Incorporating JavaScript and Alpine.js to Monitor and Log Changes in Input Range Values

I have developed a basic app that logs the input range value to the console when the range input changes. Interestingly, it works flawlessly when I slide the slider left and right with my cursor. However, when I programmatically change the value using JavaScript, the slider's value updates but the console.log function does not trigger, resulting in no log appearing in the console.

// Changing input range value using JavaScript
const slider = document.getElementById('slider')
slider.value=4 // The position of the input range button has moved
// When manually changing the value with the mouse cursor, the console.log successfully logs the data value
// However, when doing it programmatically with JavaScript, it fails to log the data
<div x-data="{data: 3}">
  <input type="range" id="slider" name="slider" min="1" max="5" x-model="data" @change="console.log(data)">
</div>

Answer №1

Modifying values through code does not automatically trigger an update. However, by dispatching an event, the changes can be captured:

// Ensure bubbles is set to true for bubbling up in the DOM
// Ensure cancelable is set to true so that the event can be stopped (preventDefault)
let customEvent = new Event('change', {bubbles: true, cancelable: true});
slider.dispatchEvent(customEvent);
