jqury关于cooke的操作写入cookie后只显示一次的DIV提示框代码

 有时候当用户登录系统后，需要给用户弹出提示框，但是不需要总是弹出来，在这里加入访问cookie来判断是否弹出过提示框，如果弹出过那么保存cookie，下次根据cookie是否存在来判断是否弹出

 

<script type="text/javascript">
function cookiesave(n, v, mins, dn, path){if(n){if(!mins) mins = 365 * 24 * 60;if(!path) path = "/";var date = new Date();date.setTime(date.getTime() + (mins * 60 * 1000));var expires = "; expires=" + date.toGMTString();if(dn) dn = "domain=" + dn + "; ";document.cookie = n + "=" + v + expires + "; " + dn + "path=" + path;}
}
function cookieget(n){var name = n + "=";var ca = document.cookie.split(';');for(var i=0;i<ca.length;i++) {var c = ca[i];while (c.charAt(0)==' ') c = c.substring(1,c.length);if (c.indexOf(name) == 0) return c.substring(name.length,c.length);}return "";
}
function closeclick(){document.getElementById('note').style.display='none';cookiesave('closeclick','closeclick','','','');
}
function clickclose(){if(cookieget('closeclick')=='closeclick'){document.getElementById('note').style.display='none';}else{document.getElementById('note').style.display='block';}
}
window.onload=clickclose;
</script>
