Question

如何使用jquery或php在一天内显示一次FB likebox。我已经完成了弹出，我想在浏览器中保存会话或cookie。所以我可以使事情正常工作。目前我正在使用jquery和php。

<body onload="openOffersDialog();">
<script type="text/javascript" src="popup.js"></script>
<?php 
    if(!isset($_SESSION['jquery_popup']))  
    { 
    $_SESSION['jquery_popup'] = "sessionexists";

        echo $_SESSION['jquery_popup'];


    ?>
<script type="text/javascript">
function openOffersDialog() {
    $('#overlay').fadeIn('fast', function() {
        $('#boxpopup').css('display','block');
        $('#boxpopup').animate({'left':'30%'},500);
    });
}


function closeOffersDialog(prospectElementID) {
    $(function($) {
        $(document).ready(function() {
            $('#' + prospectElementID).css('position','absolute');
            $('#' + prospectElementID).animate({'left':'-100%'}, 500, function() {
                $('#' + prospectElementID).css('position','fixed');
                $('#' + prospectElementID).css('left','100%');
                $('#overlay').fadeOut('fast');
            });
        });
    });
}
</script>

<div id="overlay" class="overlay"></div>
<!--<a onclick="openOffersDialog();">Click Here To See The PopUp</a>-->
<div id="boxpopup" class="box">

    <a onclick="closeOffersDialog('boxpopup');" class="boxclose"></a>
    <div id="content">

    <h2>Like us on Facebook</h2>
    <iframe src="http://www.facebook.com/plugins/likebox.php?href=http%3A%2F%2Fwww.facebook.com%2Fkornerseat&amp;width&amp;height=290&amp;colorscheme=light&amp;show_faces=true&amp;header=true&amp;stream=false&amp;show_border=true&amp;appId=474663095902746" scrolling="no" frameborder="0" style="border:none; overflow:hidden; height:290px;" allowTransparency="true"></iframe>

    </div>
</div>
<?php
    }
?>

Answer 1

在php代码中按照之前的方式添加你的fb Like按钮

<?php 
  if(!isset($_SESSION['jquery_popup']))  
  { 
    $_SESSION['jquery_popup'] = "sessionexists";
    echo '<iframe src="http://www.facebook.com/plugins/likebox.php?href=http%3A%2F%2Fwww.facebook.com%2Fkornerseat&amp;width&amp;height=290&amp;colorscheme=light&amp;show_faces=true&amp;header=true&amp;stream=false&amp;show_border=true&amp;appId=474663095902746" scrolling="no" frameborder="0" style="border:none; overflow:hidden; height:290px;" allowTransparency="true"></iframe>';
  }
?>

注意：假设您之前没有销毁会话变量。

你想要使用一个cookie，简单地将它设置为24小时后死亡，然后检查它是否已经过期，如果它再次显示弹出窗口

//取自http://www.w3schools.com/

的Javascript版本示例

function setCookie(cname,cvalue,exdays)
{
var d = new Date();
d.setTime(d.getTime()+(exdays*24*60*60*1000));
var expires = "expires="+d.toGMTString();
document.cookie = cname + "=" + cvalue + "; " + expires;
}

function getCookie(cname)
{
var name = cname + "=";
var ca = document.cookie.split(';');
for(var i=0; i<ca.length; i++) 
  {
  var c = ca[i].trim();
  if (c.indexOf(name)==0) return c.substring(name.length,c.length);
  }
return "";
}
if(getCookie('jquery_popup') ==""){
setCookie('jquery_popup','sessionexists',1);
//Add code to display popup here
}

PHP方法

if(!isset($_COOKIE['jquery_popup'])){
setcookie("jquery_popup", 'sessionexists', time()+3600*24); 
//Add code to display popup here
}
