Question

我一直在搞乱这项任务，我很确定我完成了大约90％。

一切都运转正常，但由于某种原因，Cookies只是没有保存。

当我在输入字段中输入信息并按提交时，我会收到代码有效的警报。我通过一些验证软件运行它，它说一切都经过验证和工作。我给出的HTML页面代码和验证cookie（不确定我是否正确编码）说没有保存cookie。

我还使用FireFox中的开发人员命令来检查已保存的cookie列表，它表示此站点没有保存的cookie。有任何想法吗？

此时我在这里，加载页面时会弹出警告框，当我点击提交时，如何更改它，以便在我点击提交时才会弹出？

function addEvent(object, evName, fnName, cap) {
  if (object.attachEvent)
    object.attachEvent("on" + evName, fnName);
  else if (object.addEventListener)
    object.addEventListener(evName, fnName, cap);
}

function writeCookie(cName, cValue, expDate, cPath, cDomain, cSecure) {
  if (cName && cValue !== "") {
     var cString = cName + "=" + escape(cValue);
     if (expDate) 
        cString += ";expires=" + expDate.toGMTString();

     if (cPath) cString += ";path=" + cPath;
     if (cDomain) cString += ";domain=" + cDomain;
     if (cSecure) cString += ";secure";


     document.cookie = cString;
  }
  }

addEvent(window, "load", initPage, false);

  function initPage(){

    document.getElementById("sbutton").onclick = saveMailingInfo;
    console.log(document.cookie);



function saveMailingInfo() {

  var expire = new Date();
  expire.setFullYear(expire.getFullYear() + 3);

  var allFields = document.mailingForm.elements;
  for (var i  = 0; i < allFields.length; i++) {

    if (allFields[i].type == "text") {

      writeCookie(allFields[i].id, allFields[i].value, expire);

    }

    if (allFields[i].nodename == "SELECT") {

      writeCookie(allFields[i].id, allFields[i].selectedIndex, expire);

    }

    if (allFields[i].type == "radio" || allFields[i].type == "checkbox") {

  writeCookie(allFields[i].id, allFields[i].checked, expire);

}
  }
}
  alert("Cookie has been written!");
}
