hx-include attribute allows you to include additional element values in an AJAX request. The value of
this attribute is a CSS query selector of the element or elements to include in the query.
Here is an example that includes a separate input value:
<div> <button hx-post="/register" hx-include="[name='email']"> Register! </button> Enter email: <input name="email" type="email"/> </div>
This is a little contrived as you would typically enclose both of these elements in a
form and submit
the value automatically, but it demonstrates the concept.
hx-includeis inherited and can be placed on a parent element
