Event recurrence bindings and unbinding issues in jquery

In general, for this situation, our conventional approach is to first unbind, then bind, as follows:

$ (selector). Unbind (' click '). Bind (' click ', function () {...});

When this has a problem, unbind will unbind all of its previous click events and may affect other bindings, as there are two ways to resolve them:

The first type:

Use the event command space to uniquely identify the binding of this click, so that the event that the other click binds is not unbound when it is untied.

$ (selector). Unbind (' Click.selectorclick '). Bind (Click.selectorclick ', function () {});

The second type:

Do not use anonymous methods

var handler = function () {};

$ (selector). Unbind (' click ', Handler). bind (' click ', handler);
