JS block default events and JS blocking events bubbling

E.stoppropagation (); Block event bubbling

Function: Stop event bubbling

function Stopbubble (e) {

if (e && e.stoppropagation) {

E.stoppropagation ();

} else {

Window.event.cancelBubble = true;

}

}

function Stopdefault (e) {

Block default browser action (web)

if (e && e.preventdefault) {

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

} else {
