How to add a Go To Cart button on the product page

Yes, I wrote a blog post about how to make a pop-up appear when a user adds an item to their cart which gives them the option to continue shopping or proceed to their cart.

This script is great. However, when I load these three scripts I get text that pops up in the top left corner of the page on loading of my cover page. Is this typical behavior? It doesn't seem to do it on the "behind the scenes" site that I am still building. Is there any way to avoid this? See video attached --first 10 seconds only unless you want to watch me figure out where my QuickTime app went. 😃

Also attached is a screenshot of the header text. I have a feeling I have typo here trying to copy/paste several injections for various customizations and plugins.

@JonathanK In summary, it's expected behaviour for this piece of code but I can see why this would be a problem on a live site.

It's due to the way the sample of code has been written. Snippets provided free on forums are often written quickly to show the art of the possible, to help someone decide whether a solution might help them. Issues like this "flash of unstyled content" are to be expected. These snippets are simply not designed to be used in place of tested, paid solutions. They are "get you started" code that shows what is possible and allows you to (a) decide if Squarespace might be suitable and (b) consider whether it is worth hiring a developer to customise an element of your site.  

This particular snippet includes a section of HTML (lines 2 to 12) that creates the buttons. It is being added to the top of every page on the site, regardless of whether the page is a product page or has an 'Add to Cart' button on it. That's why you see it on your cover page, even though there's no need for the buttons on this page. If the developer had been paid to write this, they would have used JavaScript instead, checking for the Cart button first and, only when it is found, creating the buttons on the page. 

Pretty much what @paul2009 said, it’s meant more as a starting off point. As you can imagine when trying to provide a solution such as this, there are a lot of different variables in how a Squarespace website might be configured from AJAX to the specific templates, product blocks vs product pages... So one for all solutions like this do sometimes present problems. 

It was basically designed to work in a wide variety of use cases whilst also being simple enough for the lay person or anyone else who would like to develop on it further to decipher. In addition it was also designed in a way that makes it relatively easy to maintain incase something fundamentally changes on Squarespace. Unfortunately that means that in some instances it does cause some less then ideal situations like this one with the cover page. 

Really the only reason I suggest you put the html code in the global header is incase you have AJAX enabled. If you don’t then you can simply put it into the specific product page header which will solve your problem.
