在用户关闭会话之前显示基于会话的DIV

我试图向用户显示DIV,直到他/她关闭它。用户点击close后,DIV将保持关闭24小时。

这是每24小时显示一次的工作代码。但是,我不确定如何添加点击功能:

<?php
    if (!isset($_COOKIE['cookie'])) {
        setcookie('cookie', true, time() + 3600 * 24); // Save a cookie for 1 day
        echo '<div class="slideshow"><span class="close">close</span>Hello World</div>';
    }
?>

你应该尝试这样的事情。

$(document).ready(function() {

  // If the 'hide cookie is not set we show the message
  if (!readCookie('hide')) {
    $('#popupDiv').show();
  }

  // Add the event that closes the popup and sets the cookie that tells us to
  // not show it again until one day has passed.
  $('#close').click(function() {
    $('#popupDiv').hide();
    createCookie('hide', true, 1)
    return false;
  });

});

// ---
// And some generic cookie logic
// ---
function createCookie(name,value,days) {
  if (days) {
    var date = new Date();
    date.setTime(date.getTime()+(days*24*60*60*1000));
    var expires = "; expires="+date.toGMTString();
  }
  else var expires = "";
  document.cookie = name+"="+value+expires+"; path=/";
}

function readCookie(name) {
  var nameEQ = name + "=";
  var ca = document.cookie.split(';');
  for(var i=0;i < ca.length;i++) {
    var c = ca[i];
    while (c.charAt(0)==' ') c = c.substring(1,c.length);
    if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
  }
  return null;
}

function eraseCookie(name) {
  createCookie(name,"",-1);
}
