Hello!

I have a form on my page that forces a file to be downloaded after
submit When this happens my iframe goes white. is applied a css display: hidden in html.

Why does this happen?

Can you please provide your whole setup/shortcode.
because the plugin does depending on the config hide the iframe until all changes and then enabled again. But maybe you use the wrong attribute here.

Best, Michael

Also this can be a iframe protection. like "if in iframe we hide". This is a quite common way to prevent iframing.
But a document is downloaded - right?

Best, Michael

my shortcode:
[advanced_iframe securitykey="xxxxxxxxxxxxxxxxxxxxxxxxxxxxx" src="{{url-servicos}}/Publica/C" id="iframeServicos" width="100%" onload_resize="true" hide_page_until_loaded_external = "false"]


in my page content:
<script>
var iframe_id = "iframeServicos";
var iframe_content_id = "#iframeServicos";
var updateIframeHeight = "true";
var hide_page_until_loaded_external = "true";
</script>
<script src="https://www.tce.es.gov.br/wp-content/plugins/advanced-iframe/js/ai_external.js"> </script>

yes, the file is downloaded, but then applied visibility: hidden in the contents of the iframe

"/Publica/CertidaoRegularidadeTransferenciaVoluntaria/EmitirCertidaoRegularidadeTransferenciaVoluntaria"
does contain the correct settings.

hide_page_until_loaded_external = "false" needs to be true. Because if you set
var hide_page_until_loaded_external = "true"; in the remote page then it needs to be shown again on the remote page.

onload_resize="true" is for the same domain. Please remove it. also it seems you have some settings in the administration for resize on element resize. Please add:

use_shortcode_attributes_only="true" hide_page_until_loaded_external="true"

currently you have quite some errors in the Javscript console. They should be gone with the settings above.

var iframe_content_id = "#iframeServicos";
is also not not needed - it only works together with
var iframe_content_styles

As you don't change the css you can acutally remove the
hide_page_until_loaded_external from the remove Js settings and also from the shortcode.

Always start simple..

Best, Michael

my problem is with ai_external.js, I'm falling in some case below:

ai_external.js
if (document.documentElement && write_css_directly == 'false') {
document.documentElement.style.visibility = 'hidden';
}

In my content, after my download starts, the page (iframe content) is reloaded.

so please remove

var iframe_content_id = "#iframeServicos";

because then you do not get to this code.

But normally I remove this again in line 281.
I just debugged and you reload does not trigger a onload event. Maybe because of the download you start in parallel. I found a few bug reports for chrome that this can be an issue.

In your case remove iframe_content_id and you should be fine.

Best, Michael

Thank you for your help. It worked
I was afraid my automatic height would stop working.

I'm actually seeing multiple tabs on my console, but everything is working.

What do I do ? or do not I?

Thank you!

tabs on your console? I don't understand...

I do not know how to explain.
I'm going to improve my English.

It's all okay now, thank you.
