Topic: Estensione Safari: cosa fa il codice?

[LolloMazzy]

Ho questo componente aggiuntivo col nome di IPFuck. Mi potete aiutare a studiare il suo codice?

Codice: [Seleziona]

var ipfuck = {

inited: false,

init: function() {
if (!this.inited) {
if (this.get_pref('ipfuck_enabled') == true)
this.register();

this.inited = true;
}
},

observe: function(subject, topic, data) {

if (topic == "http-on-modify-request") {

var channel = subject.QueryInterface(Components.interfaces.nsIChannel);

if (!this.in_array(channel.originalURI.asciiHost, this.get_pref('white_list').split(','))) {
var httpChannel = subject.QueryInterface(Components.interfaces.nsIHttpChannel);

var ip = this.get_ip();

if (this.get_pref('synchronize')) {
var ip2 = ip;
var ip3 = ip;
} else {
var ip2 = this.get_ip();
var ip3 = this.get_ip();
}

if (this.get_pref('xforwarded'))
httpChannel.setRequestHeader("X-FORWARDED-FOR", ip, false);

if (this.get_pref('via'))
httpChannel.setRequestHeader("VIA", ip2, false);

if (this.get_pref('clientip'))
httpChannel.setRequestHeader("CLIENT-IP", ip3, false);
}
}
},

get observerService() {
return Components.classes["@mozilla.org/observer-service;1"].getService(Components.interfaces.nsIObserverService);
},

register: function() {
this.set_pref('ipfuck_enabled', true);
document.getElementById('ipfuck-toolbar-button').className = 'toolbarpanel-menu-iconic ipfuck_enabled';

return ip;
}
},

in_array:function(needle, haystack) {
for (var i = 0; i < haystack.length; i++) {

return true;
}
return false;

        .getService(Components.interfaces.nsIPrefService);

document.persist("nav-bar", "currentset");
}

window.addEventListener("load", ipfuck.addbutton, false);

Cosa c'entra Safari con un forum sul software Mozilla? Se effettivamente è un'estensione per Safari, non c'entra nulla con questo forum e devo chiudere.

Avendo già chiuso una discussione in Altro, ho l'impressione che tu abbia bisogno di un forum in cui si discute esclusivamente di programmazione. E questo non è il forum adatto.
