设置一个 jQuery cookie 只显示一次弹出窗口 [英] Set a jQuery cookie to show popup only once

问题描述

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

I'm an absolute newbie in jQuery. I'm learning, but there is a Christmas message that I need to get up and running within no time.

我已将这些包含在页面的标题中:

I've included these in the header of the page:

<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:

Then follows the message using a jQuery popup. Here it is:

<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>

在 body 中，我输入了以下信息:

In the body I've put the message:

<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.下一步是不要一遍又一遍地用相同的信息让我的回访者感到厌烦(推迟六十天就足够了).

So I want to set a cookie using the jQuery cookie plug-in:

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; }

Which is then found the next time a visitor hits the same page and the Christmas message is not shown till the message expires.

然后在访问者下次访问同一页面时找到它，并且直到消息过期才会显示圣诞节消息.

Now if-else statements are the higher kind of jQuery I'm not familiar with just yet. So, could anyone explain it to me?

现在 if-else 语句是我还不熟悉的高级 jQuery.那么，谁能给我解释一下?

解决方案

推荐答案

这样的事情可能会有所帮助:

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