IFrame Resizer not resizing

Question

I'm working on this page here: http://factor1hosting.com/~dnaz/wordpress/certifications/

And I am trying to pull in a cross domain iframe.

I am using @DavidJBradshaw's iFrame Resizer to achieve this. However, I am not getting the iframe to work correctly.

I can use just the plain javascript init:

<script>iFrameResize({log:true})</script>

And when I use this I do get the log but it does not resize. I've also tried the jQuery method:

$('iframe').iFrameResize( [{log: true}] );

And don't get the log or the iframe resized. I also tried wrapping it in a document ready and that doesn't achieve it either.

Anyone have any thoughts or ideas as to why this isn't firing correctly? My console isn't throwing any JS errors... Thanks!

EDIT: here is an example of how I am currently setup on the HTML side.

<iframe src="http://phpstack-9420-21004-48731.cloudwaysapps.com/onlinecert/certification/login" width="100%" scrolling="no"></iframe>
                <script>
                    jQuery(document).ready(function () {
                        jQuery('iframe').iFrameResize( [{log:true}] );
                    });
                </script>

EDIT 2: Here is my console log when it does fire, and it's setting the iframe to 150px even though the content extends longer then that.

Answer 1

Got it!

The iframe body height wasn't calculating correctly, so I changed how it calculates what the iframe height should be. I am using 'lowestElement' to achieve this and it works great.

iFrameResize({
    log                     : true,                  // Enable console logging
    enablePublicMethods     : true,                  // Enable methods within iframe hosted page
    heightCalculationMethod : 'lowestElement',
});

From the GitHub repo: lowestElement Loops though every element in the the DOM and finds the lowest bottom point
