Course Introduction：This tutorial aims to solve the problem that the new load element event binding fails when dynamic content loading is used with jQuery AJAX and PHP. The core is to understand and apply the event delegation mechanism of jQuery. By binding the event listener to a static parent element, it effectively handles the dynamically generated DOM elements in the AJAX response, ensuring that functions such as "Load More" can still work normally after multiple clicks, avoiding repeated binding and event loss.

Course Introduction：This document is intended to solve how to generate an array containing all checkbox statuses (checked and unchecked) when PHP handles checkboxes. By modifying the naming of check boxes in HTML forms and combining PHP's $_POST method, you can ensure that the array contains the key-value pairs of each check box, where "1" means selected and "0" means unselected. Solve the problem that the check box array only contains selected items, ensure data integrity and facilitate subsequent processing.

Course Introduction：This article aims to solve the problem of getting specific rows of data by clicking a button and sending it to the server using jQuery's AJAX method in a dynamically generated HTML table. The point is how to correctly locate the row that triggers the event and extract the required data from it. At the same time, the importance of using unique IDs in HTML documents is emphasized, and a solution to using class instead of IDs is proposed.

Course Introduction：PHP handles type prompts and return types by allowing developers to explicitly declare the expected data types of function parameters and return values. Specific methods include: 1. Type prompt is used to ensure that the function or method receives the correct type of parameters, otherwise TypeError will be raised; 2. Return type declaration specifies the value type that the function should return, prevent errors and clarify expectations; 3. Supported types include scalar types (string, int, float, bool), arrays, callable types, class names, union types (PHP8.0) and intersection types (PHP8.1); 4. If you return a value that may be null, you need to use a nullable type such as?string; 5. Enable declare(strict_types

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
