cookie.js檔案

偶爾發現ExtJS中有操作cookie的js方法，拿來給大家分享下。</p><p>var Cookies = {};<br />Cookies.set = function(name, value){<br /> var argv = arguments;<br /> var argc = arguments.length;<br /> var expires = (argc > 2) ? argv[2] : null;<br /> var path = (argc > 3) ? argv[3] : '/';<br /> var domain = (argc > 4) ? argv[4] : null;<br /> var secure = (argc > 5) ? argv[5] : false;<br /> document.cookie = name + "=" + escape (value) +<br /> ((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +<br /> ((path == null) ? "" : ("; path=" + path)) +<br /> ((domain == null) ? "" : ("; domain=" + domain)) +<br /> ((secure == true) ? "; secure" : "");<br />};</p><p>Cookies.get = function(name){<br />var arg = name + "=";<br />var alen = arg.length;<br />var clen = document.cookie.length;<br />var i = 0;<br />var j = 0;<br />while(i < clen){<br />j = i + alen;<br />if (document.cookie.substring(i, j) == arg)<br />return Cookies.getCookieVal(j);<br />i = document.cookie.indexOf(" ", i) + 1;<br />if(i == 0)<br />break;<br />}<br />return null;<br />};</p><p>Cookies.clear = function(name) {<br /> if(Cookies.get(name)){<br /> document.cookie = name + "=" +<br /> "; expires=Thu, 01-Jan-70 00:00:01 GMT";<br /> }<br />};</p><p>Cookies.getCookieVal = function(offset){<br /> var endstr = document.cookie.indexOf(";", offset);<br /> if(endstr == -1){<br /> endstr = document.cookie.length;<br /> }<br /> return unescape(document.cookie.substring(offset, endstr));<br />};

樣本：
