我在我的网站上设置了通知,

这是通知栏的jquery:

function showNotification(params){
    // options array
    var options = { 
        'showAfter': 0, // number of sec to wait after page loads
        'duration': 0, // display duration
        'autoClose' : false, // flag to autoClose notification message
        'type' : 'success', // type of info message error/success/info/warning
        'message': '', // message to dispaly
        'link_notification' : '', // link flag to show extra description
        'description' : '' // link to desciption to display on clicking link message
    }; 
    // Extending array from params
    $.extend(true, options, params);

    var msgclass = 'succ_bg'; // default success message will shown
    if(options['type'] == 'error'){
        msgclass = 'error_bg'; // over write the message to error message
    } else if(options['type'] == 'information'){
        msgclass = 'info_bg'; // over write the message to information message
    } else if(options['type'] == 'warning'){
        msgclass = 'warn_bg'; // over write the message to warning message
    } 

    // Parent Div container
    var container = '<div id="info_message" class="'+msgclass+'"><div class="center_auto"><div class="info_message_text message_area">';
    container += options['message'];
    container += '</div><div class="info_close_btn button_area" onclick="return closeNotification()"></div><div class="clearboth"></div>';
    container += '</div><div class="info_more_descrption"></div></div>';

    $notification = $(container);

    // Appeding notification to Body
    $('body').append($notification);

    var divHeight = $('div#info_message').height();
    // see CSS top to minus of div height
    $('div#info_message').css({
        top : '-'+divHeight+'px'
    });

    // showing notification message, default it will be hidden
    $('div#info_message').show();

    // Slide Down notification message after startAfter seconds
    slideDownNotification(options['showAfter'], options['autoClose'],options['duration']);

    $('.link_notification').live('click', function(){
        $('.info_more_descrption').html(options['description']).slideDown('fast');
    });

}
// function to close notification message
// slideUp the message
function closeNotification(duration){
    var divHeight = $('div#info_message').height();
    setTimeout(function(){
        $('div#info_message').animate({
            top: '-'+divHeight
        }); 
        // removing the notification from body
        setTimeout(function(){
            $('div#info_message').remove();
        },200);
    }, parseInt(duration * 3000));   

}

// sliding down the notification
function slideDownNotification(startAfter, autoClose, duration){    
    setTimeout(function(){
        $('div#info_message').animate({
            top: 0
        }); 
        if(autoClose){
            setTimeout(function(){
                closeNotification(duration);
            }, duration);
        }
    }, parseInt(startAfter * 5000));    
}

这是我在索引页面中添加的代码:

<script >
          function showAutoCloseMessage(){
             showNotification({
      message: "You cart total must be at least $200 for free shipping",
          autoClose: true,
          duration: 2
          });             
     }       
     $(document).ready(function() {
           showAutoCloseMessage();
       });                             
     </script>

现在我需要为此设置cookie。我需要,当用户进入网站时,该时间只显示通知栏,之后不显示。我的意思是,当用户重新加载网站时,不会显示通知栏。

任何人都可以帮助我吗?提前谢谢。

你可以使用cookie plugin 并把条件,

if ($.cookie('setCookie') == null) {
...
}
