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：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.
