设置一个jQuery cookie只显示一次弹出窗口

我是jQuery的绝对新手。我正在学习,但有一条圣诞节信息,我需要立即启动并运行。

我已将这些内容包含在页面标题中:

<script type="text/javascript" src="scripts/jquery-1.7.min.js"></script>
<script type="text/javascript" src="scripts/jquery.cookies.2.2.0.min.js"></script>` 

然后使用jQuery弹出窗口跟随消息。这是:

<script type="text/javascript">
$(document).ready(function() {  
        var id = '#dialog';

        //Get the screen height and width
        var maskHeight = $(document).height();
        var maskWidth = $(window).width();

        //Set height and width to mask to fill up the whole screen
        $('#mask').css({'width':maskWidth,'height':maskHeight});

        //transition effect     
        $('#mask').fadeIn(1000);    
        $('#mask').fadeTo("slow",0.7);  

        //Get the window height and width
        var winH = $(window).height();
        var winW = $(window).width();

        //Set the popup window to center
        $(id).css('top',  winH/2-$(id).height()/2);
        $(id).css('left', winW/2-$(id).width()/2-220);

        //transition effect
        $(id).fadeIn(2000);     

    //if close button is clicked
    $('.window .close').click(function (e) {
        //Cancel the link behavior
        e.preventDefault();

        $('#mask').hide();
        $('.window').hide();
    });     

    //if mask is clicked
    $('#mask').click(function () {
        $(this).hide();
        $('.window').hide();
    });     

});

</script>

body中,我发了以下信息:

<div style="top: 199.5px; left: 200px; display: none;" id="dialog" class="window">  
XMAS MESSAGE
<a href="#" class="close">Shut this popup.</a>
</div>

到目前为止一切顺利。下一步不是一遍又一遍地给我的回访者带来同样的信息(推迟六十天就足够了)。

所以我想使用jQuery cookie插件设置一个cookie:

function setCookie() {
    $.cookie('test_status', '1', { path: '/', expires: 60 });
    return false;
}

下次访问者访问同一页面时会发现该消息,并且在消息过期之前不会显示圣诞消息。

现在if-else语句是我不熟悉的更高级的jQuery。那么,有人可以向我解释一下吗?

这种东西可能会有所帮助:

$(document).ready(function(){
   if ($.cookie('test_status') != '1') {
    //show popup here
    $.cookie('test_status', '1', { expires: 60}); }
   });

首先包括jquery库。

在jquery中包含以下用于cookie的脚本。

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-cookie/1.4.1/jquery.cookie.min.js"></script>

现在将以下代码放入页脚:

$(document).ready(function() {
       // initially popup is hidden:
        $('#stay-in-toch.popup-outer').hide();
        // Check for the "whenToShowDialog" cookie, if not found then show the dialog and save the cookie.
        // The cookie will expire and every 2 days and the dialog will show again.
        if ($.cookie('whenToShowDialog') == null) {
            // Create expiring cookie, 2 days from now:
            $.cookie('whenToShowDialog', 'yes', { expires: 2, path: '/' });

            // Show dialog
             $('#stay-in-toch.popup-outer').show();       
        }
    });

你可以试试这个

$(document).ready(function() {  
    if ($.cookie('test_status')) {
        return;
    }

    //Rest of your code here
});

我有同样的问题,我找到了这个解决方案:

$(document).ready(function () {
    var cookie = document.cookie;
    if (cookie == "") {
        //show popup depending on url
        var url = window.location;
        if (url != "http://localhost/test/jquery-popup.html") {                                    
            setTimeout(function () {
                $.fn.colorbox({ html: '<div style="width:301px;height:194px;"><a href="http://livebook.in/"><img src="res/homer.jpg" style="width:301px;height:194px;" alt="The linked image" /></a></div>', open: true });
            }, 500);   
        }else {
            setTimeout(function () {
                $.fn.colorbox({html:'...', open:true});
            }, 500);
        }

        //set timeout for closing the popup
        setTimeout(function () { $.fn.colorbox.close(); }, 3000);

        //set cookie
        var d = new Date();
        d.setTime(d.getTime() + (30 * 24 * 60 * 60 * 1000)); //expire in 30 days
        var expires = "expires=" + d.toGMTString();
        document.cookie = "apparsoYES" + "=" + "YES" + "; " + expires;    
    }
});

此脚本在页面加载时创建一个弹出窗口,自动关闭它,创建一个cookie,使popoup只显示一次,并根据页面显示不同的弹出窗口

我想你要找的是,当新用户访问你的Webpage时,你会弹出一个弹出窗口,但是当他浏览其他页面时,弹出窗口不应该出现。

通过cookies很容易实现,请查看此代码示例,这将对您有所帮助

所以我要包含所使用的代码段(您也可以按照以下链接进行操作)

所以,脚本部分是

var expDays = 1; // number of days the cookie should last

var page = "only-popup-once.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);
   }
}

以下将是DOM的主体,

<BODY OnLoad="checkCount()">

受到其他答案的启发,我做了这些工作,我花了很长的时间才能解决,因此可能会对其他人有所帮助。如果有人想编辑和改进我的代码,请随意。

 <script type="text/javascript">
function setCookie() {
    Cookies.set('test_status', '1', { expires: 1 })
    return false;
}
</script>

$(document).ready(function(){
   if (Cookies.get('test_status') != '1') {
         setTimeout(function(){

            src: '#message_popup' //ID OF INLINE ELEMENT
