Which tag would you primarily use to create AJAX-based input elements in Liferay?

The choice to primarily use the aui:input tag for creating AJAX-based input elements in Liferay is well-founded due to the advantages it offers when working with AUI (Alloy UI) components. The aui:input tag is specifically designed to integrate smoothly with AJAX functionality, making it easier for developers to create dynamic and responsive web applications.

Using aui:input, developers benefit from built-in features such as event handling and validation, which are essential for creating an interactive user experience. This tag supports various types of input, customizable for different use cases, while maintaining compatibility with AJAX calls to submit data without requiring a full-page refresh.

Although other tags like liferay-ui:input and liferay-ui:ajax may have their use cases, aui:input is specifically geared towards leveraging the capabilities of AUI, which is essential when building AJAX-based interfaces in Liferay. The focus of aui:input on AJAX integration and its comprehensive feature set makes it the most suitable choice for developers looking to implement AJAX-based input elements.
