Hi, that's what scriptaculous.js does:
it makes sure that prototype.js >= 1.5.0 is present then loads
builder.js, effects.js, dragdrop.js, controls.js, and slider.js (a total
of probably 150Kb of uncompressed javascript code)
what I propose instead is to load only what's needed by a given widget
and remove the scriptaculous.js script alltogether, since the
functionality of loading resources is implemented in NXThemesJsf
already, with the possibility to load all scripts at once (merged in one
single file) and in a gzip-compressed format when supported by the client.
so if you need drag-and-drop, simply require dragdrop.js in the widget
definition (interdependencies between the modules can be declared too to
simplify registrations) if you need effects.js require effects.js, etc..
any comment on this?
= scriptaculous.js ==================
var Scriptaculous = {
Version: '1.6.5',
require: function(libraryName) {
// inserting via DOM fails in Safari 2.0, so brute force approach
document.write('<script type="text/javascript"
src="'+libraryName+'"></script>');
},
load: function() {
if((typeof Prototype=='undefined') ||
(typeof Element == 'undefined') ||
(typeof Element.Methods=='undefined') ||
parseFloat(Prototype.Version.split(".")[0] + "." +
Prototype.Version.split(".")[1]) < 1.5)
throw("script.aculo.us requires the Prototype JavaScript
framework >= 1.5.0");
$A(document.getElementsByTagName("script")).findAll( function(s) {
return (s.src && s.src.match(/scriptaculous\.js(\?.*)?$/))
}).each( function(s) {
var path = s.src.replace(/scriptaculous\.js(\?.*)?$/,'');
var includes = s.src.match(/\?.*load=([a-z,]*)/);
(includes ? includes[1] :
'builder,effects,dragdrop,controls,slider').split(',').each(
function(include) { Scriptaculous.require(path+include+'.js') });
});
}
}
Scriptaculous.load();
