Laravel Uncaught jQuery TypeError Autocomplete Is Not a Function

I am creating autocomplete search functionality with the help of jQuery UI in my PHP Laravel 11 application, we type something in Google and we get autosuggestions.

But when this application was not working properly, and I checkout on the console it showed some error uncaught type error autocomplete is not a function laravel

Checkout on console

When I did some research on jQuery (...).autocomplete is not a function Laravel error, then I noticed that my web page does not include the JS library from jQuery Ui's CSS and JS libraries.

Here's a step-by-step guide to troubleshoot and resolve this issue:

1. Check JavaScript dependencies

Ensure that all required JavaScript libraries for autocomplete functionality are properly included in your project. Common libraries for autocomplete functionality include jQuery UI, Select2, or other similar libraries.

2. Verify Script inclusion

Check that the JavaScript files containing the autocomplete functionality are correctly included in your HTML or Blade template files. They should be loaded before the code that attempts to use the autocomplete function.

3. Confirm DOM readiness

Make sure that your autocomplete initialization script is executed after the DOM is fully loaded. You can achieve this by wrapping your JavaScript code inside a $(document).ready() function if you're using jQuery.

Example

$(document).ready(function() { 
    // Autocomplete initialization code goes here 
});

4. Correct Function usage

Ensure that you are calling the autocomplete function correctly according to the documentation of the library you're using. Refer to the documentation of the specific autocomplete library you're utilizing to confirm the correct usage.

5. Check for conflicting Scripts

Look for any other JavaScript scripts that might be conflicting with the autocomplete functionality. Conflicts can occur when multiple scripts attempt to manipulate the same DOM elements or when there are conflicting variable names.

6. Debugging with Browser developer tools

Use your browser's developer tools (e.g., Chrome DevTools, Firefox Developer Tools) to debug JavaScript errors. Check the console for any error messages, including the exact line number and file where the error occurs. This can provide valuable insights into the cause of the issue.

7. Review Laravel Blade templates

If you're using Laravel Blade templates, ensure that you're properly passing required data to JavaScript variables within your Blade templates. Sometimes, incorrect data passing can lead to JavaScript errors.

8. Clear caches

Clear any caching mechanisms in your Laravel application, including browser caches and Laravel's internal caches. Stale JavaScript or cached assets could lead to unexpected behavior.
