Uncaught ReferenceError using external script & jQuery Mobile

问题

I'm trying to create a web app but can't get my javascript to work.

When loading the page with a fresh started browser I get 'Uncaught ReferenceError: getResult is not defined' (is located in js/ajax.js) but when I refresh the page everything works. I have tried to move where the script loading takes place but I can't get it to work.

I found a bunch of similar questions but they seem to suggest to load script inside and to not use $(document).ready() and I am doing that already. Anyone?

EDIT: I noticed that the error only occurs when going from another jQuery mobile page.

;TLDR: <head> is ignored on internal pages when using jQuery Mobile.

To use jQuery Mobile with external styles and scripts, you're going to have to load the same set of scripts and styles to every page, per the documentation.
