IS it possible to append onclick javascript funtion in HTML source code?

Hi Community,

IS it possible to append onclick javascript funtion in HTML source code?

I am trying to append below code to my HTML source code field in knowledge base. But when i update it, it just strips it off. Is it not supported. Any suggestions to fix it>?

Trying to insert this code:

<div class=""SH_Toggle"" onclick=""document.getElementById('Brain_TR').classList.toggle('highlight_row');document.getElementById('Brain_Details_TR').classList.toggle('hide');document.getElementById('Brain_Details_TR').classList.toggle('active_details_row');"">
(More Information: <span style=""color:blue;"">Show/Hide&nbsp;⇵</span>)</div>

However when i update the page, it just strips it off to this code:

<div class=""SH_Toggle"">(More Information: <span style=""color: blue;"">Show/Hide&nbsp;⇵</span>)</div>
</div>

Any help on this would be appreciated..

Thanks.
