    When you enter a page with a textbox. type in the textbox and then click the save button. When the same person enters the page again he will see what he have wrote!

    JavaScript is client-side only. Server-side code is required to save things that other visitors on a separate computer can see.

    JavaScript can only run in the browser. Code that runs on a server (ASP, JSP, PHP, Perl) is required if other visitors on a separate computer need to see the same information.

    I thought it read that "another" person enters the page.

    OK, so... JavaScript cannot save anything on the person's harddrive except a cookie.
    JavaScript also cannot save anything on the server.
    Do you want cookie code?

    he needs something to create a cookie to store information from that textbox, then something to read that information stored in that cookie, if you were to do it server side it would be a head ache, I don't think he wants other people to see what information another person has saved... I know how do some of what he is trying to do, but your the expert hehe

    The cookie functions follow. You would save the text as follows:

    var str = document.myFormName.myTextboxName.value;
    var expDate = new Date();
    expDate.setFullYear(expDate.getFullYear()+1);
    setCookie("myCookie", str, expDate, "/");

    You would retrieve the text as follows:

    var str = getCookie("myCookie");
    if (str) {
    document.myFormName.myTextboxName.value = str;
    } else {
    document.myFormName.myTextboxName.value = "";
    }

    Code:
    function getCookie(name) {
      var arg = name + "=";
      var alen = arg.length;
      var clen = document.cookie.length;
      var i = 0;
      while (i < clen) {
        var j = i + alen;
        if (document.cookie.substring(i, j) == arg)
          return getCookieVal (j);
        i = document.cookie.indexOf(" ", i) + 1;
        if (i == 0) break;
      }
      return null;
    }
    function getCookieVal(offset) {
      var endstr = document.cookie.indexOf (";", offset);
      if (endstr == -1)
        endstr = document.cookie.length;
      return unescape(document.cookie.substring(offset, endstr));
    }
    function setCookie(name, value) {
      var argv = setCookie.arguments;
      var argc = setCookie.arguments.length;
      var expires = (argc > 2) ? argv[2] : null;
      var path = (argc > 3) ? argv[3] : null;
      var domain = (argc > 4) ? argv[4] : null;
      var secure = (argc > 5) ? argv[5] : false;
      document.cookie = name + "=" + escape (value) + 
         ((expires == null) ? "" : ("; expires=" + expires.toGMTString())) + 
         ((path == null) ? "" : ("; path=" + path)) +  
         ((domain == null) ? "" : ("; domain=" + domain)) +    
         ((secure == true) ? "; secure" : "");
    }
    function delCookie(name) {
      exp = new Date();
      exp.setTime(exp.getTime() - (24*60*60*1000));
      var cval = getCookie(name);
      cval = (cval == null) ? "" : cval;
      document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString();
    }
