Can not add external javascript with data-complete attributes in controller and smarty template

[Jahangir]

I am developing a custom payment module in PrestaShop 1.6 my front controller path is: mymodule/controllers/front/payment.php

payment.php contains:

$this->context->smarty->assign(array( 
'dataCompleteURL' =>  Tools::getShopDomainSsl(true, true) . __PS_BASE_URI__.'index.php?fc=module&module=mymodule&controller=callback&cart='.$cartID));
$this->setTemplate('payment.tpl');

my template file path is: mymodule/views/templates/front/payment.tpl

payment.tpl contains:

<script src="http://easternbank.test.gateway.com/checkout.js" data-complete="{$dataCompleteURL}" type="text/javascript"> </script>

The problem is In my localhost it is working fine. I get data-complete URL in script tag. But when I install the module in my test server I do not get the data-complete URL.

 

I have found that the problem is "https" in "src" of script tag. I can not understand why data-complete vanishes if the src URL begins with https. without https it is okay

when I view the source from browser for the following code with https in src:

<script src="http://easternbank.test.gateway.com/checkout.js" data-complete="{$dataCompleteURL}" type="text/javascript"> </script> 

data-complete attribute vanishes. But when I view source for the script with src without "https" I get the data-complete attribute.

I could not find the reason.

 

I can add javascript in controller payment.php using :

$this->context->controller->addJS(($this->_path).'js/checkout.js'); 

But do not know how to pass data attributes in addJS function.

 

Any help or suggestion will be appreciated. Thanks in advance.
