我已經編寫了將Cookie保存在JavaScript中的代碼?，F(xiàn)在，無論我分配的值如何，都需要清除cookie。是否有任何腳本模塊可刪除Javascript生成的所有cookie ？我的示例代碼：document.cookie = 'ppkcookie2=another test; expires=Fri, 3 Aug 2001 20:47:11 UTC; path=/'function createCookie(name,value,days) {    if (days) {        var date = new Date();        date.setTime(date.getTime()+(days*24*60*60*1000));        var expires = "; expires="+date.toGMTString();    }    else var expires = "";    document.cookie = name+"="+value+expires+"; path=/";}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 c.substring(nameEQ.length,c.length);    }    return null;}function eraseCookie(name) {    createCookie(name,"",-1);}我還能如何清除所有cookie？當我在網絡服務器上測試代碼時會出現(xiàn)任何問題嗎？
