js操作COOKIE

Question

ＪＳ改变菜单，已近完成了～～但是刷新后就还原了～
所以我用cookie来保存

这是我的小案例~~

<script language="JavaScript" type="text/javascript"> 
 document.aa="userId=828"; 
 var bb=document.aa;  
 var cc=bb.split("="); 
 var abc;  
 if("userId"==cc[0])
 { 
  acb=cc[1]; 
  break; 
 } 
 alert(abc); 
</script>

我想获取后面的828  但是老是获取不了~~
所以请教下

Answer 1

你上面的代码和COOKIE没关系吧？document.aa="userId=828"; ？＂}&nbsp;&nbsp;;&nbsp;</script>＂？语法错了吧.我定义了函数，传入COOKIE名获取值：测试：if (jQuery("#checkCode").val() !=&nbsp;operatorCookie("CheckCode")) ...函数：//获取指定名的Cookiefunction operatorCookie(cookieName) {&nbsp;&nbsp;&nbsp; var strCookie = document.cookie;&nbsp;&nbsp;&nbsp; var arrCookie = strCookie.split("; ");&nbsp;&nbsp;&nbsp; var tempName = cookieName; ;&nbsp;&nbsp;&nbsp; for (var i = 0; i < arrCookie.length; i++) {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; var arr = arrCookie[i].split("=");&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (tempName == arr[0]) {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; tempName = arr[1];&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; break;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;&nbsp;&nbsp; }&nbsp;&nbsp;&nbsp; return tempName;}
