How the event bubbling problem raised after the on binding event in jquery solves _jquery

When on bind, I bind the element to document and bind the parent element to the ancestor element, which causes return false to prevent bubbling from being invalid.

<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">  

The on method binds events such as click on the Document object, and the click event on any element on the page bubbles to the Document object for processing.

Increased binding efficiency. When an event bubbles to the Document object, detecting the target of the event, if it matches the incoming selector (here is a button), triggers the event, otherwise it is not triggered.

Fixed to a uniform binding object, which is initially considered to be due to the binding mechanism of the on method.

So return false is not valid. After the child element and the parent element are modified to the same binding element, the problem is resolved

<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">  

The above is described in the small set of jquery in the binding event after the event bubbling problem and the solution, hope to help everyone!
