Why Isn't My JSFiddle Code Working on My Own Website?

JSFiddle Code Not Working in Own Page: Troubleshooting JavaScript Execution

You've encountered an issue where code that functions perfectly in JSFiddle malfunctions when incorporated into your own web page. To resolve this perplexing problem, let's delve into the underlying causes.

The culprit lies in the placement of the JavaScript code. In JSFiddle, it's embedded in an onload handler, ensuring that it executes after the entire page has loaded. However, when you directly include the code in your HTML/JS and CSS files linked in the head, it executes prematurely.

At that point, the input elements haven't been parsed yet, causing $('input[type="range"]') to yield no results. To remedy this, your code needs to run after all page elements have been processed.

Solution: Onload Handler or Document Ready Handler

To achieve this, you can wrap your code in an onload handler:

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

Alternatively, use jQuery's document ready handler:

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

Or Include Script at End of Page

Another option is to include the script at the end of the page, which guarantees that it executes after all elements have been parsed.

Conclusion

By resolving this issue, you'll ensure that your JavaScript code behaves consistently in both JSFiddle and your own web page. Remember to consider the execution timing of your JavaScript code to avoid similar pitfalls in the future.
