屏幕截...
