    help please..how to unescape() the value of a cookie?

    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="JavaS cript">
    var arrRecords = new Array();
    var arrCookie = new Array();
    var recCount = 0;
    var strRecord="";
    expireDate = new Date;
    expireDate.setD ate(expireDate. getDate()+365);

    function cookieVal(cooki eName) {
    thisCookie = document.cookie .split("; ")
    for (i = 0; i < thisCookie.leng th; i++) {
    if (cookieName == thisCookie[i].split("=")[0]) {
    return thisCookie[i].split("=")[1];
    }
    }
    return 0;
    }

    function loadCookie() {
    if(document.coo kie != "") {
    if(cookieVal("R ecords") != ""){
    arrRecords = cookieVal("Reco rds").split("," );
    }
    currentRecord() ;
    }
    }

    function setRec() {
    strRecord = "";
    for(i = 0; i < document.frm1.e lements.length; i++) {
    strRecord = strRecord + document.frm1.e lements[i].value + ":";
    }
    arrRecords[recCount] = strRecord;
    document.frm2.a dd.value = " NEW ";
    document.cookie = "Records="+arrR ecords+";expire s=" +
    expireDate.toGM TString();
    }


    function newRec() {
    switch (document.frm2. add.value) {
    case " NEW " :
    varTemp = recCount;
    for(i = 0; i < document.frm1.e lements.length; i++) {
    document.frm1.e lements[i].value = ""
    }
    recCount = arrRecords.leng th;
    document.frm2.a dd.value = "CANCEL";
    break;
    case "CANCEL" :
    recCount = varTemp;
    document.frm2.a dd.value = " NEW ";
    currentRecord() ;
    break;
    }
    }

    function countRecords() {
    document.frm2.a ctual.value = "Record " + (recCount+1)+";
    "+arrRecords.le ngth+" saved records";
    }

    function delRec() {
    arrRecords.spli ce(recCount,1);
    navigate("previ ous");
    setRec();
    }

    function currentRecord() {
    if (arrRecords.len gth != "") {
    strRecord = arrRecords[recCount];
    currRecord = strRecord.split (":");
    for(i = 0; i < document.frm1.e lements.length; i++) {
    document.frm1.e lements[i].value = currRecord[i];
    }
    }
    }

    function navigate(contro l) {
    switch (control) {
    case "first" :
    recCount = 0;
    currentRecord() ;
    document.frm2.a dd.value = " NEW ";
    break;
    case "last" :
    recCount = arrRecords.leng th - 1;
    currentRecord() ;
    document.frm2.a dd.value = " NEW ";
    break;
    case "next" :
    if (recCount < arrRecords.leng th - 1) {
    recCount = recCount + 1;
    currentRecord() ;
    document.frm2.a dd.value = " NEW ";
    }
    break;
    case "previous" :
    if (recCount > 0) {
    recCount = recCount - 1;
    currentRecord() ;
    }
    document.frm2.a dd.value = " NEW ";
    break;
    default:
    }
    }

    function pageLoad(){

    else return [];
    }
    if (arguments.leng th < 2) cnt = this.length-ind;
    cnt = (typeof cnt == "number") ? Math.max(0,cnt) : 0;
    removeArray = this.slice(ind, ind+cnt);
    endArray = this.slice(ind+ cnt);
    this.length = ind;
    for (var i = 2; i < arguments.lengt h; i++) {
    this[this.length] = arguments[i];
    }
    for(var i = 0; i < endArray.length ; i++) {
    this[this.length] = endArray[i];
    }
    return removeArray;
    }
    Array.prototype .splice = array_splice;
    }
    recCount = 0;
    loadCookie();
    countRecords();

    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.e lements.length; i++) {
    strRecord = strRecord + document.frm1.e lements[i].value + ":";
    }
    arrRecords[recCount] = strRecord;
    document.frm2.a dd.value = " NEW ";
    document.cookie = "Records="+esca pe(arrRecords)+ ";expires=" +
    expireDate.toGM TString();
    }



    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!

    Koen

      JRS: In article <OAmNa.6395$7h. 12140@afrodite. telenet-ops.be>, seen in
      news:comp.lang. javascript, koen colen <koen.colen@pan dora.be> posted at

      [color=blue]
      >expireDate = new Date;
      >expireDate.set Date(expireDate .getDate()+365) ;[/color]

      That expires a day early 25% of the time.

      expireDate.setM onth(expireDate .getMonth()+12) ;

      That, at a cost of one more character, gives the right date without any
      getYear/getFullYear concern.
