x-Frame options for older versions

I am working on an issue where I need to add x-frame options to the website in IIS.  This should be able to be done without any issues.  The issue is - I also need to add javascript to prevent click jacking for users that have older versions on the website I am working on.  Does that mean I need to add this javascript in the head tag on EVERY page in my website?  My website contains a lot of html pages, so not sure if there is an easier way to accomplish the fix compared to updating every page with some javascript for the older versions.
