<div class="longdesc">
<p>The <code>.removeAttr()</code> method uses the JavaScript <code>removeAttribute()</code> function, but it has the advantage of being able to be called directly on a jQuery object and it accounts for different attribute naming across browsers.</p>
<p><strong>Note:</strong> Removing an inline <code>onclick</code> event handler using <code>.removeAttr()</code> doesn't achieve the desired effect in Internet Explorer 6, 7, or 8. To avoid potential problems, use <code>.prop()</code> instead:</p>
<pre>
$element.prop("onclick", null);
console.log("onclick property: ", $element[0].onclick);
</pre>
<p>The behavior of <code>.removeAttr()</code> may be updated to better handle this in the future. For the time being, however, setting <code>.prop("onclick", null)</code> should be considered the standard cross-browser solution.</p>
