js操作cookie （转）

//网页引用

<script language="javascript"src="./js/cookie.js"></script>

//取cookie值

var hrckdeptcode = Cookie("hrckdeptcode");

var hrckdeptname = Cookie("hrckdeptname");

//保存cookie值

setCookie("hrckdeptcode", deptcode, expdate, "/", null, false);

setCookie("hrckdeptname", deptname, expdate, "/", null, false);

把下面的脚本放到 cookie.js 文件里

var expdate= new Date();

function getCookieVal (offset) {

var endstr = document.cookie.indexOf (";", offset);

if (endstr == -1) endstr = document.cookie.length;

return unescape(document.cookie.substring(offset, endstr));

}

function Cookie (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 setCookie (name,value,expires,path,domain,secure) {

expdate.setTime(expdate.getTime() + (24*60*60*1000*365));

document.cookie = name + "=" + escape (value) +

((expires) ? "; expires=" + expires.toGMTString() : "") +

((path) ? "; path=" + path : "") +

((domain) ? "; domain=" + domain : "") +

((secure) ? "; secure" : "");

}

function deleteCookie(name) {

expdate = new Date();

expdate.setTime(expdate.getTime() - (86400 * 1000 * 1));

setCookie(name, "", expdate);

}
