javascript

Due to page performance you should load javascript at the end of page (see http://developer.yahoo.com/performance/rules.html), at least all javascript you can defer to load. There are script that have to load at the very begin of page. But are you sure there is no option?

Well, actually this is a critical reflection on my own script. When I wrote imagedata drupal example module I replaced to {'imagedata ...} a direct call to jquery plugin.

There are a lot of situation where javascript function is called

Ok, I admit I do not search to much out there if this is available..

A simple jquery plugin that permit to show context menu

I take inspiration from yahoo library: here is an example

But I want it as jquery plugin and also I want to have option to choose the way it should work, for example I also want to fire context menu on hold down left mouse button for 1 second, or just hover on element.

I lost some time to debug this

$("#link").click(function(){
   $("#target").load('url/to/load');
});

The problem is on Internet Explorer (all version) that refuse to load data in #target, using $.get and innerHTML(data) do not help. The problem is with no well formed html! Internet Explorer refuse to load in dom a malformed html.
Thus

$("#link").click(function(){
   $("#target").load('url/to/load');
   window.open('url/to/load');
});

This is a simple jQuery plugin for purpose of loading phase of an ajax request or anything else.

$("#testdiv").waiting({imgsrc:"/files/aj-blue.gif"});

to stop a waiting div

$("#testdiv").stopWaiting();

I look for this everywhere: how to move multiple option inside a select

function upfield() {
  var el = $('#selectedfield').children('[@selected]:first').prev();
  $("#selectedfield")
    .children('[@selected]')
    .each(function(){
	$(this).insertBefore(el);
      });

}

function downfield() {
  var el = $('#selectedfield').children('[@selected]:last').next();
  $("#selectedfield")
    .children('[@selected]')
    .each(function(){
	$(this).insertAfter(el);
	el = $(el).next();
      });
}

XMLHttpRequest use, works only if url is on same site. checklogin.php give <KO/> if login è fails <OK>XXX</OK> with XXX id of user when login è is ok
