104;Q:用 javascript 操作 Cookie 示例
A:
//写 Cookie(用分号“;”把表达式“var=value”分隔开)
function Write2Cookie()
{ document。cookie=〃v1=123;〃 + 〃path=/;〃;
document。cookie=〃v2=321;〃 + 〃path=/;〃;
}
//读 Cookie
function getCookieVal(name)
{
var firstCharPos;lastCharPos;
var theBigCookie = document。cookie;
firstCharPos = theBigCookie。indexOf(name);
if(firstCharPos != …1)
{//skip 'name' and '='。
firstCharPos +=name。length + 1;
//Find the end of the value string (i。e。 the next';')。
lastCharPos = theBigCookie。indexOf(';'; firstCharPos);
if(lastCharPos == …1) lastCharPos = theBigCookie。length;
//Return thevalue。
return theBigCookie。substring(firstCharPos; lastCharPos);
}
else
{ return false;}
}
thev1=getCookieVal('v1') // read
thev2=getCookieVal('v2') // read
