Specify HTMX select attribute using the URL fragment identifier.
I encourage reading the source hash-select.js since it contains only 4 significant lines of code.
Summarized, if an HTMX request path is given with a fragment identifier #some-id, then this extension will override hx-select with the selector #some-id.
Load the extension after loading HTMX:
<script src="https://unpkg.com/htmx-ext-hash-select"></script>Then,
<button hx-post="endpoint#status" hx-swap="outerHTML">Click for Status</button>Becomes approximately equivalent to
<button hx-post="endpoint#status" hx-select="#status" hx-swap="outerHTML">Click for Status</button>
