PHP与JavaScript针对Cookie的读写、交互操作方法详解

3. js读取php的中文cookie，需要做 "decodeURIComponent (escape(php_cn_ck)) "函数处理
4. php读取js的中文cookie 需要做 "unescape()" 函数处理

cookie.js:

var Cookies = {};
/**
* 设置Cookies
*/
Cookies.set = function(name, value){
 var argv = arguments;
 var argc = arguments.length;
 var expires = (argc > 2) ? argv[2] : null;
 if(expires != null){
  var exp　　 = new Date();
  exp.setTime(exp.getTime() + 8*3600 + expires);
 }
 alert(exp.toGMTString());
 var path = (argc > 3) ? argv[3] : '/';
 var domain = (argc > 4) ? argv[4] : null;
  var secure = (argc > 5) ? argv[5] : false;
 document.cookie = name + "=" + escape (value) +
 ((expires == null) ? "" : ("; expires=" + exp.toGMTString())) +
 ((path == null) ? "" : ("; path=" + path)) +
 ((domain == null) ? "" : ("; domain=" + domain)) +
 ((secure == true) ? "; secure" : "");
};
/**
* 读取Cookies
*/
Cookies.get = function(name){
 var arg = name + "=";
 var alen = arg.length;
 var clen = document.cookie.length;
 var i = 0;
 var j = 0;
 while(i < clen){
  j = i + alen;
  if (document.cookie.substring(i, j) == arg)
  return Cookies.getCookieVal(j);
  i = document.cookie.indexOf(" ", i) + 1;
  if(i == 0)
  break;
 }
 return null;
};
/**
* 清除Cookies
*/
Cookies.clear = function(name) {
 if(Cookies.get(name)){
 var expdate = new Date();
 expdate.setTime(expdate.getTime() - (86400 * 1000 * 1));
 Cookies.set(name, "", expdate);
 }
};
Cookies.getCookieVal = function(offset){
 var endstr = document.cookie.indexOf(";", offset);
 if(endstr == -1){
  endstr = document.cookie.length;
 }
 return unescape(document.cookie.substring(offset, endstr));
};
