Javascript插件,用于在任何浏览器中读取url的cookie值
您好,我是为浏览器编写插件的新手。我的要求是,我应该编写一个示例javascript插件代码来读取url的cookie值,并且它应该支持所有浏览器。我刚刚看到,我们无法直接从系统中的cookie文件读取数据,需要通过chrome的sqlite数据库进行读取。我被困在这里,任何帮助都将非常有用。使用此代码Javascript插件,用于在任何浏览器中读取url的cookie值,javascript,plugins,cookies,Javascript,Plugins,Cookies,您好,我是为浏览器编写插件的新手。我的要求是,我应该编写一个示例javascript插件代码来读取url的cookie值,并且它应该支持所有浏览器。我刚刚看到,我们无法直接从系统中的cookie文件读取数据,需要通过chrome的sqlite数据库进行读取。我被困在这里,任何帮助都将非常有用。使用此代码 $.cookie('the_cookie', 'the_value'); //Create expiring cookie, 7 days from then: $.cookie('the_co
$.cookie('the_cookie', 'the_value');
//Create expiring cookie, 7 days from then:
$.cookie('the_cookie', 'the_value', { expires: 7 });
//Create expiring cookie, valid across entire page:
$.cookie('the_cookie', 'the_value', { expires: 7, path: '/' });
//Read cookie
$.cookie('the_cookie'); // => 'the_value'
$.cookie('not_existing'); // => null
//Delete cookie by passing null as value:
$.cookie('the_cookie', null);
// Creating cookie with all availabl options
$.cookie('myCookie2', 'myValue2', { expires: 7, path: '/', domain: 'example.com',
secure: true, raw: true });
并从此URL下载jquery cookie()可以通过document.cookie以字符串格式访问cookie 一些例子: 你去看了吗
document.cookie = "YOUR_KEY_1=YOUR_VALUE_1;YOUR_KEY_2=YOUR_VALUE_2;..."
当你设置它时(一个接一个的cookie)
我为您创建了两个函数(get和set)以及如何使用它的示例。
(与IE6和Firefox 22兼容)
//cookie持续时间的定义
var my\u cookie\u duration\u hash={
天数:1,
小时:0,
分钟:0,
秒:0
};
//cookies键/值对的定义
var my_cookies={
键1:'value1=',
键2:“值2”
};
//让我们做些饼干
设置cookies(我的cookies、我的cookies、持续时间、散列“/”);
//我们去拿饼干吧
警告(获取cookies()['key1']);

对于(变量i=0;i
我希望它能有所帮助。你已经尝试了什么?@mishik:我尝试了w3学校的示例代码。下面是代码。函数getCookie(c_name){var c_value=document.cookie;var c_start=c_value.indexOf(“+c_name+”);if(c_start=-1){c_start=c_value.indexOf(c_name+”;}if(c_start=-1){c_value=null;}else{c_start=c_value.indexOf(“=”,c_start)+1;var c_end=c_value.indexOf(“;”,c_start);if(c_end==-1){c_end=c_value.length;}c_value=unescape(c_value.substring(c_start,c_end))}警报(c_value)返回c_value;}但我不确定这将如何帮助我必须使用javascript而不是jquery开发
console.log(document.cookie)
/* "YOUR_KEY=YOUR_VALUE; expires=EXPIRATION_DATE; path=WHERE_YOUR_COOKIE_WILL_BE_ACCESSIBLE"
eg.
user=599a9182df1...; expires=Tue, 15 Jul 2014 14:06:12 GMT; path=/logged_in
So, the cookie "user" as the value 599a9182df1... (Some SHA1 example)
It expires in 1 year (Won't be accessible if not renewed)
Is only accessible under /logged_in
