<p>Click the button to see how many attributes the img element have.</p>

<button onclick="myFunction()">Try it</button>
​
<p>The result should be 5 (the img element's id, alt, src, width and height attributes).</p>
​
<p><strong>Note:</strong> In Internet Explorer 8 and earlier, the attributes property will return a collection of all <em>possible</em> attributes for the element, and will, in this example, display a much higher number than 5 (possibly 134).</p>
