我不知道如何删除cookie.我想要的是当我提交表格时.cookie也被删除.我尝试了delete_cookie("名称"),但是没有用.我认为因为我创建的cookie javascript.请检查我的代码以解决此问题.

function setCookie(cookieName, cookieValue, nDays) {
    var today = new Date();
    var expire = new Date();

    if (!nDays) 
        nDays=1;

    expire.setTime(today.getTime() + 3600000*24*nDays);
    document.cookie = cookieName+"="+escape(cookieValue) + ";expires="+expire.toGMTString();
}

function readCookie(name) {
  var nameEQ = name + "=";
  var ca = document.cookie.split(';');
  for(var i = 0; i < ca.length; i++) {
    var c = ca[i];
    while (c.charAt(0) == ' ') c = c.substring(1, c.length);
    if (c.indexOf(nameEQ) == 0) return …
