回答1:

Let me explain you what is happening.

You have 2 separate HTML pages. Every page has a HEAD with javascript content.

Your problems comes to how jQuery Mobile handles page loading. Only first page is fully loaded. When next page is about to be loaded ONLY its body is loaded into the DOM and rest is discarded. This is because first page is already inside the DOM, there's no point in having to HEAD's inside.

This can be fixed in few ways:

Move your second page javascript to the HEAD of your first page
Move your second page javascript to the second page BODY
When making page transition add these attributes into your link: data-ajax="false" or rel="external". Just be waned, in this case transitions wont work so stick to solution 1. or 2.

Also take a look, I have another great answer regarding this + examples: Why I have to put all the script to index.html in jquery mobile
