Hello group,
I hope you guys can help me out, I am modifying a piece of code from Joe
Norman,
I did found the code here:
http://www.intranet2internet.com/public/default.asp?PAGE=sscript&ID=3
My question:
How can I save the value's of a form to a cookie, but in the textarea's of
that form the "hard returns" must be saved with it?
I have this code:
<html><HEAD>
<SCRIPT LANGUAGE="JavaScript">
var arrRecords = new Array();
var arrCookie = new Array();
var recCount = 0;
var strRecord="";
expireDate = new Date;
expireDate.setDate(expireDate.getDate()+365);
function cookieVal(cookieName) {
thisCookie = document.cookie.split("; ")
for (i = 0; i < thisCookie.length; i++) {
if (cookieName == thisCookie.split("=")[0]) {
return thisCookie.split("=")[1];
}
}
return 0;
}
function loadCookie() {
if(document.cookie != "") {
if(cookieVal("Records") != ""){
arrRecords = cookieVal("Records").split(",");
}
currentRecord();
}
}
function setRec() {
strRecord = "";
for(i = 0; i < document.frm1.elements.length; i++) {
strRecord = strRecord + document.frm1.elements.value + ":";
}
arrRecords[recCount] = strRecord;
document.frm2.add.value = " NEW ";
document.cookie = "Records="+arrRecords+";expires=" +
expireDate.toGMTString();
}
function newRec() {
switch (document.frm2.add.value) {
case " NEW " :
varTemp = recCount;
for(i = 0; i < document.frm1.elements.length; i++) {
document.frm1.elements.value = ""
}
recCount = arrRecords.length;
document.frm2.add.value = "CANCEL";
break;
case "CANCEL" :
recCount = varTemp;
document.frm2.add.value = " NEW ";
currentRecord();
break;
}
}
function countRecords() {
document.frm2.actual.value = "Record " + (recCount+1)+";
"+arrRecords.length+" saved records";
}
function delRec() {
arrRecords.splice(recCount,1);
navigate("previous");
setRec();
}
function currentRecord() {
if (arrRecords.length != "") {
strRecord = arrRecords[recCount];
currRecord = strRecord.split(":");
for(i = 0; i < document.frm1.elements.length; i++) {
document.frm1.elements.value = currRecord;
}
}
}
function navigate(control) {
switch (control) {
case "first" :
recCount = 0;
currentRecord();
document.frm2.add.value = " NEW ";
break;
case "last" :
recCount = arrRecords.length - 1;
currentRecord();
document.frm2.add.value = " NEW ";
break;
case "next" :
if (recCount < arrRecords.length - 1) {
recCount = recCount + 1;
currentRecord();
document.frm2.add.value = " NEW ";
}
break;
case "previous" :
if (recCount > 0) {
recCount = recCount - 1;
currentRecord();
}
document.frm2.add.value = " NEW ";
break;
default:

I know, when you want to save "hard returns" in a cookie, you need to
escape() the value of a textarea when saving it, and here's how I've
modifided that in the code:
function setRec() {
strRecord = "";
for(i = 0; i < document.frm1.elements.length; i++) {
strRecord = strRecord + document.frm1.elements.value + ":";
}
arrRecords[recCount] = strRecord;
document.frm2.add.value = " NEW ";
document.cookie = "Records="+escape(arrRecords)+";expires=" +
expireDate.toGMTString();
}
Works fine but my big question is: where can I Unescape the value when
loading the cookie?
Hope anyone can help me out on this one,
Thanks for any insight!
