Get mouse location during mouse down?
<p>How can I continuously get the position of the mouse whilst its button is being held down?</p>

<p>I know I can do:</p>

<pre><code>&lt;element onclick="functionName(event)"&gt;&lt;/element&gt;
&lt;script&gt;
function functionName(e){
e.pageX
e.pageY
//do stuff
}
&lt;/script&gt;
</code></pre>

<p>and I know you can use the onmousedown event, but how would I continuously get the position while the button is still held down? </p>

<p>Oddly I couldn't find this anywhere I looked.</p>
