javascript - Why jQuery trigger method doesn't use native events? -

-

jquery trigger works listeners attached jquery , won't work if listener attached otherwise (with prototype.js example).

but, @ same time - if trigger native event - works both jquery , other libraries.

the question - why jquery doesn't generate native event out of box , instead uses own stuff?

i'm curious , want know why works way.

p.s.

sample code native event

var trigger = function(el, eventname) {     if (document.createevent)     {         var evt = document.createevent('htmlevents');         evt.initevent(eventname, true, true);          return el.dispatchevent(evt);     }      if (el.fireevent)         return el.fireevent('on' + eventname); }

in versions of ie (before attachevent/addeventlistener), assign 1 handler/listener each event. jquery assign handler event, calls list of callbacks (the handlers assigned). allows consistent behaviour of multiple handlers across different browsers.
