    Lighthouse flags calls to document.write()

    How the heck do these get "fixed". From what I can gather they are coming from things like the Authorize.net's seal and the Trust logo for the secure certificate. Should these just be removed???

      Also Lighthouse - but what do you do when it's part of the script provided by places like Auth.net and the secure cert folks like Sectigo?

        Hi Leslie,

        If you cannot apply something like "async" to their script, then I would contact the vendor and see what can be done about it.

          I went to both websites to see if they have updated code - Comodo didn't. I haven't checked Auth.net. You would have hoped they would have been much more proactive.

            I'm working on something similar and am wondering if you could create an asynchronous loader script to bring in authorize and trustlogo:

            Code goes within script tags with async attribute.
            I can't post a script tag but the idea is that this script loads asynchronously which then creates the third party scripts.

            Code:
            function createScript(url, location, href, title, text) {
                var script = document.createElement('script');
                script.src = url;
                location.appendChild(script);
            
                var a = document.createElement('a');
                a.href = href;
                a.title = title;
                a.createTextNode = text;
                script.appendChild(a);
            }
            
            authorize = 'some_url'; // third-party script url
            trustlogo = 'some_url'; // third-party script url
            
            createScript(authorize, document.body, href, title, text);
            createScript(trustlogo, document.body, href, title, text);
            here is link to stackoverflow:

              never actually tried this, but had a similar thought that might be easier to pull off (if it works).

              Add the trust(etc) script into a readytheme content container, then wrap an AJAX (or mvt:call) call to the content container at the end of the document.

                Hey Bruce,

                I like your idea better. It's a lot less code and easier to maintain.
