jquery generated element registration event is invalid and event delegate usage

After the page is loaded, we use JS to generate HTML code to the page, dynamically add elements on the page

However, here may be a lot of people have to encounter a problem arises, when you dynamically added elements to the page, found that the binding event of this element is invalid, such as click on the point of no effect at all

The event delegate is used here to allow future elements to bind events

Method One

function (){
   ...............
});

This will ensure that the elements you generate in the future will also be able to bind the order-click event

Method Two

On seems to satisfy this method, but also to set the selector parameter of the On () method:

function (){    ..............});
