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>
在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}); } });
答案 1 :(得分:3)
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
});
答案 3 :(得分:0)
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。
