Hi,

Is it possible to "inject" JavaScript code to the HTML "head" section of the first and last page of a survey? Something like this:

<head>
// other code
// my JS snippet here
</head>

There is a need to track user engagement via Google Analytics and Facebook Pixel and typically with these tools you have to add a JavaScript snippet just before the closing "head" tag of your HTML.

Many thanks.

You may either edit the Questionnaire Layout (for all pages in the questionnaire) or use pageHead() for single pages.

However, please note, that GDPR demands explicit agreement by the respondends before you are allowed to use tools like Giigle Analytics. Otherwise you risk severe punishment.

I need to add something in the head section of the *last page* only. How do I do that given that PHP cannot be used on the last page?

On the last page it won't be possible that easily, sorry. You can, however, place all necessary JavaScript at the top of the content. That is no problem with JS.

Another option is to introduce another (new) page before the last page and use buttonHide() there. This will then work very similary to the last page.
