In that case, you need to combine multiple formfields into one cookie. A
cookie can handle a large amount of data, 4 KB is enough for pretty
large text fields. It is the maximum of 20 that is a pain in the ass.
Try this to set your cookies.
USAGE for Storage:
var tmp = new superCookie('cookiename');
tmp.add('subcookiename','value');
And for retrieval:
var tmp = new superCookie('cookiename');
tmp.load();
var value = tmp.get('subcookiename');
var cookie = document.cookie;
function getcookie(name) { // use: getCookie("name");
var index = cookie.indexOf(name + "=");
if(index == -1){
return '';
}
index = cookie.indexOf("=", index) + 1;
var endstr = cookie.indexOf(";", index);
if (endstr == -1){
endstr = cookie.length;
}
return unescape(cookie.substring(index, endstr));
}
function setcookie(name,value) {
if(document.cookie != document.cookie){
index = document.cookie.indexOf(name);
}else{
index = -1;
}
if(index == -1){
document.cookie = name + '=' + escape(value) + ';
expires=Monday, 04-Apr-2010 05:00:00 GMT';
}
}
function superCookie(name){
this.name = name;
this.raw = [];
this.serialized;
this.deserialized = [];
}
superCookie.prototype = {
serialize:function(){
var i = this.raw.length;
var tmp = [];
while(i--){
tmp.push('{name:\''+this.raw[i].label+'\',value:\''+this.raw[i].data+'\'
}');
}
this.serialized = tmp.join();
return this.serialized;
},
deserialize:function(){
if(!this.serialized){
return;
}
var self = this;
this.serialized.replace(/\{[^}]+\}/g,
function(match){self.deserialized.push(match)})
return this.deserialized;
},
add:function(name,value){
if(value.length <= 0){
value = 'null';
}
this.raw.push({label:name,data:escape(value)})
},
get:function(name){
var set = this.deserialize();
if(typeof set == 'undefined'){
return '';
}
var i = set.length;
while(i--){
eval('var tmp = ' + set[i] + ';');
if(tmp.name == name){
var value = unescape(tmp.value);
if(value != null && value != 'null'){
return value;
}else{
return '';
}
break;
}
}
return '';
},
toRaw:function(){
var set = this.deserialize();
if(typeof set == 'undefined'){
return;
}
var i = set.length;
this.raw = [];
while(i--){
eval('var tmp = ' + set[i] + ';');
this.raw.push({label:tmp.name,data:escape(tmp.value)})
}
},
load:function(){
this.serialized = getcookie(this.name);
this.toRaw();
},
save:function(){
setcookie(this.name,this.serialize());
}
}

This would be an interesting point to pursue - when submitting the form
you
set a cookie for EVERY form field - may be better off saving it in a
session
variable??
Live headers / Page info via Netscape / Mozilla etc are very useful when
looking at things like this.
