Check If Jquery Ui Is Loaded Duplicate

When you're working on a web project that involves jQuery UI, it's essential to ensure that the library is loaded properly to avoid any issues with duplicate loading. Detecting whether jQuery UI is already loaded can save you time and prevent potential conflicts in your code.

One simple way to check if jQuery UI is loaded is by leveraging the `$.ui` namespace it creates when successfully loaded. By checking the presence of this namespace, you can determine if jQuery UI is already available on the page. Here's how you can do it:

if (typeof $.ui !== 'undefined') {
    // jQuery UI is already loaded
    console.log('jQuery UI is loaded');
} else {
    // jQuery UI is not loaded
    console.log('jQuery UI is not loaded');
    // You can load jQuery UI here if needed
}

In the code snippet above, we use a conditional statement to check if `$.ui` is defined. If it's defined, it means jQuery UI is loaded, and we log a message confirming that. If it's not defined, it indicates that jQuery UI is not loaded, and you can take appropriate actions, such as loading the library.

Another approach is to check if a specific jQuery UI component is available. This can be useful if you want to verify the presence of a particular module within jQuery UI. For example, you can check for the existence of the `draggable` module as follows:

if ($.ui && $.ui.draggable) {
    // Draggable module is available
    console.log('Draggable is loaded');
} else {
    // Draggable module is not available
    console.log('Draggable is not loaded');
    // Load the draggable module if needed
}

By checking for a specific component like `draggable`, you can have more granular control over the detection process and tailor your actions accordingly.

Additionally, if you are using jQuery UI in a modular fashion, it's a good practice to check each component individually to avoid unnecessary duplication and to ensure that only the required modules are loaded.

Remember, detecting if jQuery UI is loaded duplicate is crucial for maintaining a well-organized and efficient codebase. By following these simple techniques, you can easily determine the status of jQuery UI on your page and take the necessary steps to handle the loading process effectively.

Stay vigilant, keep your code tidy, and enjoy a seamless development experience with jQuery UI!
