Clojure Toggle Button
To create a toggle button in Clojure, you can use the reagent
library, which is a ClojureScript wrapper for React. Here's an example of how you can create a toggle button using reagent
:
(ns my-app.core
(:require [reagent.core :as reagent]))
(defn toggle-button []
(let [toggle-state (reagent/atom false)]
(fn []
[:div
[:button {:on-click #(swap! toggle-state not)}
(if @toggle-state
"ON"
"OFF")]])))
(reagent/render [toggle-button] (.getElementById js/document "app"))
In this example, we define a toggle-button
function that returns a Reagent component. The component uses an atom, toggle-state
, to keep track of the button's state. When the button is clicked, the toggle-state
atom is updated using the swap!
function to toggle its value. The button's text is determined based on the value of toggle-state
.
To render the toggle button, we use the reagent/render
function and pass in the toggle-button
component. The rendered component is then attached to the element with the ID "app" in the HTML document.
Please note that this is just a basic example, and you can customize the toggle button further based on your specific requirements.
