比如这样的。
<div id="showlog"></div>
<div id="hidediv">
这是即将隐藏的div12
</div>
<script>
var str = 'visited';

setCookie(str,_times);
document.getElementById('showlog').innerHTML = "time:"+getCookie(str);
if(parseInt(getCookie(str)) >= 3){
document.getElementById('hidediv').style.display = 'none';
}
function setCookie(c_name, value, expiredays) {
var exdate = new Date()
exdate.setDate(exdate.getDate() + expiredays)
document.cookie = c_name + "=" + escape(value) +
((expiredays == null) ? "" : ";expires=" + exdate.toGMTString())
}
