- return falsefrom within a jQuery event handler is effectively the same as calling both- e.preventDefaultand- e.stopPropagationon the passed jQuery.Event object.
- e.preventDefault()will prevent the default event from occuring,- e.stopPropagation()will prevent the event from bubbling up and- return falsewill do both. Note that this behaviour differs from normal (non-jQuery) event handlers, in which, notably,- return falsedoes not stop the event from bubbling up.
