Delegate in jQuery _ jquery

This article mainly introduces several small pitfalls encountered when using delegate in jQuery. I am used to using bind, live, and cannot be changed at the moment, record it and recommend it to you. I am used to bind and live, so I am not used to delegate...

You can bind events to dynamically generated tag elements. Maybe live and delegate are supported. However, live is not supported in the new version, and only delegate is supported.

Delegate is really special. It is different from the Binding style of other events.

This is because we get used to the previous bind style.

To put it simply, it is the general idea.

The delegate () method adds one or more event handlers to the specified element (a child element of the selected element) and specifies the function to run when these events occur.

The event handler using the delegate () method applies to current or future elements (such as new elements created by scripts ).

Syntax

$(selector).delegate(childSelector,event,data,function)

Parameters	Description
ChildSelector	Required. Specifies one or more child elements of the event handler to be appended.
Event	Required. Specifies one or more events to be appended to an element. Multiple event values are separated by spaces. Must be a valid event.
Data	Optional. Specifies additional data to be passed to the function.
Function	Required. Specifies the function that runs when an event occurs.

For example, this small code.
