Determine scroll position while using overflow

JavaScript
1

i have a list that has a set height of 100 pixels. the overflow property is set to ‘auto’, that way a scroll bar appears if the list gets too crowded.

<ul style="height: 100px; overflow: auto;">
     <li>Testing</li>
     <li>Testing</li>
     <li>Testing</li>
     <li>Testing</li>
     <li>Testing</li>
     <li>Testing</li>
     <li>Testing</li>
</ul>

i’m wanting a way to reset the scroll position to the top of the list. anyone know how i can do this? thanks!

The scrollTop property is what you’re after

.scrollbox {
    height: 100px;
	overflow: auto;
}



<ul id="myScrollbox" class="scrollbox">
     <li>Testing</li>
     <li>Testing</li>
     <li>Testing</li>
     <li>Testing</li>
     <li>Testing</li>
     <li>Testing</li>
     <li>Testing</li>
</ul>
<p><input id="scrollTop" type="button" value="Scroll to top"></p>



function scrollToTop(el) {
	el.scrollTop = 0;
}
document.getElementById('scrollTop').onclick = function () {
	var el = document.getElementById('myScrollbox');
    scrollToTop(el);
};
