Stop the event bubbling, click the child does not respond to the parent element

Stop event bubbling;

Who would not want to put anyone inside the bubble

can use

return false; 

may also be used

the stopPropagation (); 
need to pass a parameter such as:

$ ( "Son.") the Click (function (E) {. 
  Alert ( "Son hello"); 
    e.stopPropagation (); 
}); 

but when I do start point home, use return false does not work; 
stopPropagation ( ); can be achieved; 
I do not know how it happened;
