<h2>bindWithDelay jQuery Plugin <a href='#example' style='float:right;'>(see example)</a></h2>
|
||
|
|
<h3>The Basics</h3>
|
||
|
|
<ul class='basics'>
|
||
|
|
<li><strong>What does bindWithDelay do?</strong>
|
||
|
|
It prevents a function call from happening EVERY time an event is fired from the browser.
|
||
|
|
Rather than implementing custom timeout code, just add in this plugin and simplify your code.
|
||
|
|
</li>
|
||
|
|
<li><strong>How do I use it in code?</strong>
|
||
|
|
<pre>Pretty much the same as <a href='http://api.jquery.com/bind/'>http://api.jquery.com/bind/</a>
|
||
|
|
element.bindWithDelay( eventType, [ eventData ], handler(eventObject), timeout, throttle )</pre>
|
||
|
|
It works with existing code that uses the bind() function.
|
||
|
|
Just add an extra parameter (timeout in milliseconds), and an optional boolean value if you would like to enable throttling.
|
||
|
|
<pre>// If your code that uses bind(), just add in a timeout parameter.
|
||
|
|
$("#element").bind("click", function() {...});
|
||
|
|
$("#element").<span class='key'>bindWithDelay</span>("click", function() {...}, <span class='key'>1000</span>);
|
||
|
|
|
||
|
|
// If your code that uses click(), you will need to do it the same way.
|
||
|
|
$("#element").click(function() {...}, 1000);
|
||
|
|
$("#element").<span class='key'>bindWithDelay</span>("click", function() {...}, <span class='key'>1000</span>);
|
||
|
|
|
||
|
|
// If you would like to let it still fire once per interval while an event is fired
|
||
|
|
// (called "throttling"), then put a true in for the throttle parameter:
|
||
|
|
$("#element").<span class='key'>bindWithDelay</span>("click", function() {...}, <span class='key'>1000</span>, true);
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
</li>
|
||
|
|
<li><strong>Where is the source code?</strong> <br />
|
||
|
|
<a href="http://github.com/bgrins/bindWithDelay/blob/master/bindWithDelay.js">http://github.com/bgrins/bindWithDelay/blob/master/bindWithDelay.js</a>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<h3>What is the difference between throttling and not?</h3>
|
||
|
|
<p>Imagine you are scrolling down a long page for 3 seconds and you have bindWithDelay running with a timeout of 1000ms. By default, your event will only fire a second after you have completely finished scrolling. If you have the optional throttling on, it will fire once per second during the scrolling - a total of 3 times instead of 1. Move your mouse around in circles and look at the example below to see:</p>
|
||
|
|
<a name="example"></a>
|
||
|
|
<h3>A Simple Example</h3>
|
||
|
|
<p>As you have been on this page, it has been tracking how many times your browser's mousemove, click,
|
||
|
|
scroll, and resize events have fired (both with and without bindWithDelay).
|
||
|
|
Go ahead and move your mouse around and click (try clicking a bunch of times in a row to see what it does)
|
||
|
|
, or resize your browser to get a look at how it works.</p>
