Set cookie domain with Javascript variable
提问by CLiown
Im taking the domain from the HTML of the page using jQuery:
我使用 jQuery 从页面的 HTML 中获取域：
domainUrl = $("p.domain").text();
for the purposes of testing:
为测试目的：
<p class="domain">.vl3.co.uk</p>
Which is also the domain Im testing the script on.
这也是我测试脚本的域。
This then give an alert containing the correct domain:
然后给出一个包含正确域的警报：
alert(domainUrl);
I want to the use that variable to set the domain in a cookie:
我想使用该变量在 cookie 中设置域：
set_cookie('visible', 'no', 2020, 1, 1, '/', '+domainUrl+');
Here is the set cookie function:
这是设置cookie函数：
function set_cookie ( name, value, exp_y, exp_m, exp_d, path, domain, secure ) {
var cookie_string = name + "=" + escape ( value );
if ( exp_y ) {
var expires = new Date ( exp_y, exp_m, exp_d );
cookie_string += "; expires=" + expires.toGMTString();
}
if ( path )
cookie_string += "; path=" + escape ( path );
if ( domain )
cookie_string += "; domain=" + escape ( domain );
if ( secure )
cookie_string += "; secure";
document.cookie = cookie_string;
}
Why doesnt the cookie domain get set?
为什么没有设置cookie域？
I think the problem is how im using the domainUrl variable when setting the cookie?
我认为问题是我在设置 cookie 时如何使用 domainUrl 变量？

It should be: set_cookie('visible', 'no', 2020, 1, 1, '/', domainUrl);
应该是： set_cookie('visible', 'no', 2020, 1, 1, '/', domainUrl);
Pls, try this extension, it works, it comprises all that:
请试试这个扩展，它有效，它包括所有内容：
http://plugins.jquery.com/project/Cookie
http://plugins.jquery.com/project/Cookie
Then you only have to write:
然后你只需要写：
$.cookie('the_cookie', 'the_value', { expires: 7, path: '/', domain: 'jquery.com' });

Use jquery Annex library
使用jquery附件库
I think this is the best way to get and set cookies using jQuery:
我认为这是使用 jQuery 获取和设置 cookie 的最佳方式：
// cookie [writes and reads cookies]
//set cookie
$.cookie('kittencookie', 'fluffy', {expires : 7});
//get cookie
var kittenCookieValue = $.cookie('kittencookie');
