Why Isn't My JSFiddle Code Working in My Local HTML Page?

JSFiddle Code Not Functioning in Local Webpage

The issue arises when attempting to integrate code that functions within JSFiddle into an HTML page. Despite incorporating the HTML, CSS, and JavaScript components, the JavaScript portion fails to execute.

Upon reviewing the code, it is evident that the HTML and CSS elements are implemented correctly. However, the JavaScript code is written within the

section of the HTML page. In this context, JavaScript execution occurs before the DOM elements (e.g., ) are initialized. Thus, the jQuery selector $('input[type="range"]') cannot locate the target elements, resulting in the JavaScript code's failure.

To rectify this, ensure that the JavaScript code is executed after the DOM elements have been parsed. This can be achieved by:

1. Wrapping the code within an onload handler:

window.onload = function() {
    // Your JavaScript code here
};

2. Utilizing jQuery's document ready handler:

$(document).ready(function() {
    // Your JavaScript code here
});

Alternatively, the JavaScript code can be placed at the end of the HTML page to ensure it executes after the elements it manipulates have been parsed.
