<p class="arguement"><strong>duration</strong>An integer indicating the number of milliseconds to delay execution of the next item in the queue.</p>
|
|
<p class="arguement"><strong>queueName</strong>A string containing the name of the queue. Defaults to <code>fx</code>, the standard effects queue.</p>

|
|
<p>Added to jQuery in version 1.4, the <code>.delay()</code> method allows us to delay the execution of functions that follow it in the queue. It can be used with the standard effects queue or with a custom queue. </p>
|
|
<p>Durations are given in milliseconds; higher values indicate slower animations, not faster ones. The strings <code>'fast'</code> and <code>'slow'</code> can be supplied to indicate durations of 200 and 600 milliseconds, respectively.</p>
|
|
<p>Using the standard effects queue, we can, for example, set an 800-millisecond delay between the <code>.slideUp()</code> and <code>.fadeIn()</code> of <code><div id="foo"></code>:</p>
|
|
<pre>$('#foo').slideUp(300).delay(800).fadeIn(400);</pre>
|
|
<p>When this statement is executed, the element slides up for 300 milliseconds and then pauses for 800 milliseconds before fading in for 400 milliseconds.</p>
|
|
<p><strong>jQuery.delay() is best for delaying between queued jQuery effects and such, and is not a replacement for JavaScript's native <a href="https://developer.mozilla.org/en/DOM/window.setTimeout">setTimeout</a> function, which may be more appropriate for certain use cases.</strong></p>
