Benefits of taking our course
Functional Tools
1 - CodeIgniter Framework: CodeIgniter is a powerful PHP framework that facilitates rapid application development. It provides a structured and well defined approach to building web applications by adhering to the Model View Controller (MVC) architecture. CodeIgniter is lightweight, making it easier for developers to create high performance applications. In this training program, students will explore how to leverage CodeIgniter's built in functionalities to implement AJAX features efficiently, particularly in handling textbox events.
2) JavaScript: JavaScript is the backbone of interactive web applications, enabling dynamic content updates without requiring complete page reloads. Students will gain a solid understanding of how to use JavaScript to respond to events such as ‘change’ or ‘blur’ on textboxes. The training will cover essential techniques for manipulating the Document Object Model (DOM), allowing for real time updates and validations based on user input, thus enhancing user experience.
3) jQuery Library: jQuery simplifies JavaScript programming by offering a concise syntax for handling common tasks, such as AJAX requests and event handling. In this course, students will learn how to utilize jQuery to streamline their AJAX calls, making it easier to send and receive data asynchronously. They will work on examples demonstrating how to capture textbox events and perform efficient form submissions without full page reloads.
4) AJAX (Asynchronous JavaScript and XML): AJAX is a technique that allows web applications to send and receive data asynchronously from a server without interfering with the display and behavior of the existing page. The training program will introduce AJAX concepts thoroughly, focusing on how to implement AJAX functionality in conjunction with CodeIgniter. Students will learn how to handle requests and responses effectively, enabling seamless interaction with server side scripts based on users' actions.
5) XAMPP/WAMP Server: To set up a local development environment, the course utilizes XAMPP or WAMP, which are software stacks that provide Apache, MySQL, and PHP. Students will learn to configure and use these tools to host their CodeIgniter applications locally. Setting up a local server is crucial for testing and debugging AJAX functionalities in a controlled environment before deploying applications to production.
6) Browser Developer Tools: Understanding how to use browser developer tools is essential for any web developer. The training will cover how to use these tools to inspect network requests, monitor JavaScript execution, and debug AJAX related issues. Participants will become proficient in examining the request and response cycle, enabling them to troubleshoot potential problems effectively and optimize their applications for better performance.
7) Bootstrap Framework: While not directly related to AJAX, the Bootstrap framework will be discussed in the context of creating visually appealing and responsive front end interfaces. Students will learn to integrate Bootstrap into their applications to enhance user experience. They will explore how to style their textboxes and integrate AJAX functionality smoothly, ensuring that the interaction is as intuitive and user friendly as possible.
8) POST and GET Methods: A significant part of AJAX involves understanding how data is transmitted between the client and server. The course will cover the differences and usage of POST and GET methods in AJAX requests. Students will practice creating calls that send data from textboxes to the server, demonstrating the importance of choosing the right method based on specific use cases.
By engaging with these tools and technologies, students will be equipped with the necessary skills to create responsive and user friendly web applications using AJAX within the CodeIgniter framework. This comprehensive training ensures that they are ready to tackle real world projects and challenges in the ever evolving landscape of web development.
