javascript 写cookie

注意：请在Apache或者tomcat环境下测试

<script language="javascript">

function SetCookie(sName, sValue){
date = new Date();
date.setFullYear(date.getFullYear()+1);
document.cookie = sName + "=" + escape(sValue) + "; expires=" + date.toGMTString();
}

function GetCookie(sName){
var aCookie = document.cookie.split("; ");
for (var i=0; i < aCookie.length; i++){
var aCrumb = aCookie[i].split("=");
if (sName == aCrumb[0]) return unescape(aCrumb[1]);
}
return null;
} 

SetCookie('abcd',1234); // 写cookie

alert(GetCookie('abcd')); // 读cookie
</script>
