Iframe SSI script II Linking

I try to engage the linking option of Iframe SSI script II.

In the description it says:

You can actually use links on your main page to load a page into your IFRAME (with the IFRAME automatically resized to that page's height of course). To do so, the link should look like this:

---

Code:

---

<a href="javascript:loadintoIframe('myframe', 'external.htm')">Link</a>

---

Now I'm in Joomla 3.6 and this link's not acceptable it seems.
What other style/format could I try?

Here's another option:

Code:

---

<a href="external.htm" onclick="loadintoIframe('myframe', this.href);return false;">Link</a>

Yes and thank you, Sir :-)
Awesome.
