Article Introduction：Core points Event delegates in jQuery are a technique for attaching a single event handler to a parent element instead of multiple handlers attached to individual elements, thereby reducing memory usage and improving performance. The jQuery function on() can be used to implement event delegate, and the optional second parameter specifies the selector for the delegate event handler. Then use the event.target property to identify which element triggered the event. In dynamic applications, elements are often added or removed, and event delegates are especially useful because it eliminates the need to manually manage events and reduces code complexity. However, it should be noted that the sub-event handler handles before delegating the event handler and may prevent the event from propagating. jQuery simplification
