How to Prevent Scrolling the Entire Page When Clicking an Element Inside a Scrollable Div?

How to Scroll Within a Scrollable Div

When clicking on an element within a scrolled div, you may encounter an issue where the entire page scrolls instead of just the div. To resolve this, leverage the following steps:

1. Calculate the vertical offset of the desired element relative to its parent div:

<code class="javascript">var myElement = document.getElementById('element_within_div');
var topPos = myElement.offsetTop;</code>

2. Utilize scrollTop to scroll the div to the specified position:

<code class="javascript">document.getElementById('scrolling_div').scrollTop = topPos;</code>

Alternatively, for a prototype JS implementation:

<code class="javascript">var posArray = $('element_within_div').positionedOffset();
$('scrolling_div').scrollTop = posArray[1];</code>

This approach ensures that the div scrolls to display the desired element at the top or as far down as possible if it's not visible by default.
