JS block default events and JS blocking events bubbling

Source: Internet
Author: User

E.stoppropagation (); Block event bubbling

Function: Stop event bubbling

function Stopbubble (e) {

If an event object is provided, this is a non-IE browser

if (e && e.stoppropagation) {

So it supports the Stoppropagation () method

E.stoppropagation ();

} else {

Otherwise, we need to use IE to cancel the event bubbling

Window.event.cancelBubble = true;



Features: Block event default behavior

function Stopdefault (e) {

Block default browser action (web)

if (e && e.preventdefault) {

E.preventdefault ()//prevents the occurrence of its default behavior and other

} else {

How to block the default action of a function in IE

Window.event.returnValue = false;


return false;
