我正在创建一个JavaScript弹出窗口。代码如下。

HTML:

    <div id="ac-wrapper" style='display:none' onClick="hideNow(event)">
    <div id="popup">
        <center>
             <h2>Popup Content Here</h2>
            <input type="submit" name="submit" value="Submit" onClick="PopUp('hide')" />
        </center>
    </div>
</div>


CSS:

    #ac-wrapper {
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background: url("images/pop-bg.png") repeat top left transparent;
    z-index: 1001;
}
#popup {
    background: none repeat scroll 0 0 #FFFFFF;
    border-radius: 18px;
    -moz-border-radius: 18px;
    -webkit-border-radius: 18px;
    height: 361px;
    margin: 5% auto;
    position: relative;
    width: 597px;
}


剧本:

function PopUp(hideOrshow) {
    if (hideOrshow == 'hide') document.getElementById('ac-wrapper').style.display = "none";
    else document.getElementById('ac-wrapper').removeAttribute('style');
}
window.onload = function () {
    setTimeout(function () {
        PopUp('show');
    }, 0);
}

function hideNow(e) {
    if (e.target.id == 'ac-wrapper') document.getElementById('ac-wrapper').style.display = 'none';
}

问题:

上面的脚本可以正常工作,但是我需要使popUp在我的页面上仅出现一次。
即,当用户关闭弹出窗口时,直到用户重新启动浏览器或清除其缓存/ Cookie后,弹出窗口才应显示。

我尝试使用下面的cookie脚本,但是它对我不起作用。

<SCRIPT LANGUAGE="JavaScript">



<!-- Begin
var expDays = 1; // number of days the cookie should last

var page = "myPage.html";
var windowprops = "width=300,height=200,location=no,toolbar=no,menubar=no,scrollbars=no,resizable=yes";

function GetCookie (name) {
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen) {
var j = i + alen;
if (document.cookie.substring(i, j) == arg)
return getCookieVal (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function SetCookie (name, value) {
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");
}
function DeleteCookie (name) {
var exp = new Date();
exp.setTime (exp.getTime() - 1);
var cval = GetCookie (name);
document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString();
}
var exp = new Date();
exp.setTime(exp.getTime() + (expDays*24*60*60*1000));
function amt(){
var count = GetCookie('count')
if(count == null) {
SetCookie('count','1')
return 1
}
else {
var newcount = parseInt(count) + 1;
DeleteCookie('count')
SetCookie('count',newcount,exp)
return count
   }
}
function getCookieVal(offset) {
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}

function checkCount() {
var count = GetCookie('count');
if (count == null) {
count=1;
SetCookie('count', count, exp);

window.open(page, "", windowprops);

}
else {
count++;
SetCookie('count', count, exp);
   }
}
//  End -->
</script>

最佳答案

我在这种情况下最好使用localStorage而不是cookie。
localStorage具有更直观的界面,用户无法限制
要使用此功能。我已经更改了您的代码。

function PopUp(hideOrshow) {
    if (hideOrshow == 'hide') {
        document.getElementById('ac-wrapper').style.display = "none";
    }
    else  if(localStorage.getItem("popupWasShown") == null) {
        localStorage.setItem("popupWasShown",1);
        document.getElementById('ac-wrapper').removeAttribute('style');
    }
}
window.onload = function () {
    setTimeout(function () {
        PopUp('show');
    }, 0);
}


function hideNow(e) {
    if (e.target.id == 'ac-wrapper') document.getElementById('ac-wrapper').style.display = 'none';
}


这是工作的jsFiddle。
