th:field is directly related to th:object. Somewhere in your code you are defining a th:object like this (probably in a form tag).

th:field

th:object

th:object

<form th:object="${whatever} />


A th:field expression is equivalent in this way:

*{numEventsByPage} == ${whatever.numEventsByPage}


Notice that whatever must match your th:object definition. You can also use the #object shortcut to refer to your th:object. So your options are:

whatever

th:object

#object

th:object

<!-- Where whatever is your th:object -->
<div th:if= "${whatever.numEventsByPage != null}">


or

<div th:if= "${#object.numEventsByPage != null}">


1.) Currently as per the code you Pasted here, it is being restricted to this input here only.
And Yes! you can use it Globally however By 'using it Globally' I'm assuming that you want to put this object inside a JavaScript Global Variable. if that's the case use -

Thymeleaf's <script th:inline="javascript"> tag.'
Also, alternatively in order to get this value ,you can always use JQuery or JavaScript.

<script th:inline="javascript">

2.)To answer this question, try this :---

<div th:if="${numEventsByPage != ''}" >
