This example actively searches a contacts database as the user enters text.
We start with a search input and an empty table:
<h3> Search Contacts <span class="htmx-indicator"> <img src="/img/bars.svg"/> Searching... </span> </h3> <input class="form-control" type="search" name="search" placeholder="Begin Typing To Search Users..." hx-post="/search" hx-trigger="keyup changed delay:500ms, search" hx-target="#search-results" hx-indicator=".htmx-indicator"> <table class="table"> <thead> <tr> <th>First Name</th> <th>Last Name</th> <th>Email</th> </tr> </thead> <tbody id="search-results"> </tbody> </table>
The input issues a
/search on the
keyup event and sets the body of the table to be the resulting content.
We add the
delay:500ms modifier to the trigger to delay sending the query until the user stops typing. Additionally,
we add the
changed modifier to the trigger to ensure we don’t send new queries when the user doesn’t change the
value of the input (e.g. they hit an arrow key).
Since we use a
search type input we will get an
x in the input field to clear the input.
To make this trigger a new
POST we have to specify another trigger. We specify another trigger by using a comma to
separate them. The
search trigger will be run when the field is cleared but it also makes it possible to override
the 500 ms delay on
keyup by just pressing enter.
Finally, we show an indicator when the search is in flight with the
