3. Basic HTMX Concepts – web development with HTMX
HTMX extends HTML with several powerful attributes that make it easy to add interactivity. Let’s explore some of the core concepts:
hx-get
The hx-get attribute triggers an AJAX GET request when an event occurs (e.g., a click).
<button hx-get="/example" hx-target="#result">Load Content</button>
<div id="result"></div>
hx-post
The hx-post attribute triggers an AJAX POST request.
<form hx-post="/submit" hx-target="#result">
<input type="text" name="data" required>
<button type="submit">Submit</button>
</form>
<div id="result"></div>
hx-target
The hx-target attribute specifies the element where the response will be rendered.
hx-trigger
The hx-trigger attribute defines the event that triggers the request.
<input hx-trigger="keyup changed delay:500ms" hx-get="/suggestions" hx-target="#suggestions">
<div id="suggestions"></div>
hx-swap
The hx-swap attribute determines how the response content is swapped into the target element.
<button hx-get="/example" hx-target="#result" hx-swap="outerHTML">Replace Content</button>
<div id="result">Original Content</div>
