Hi B,
I would think this is an important feature so the fact that you are
looking to do the same thing means I am not alone.. I'd like to
submit this as a feature but am still trying to figure out the state
of trigger's undocumented parameter "fn":
http://groups.google.com/group/jquery-en/browse_thread/thread/ace02e1b78894fc2/1be5003cc4cd690c#1be5003cc4cd690c
The change is trivial but you have to change both the public trigger
function and the helper function (you'll find two trigger functions in
the jquery source).. Because I don't know where the undocumented fn
param is used, I put my new eventsParam after that:
/* helper trigger function */
trigger: function(type, data, elem, donative, extra, eventParams) {
// Clone the incoming data, if any
data = jQuery.makeArray(data || []);
// Handle a global trigger
if ( !elem ) {
// Only trigger if we've ever bound an event for it
if ( this.global[type] )
jQuery("*").add([window,
document]).trigger(type, data);
// Handle triggering a single element
} else {
// don't do events on text and comment nodes
if ( elem.nodeType == 3 || elem.nodeType == 8 )
return undefined;
var val, ret, fn = jQuery.isFunction( elem[ type ] ||
null ),
// Check to see if we need to provide a fake
event, or not
event = !data[0] || !data[0].preventDefault;
// Pass along a fake event
if ( event ){
if(eventParams!=null){
eventParams.type = type;
eventParams.target= elem;
data.unshift( this.fix(eventParams) );
}
else
data.unshift( this.fix({ type: type,
target: elem }) );
}
// Enforce the right trigger type
data[0].type = type;
// Trigger the event
if ( jQuery.isFunction( jQuery.data(elem, "handle") ) )
val = jQuery.data(elem, "handle").apply( elem,
data );
// Handle triggering native .onfoo handlers
if ( !fn && elem["on"+type] && elem["on"+type].apply(
elem, data )
=== false )
val = false;
// Extra functions don't get the custom event object
if ( event )
data.shift();
// Handle triggering of extra function
if ( extra && jQuery.isFunction( extra ) ) {
// call the extra function and tack the current
return value on
the end for possible inspection
ret = extra.apply( elem, val == null ? data :
data.concat( val ) );
// if anything is returned, give it precedence
and have it
overwrite the previous value
if (ret !== undefined)
val = ret;
}
// Trigger the native events (except for clicks on
links)
if ( fn && donative !== false && val !== false && !
(jQuery.nodeName(elem, 'a') && type == "click") ) {
this.triggered = true;
try {
elem[ type ]();
// prevent IE from throwing an error for some
hidden elements
} catch (e) {}
}
this.triggered = false;
}
return val;
},
/* public trigger function*/
trigger: function( type, data, fn ,eventParams) {
return this.each(function(){
jQuery.event.trigger( type, data, this, true,
fn,eventParams );
});
},
