Thanks for that Sam.
One further thing you might be able to help with. I have a function that
loops through some elements and then inside attaches a click even that
results in the HTML being reloaded... hence I need to call the function from
within itself.
My code looks like (I've put a note in where the call should be):
Thanks!
Tom
jQuery.fn.plotPins = function(gMap, gMarkerMan) {
//Reference to this jquery function.
var jElems = this;
return this.each(function(){
var listingID = jQuery(this).attr("id").replace(/pinned_/,"");
var lat = jQuery("abbr.lat", this).attr("title");
var lng = jQuery("abbr.lng", this).attr("title");
//Create the marker
var gPoint = new GLatLng(lat, lng);
var gMarker = new GMarker(gPoint, {icon: this._gIcon, draggable: true,
bouncy: true});
gMarkerMan.addMarker(gMarker, 1);
//pinnedListings[listingID] = gMarker;
//Attach the pull pin event.
jQuery("ul.pinned_action li.pinned_remove a",this).click(function(){
//Take the pin off the map.
gMap.removeOverlay(gMarker);
$("#pinned").load("ajax/GetPinned.ashx", {pull: listingID},
function(){
//I want to call the current function from itself here... my
attempt that doesn't work is:
//jQuery(jElems).plotPins(gMap, gMarkerMan);
});
//Do ajax here to pull the pin.
return false;
});
//Add the marker to the marker manager
//this._
});
};

This means that it would execute immediately and any variables
contained within the function won't be seen by other scripts.

Results in a saving of code. It is whatever you used in 1.

jQuery is the jQuery object and is passed on as the parameter (the $
at the start).
A (hopefully) simpler example:
(function(parameter1, parameter2) {
var space = " ";
alert(parameter1 + space + parameter2); // alerts 'hello world'
})("hello", "world");
alert(space); // space is not defined
It is one of the suggestions for authoring plugins:
