使用Javascript阅读Cookies [英] Read Cookies using Javascript

问题描述

我想使用php创建一个cookie，我也需要使用javascript.ie，
通过使用setcookie（'mycookie'，'hello'，time（）+ 34000）在我的系统中创建一个cookie。现在，我需要阅读它使用javascript.Is这可能吗？如果有人知道，请给我一些idea.Please ....帮助我。我使用javscript如下

 < script language =javascript> 
 
函数Get_Cookie（check_name）{
 //首先我们将这个cookie分成名/值对
 //注意：document.cookie只返回name = value，不是其他组件
 var a_all_cookies = document.cookie.split（';'）; 
 var a_temp_cookie =''; 
 var cookie_name =''; 
 var cookie_value =''; 
 var b_cookie_found = false; // set boolean t / f default f 
 
 for（i = 0; i  {
 //现在我们将name = value pair 
 a_temp_cookie = a_all_cookies [i] .split（'='）; 
 
 
 //和修剪左/右空白，当我们在它
 cookie_name = a_temp_cookie [0] .replace（/ ^ \s + | \s + $ / G， ''）; 
 
 //如果提取的名称匹配传递check_name 
 if（cookie_name == check_name）
 {
 b_cookie_found = true; 
 //我们需要处理cookie没有值但存在（no = sign，也就是）的情况：
 if（a_temp_cookie.length> 1）
 {
 cookie_value = unescape（a_temp_cookie [1] .replace（/ ^ \s + | \s + $ / g，''））; 
} 
 //注意，在初始化cookie但没有值的情况下，返回null 
 return cookie_value; 
 break; 
} 
 a_temp_cookie = null; 
 cookie_name =''; 
} 
 if（！b_cookie_found）
 {
 return null; 
} 
} 
 if（Get_Cookie（'__ gsb'））
 {
 alert（'Found'）; 
} 
< / script>`
  

解决方案>

这是一个很好的帖子它演示了这种情况。为了通过脚本语言（如javascript）访问cookie，必须将 HttpOnly 属性设置为 false 。这是 setcookie 功能的最后一个参数。

I want to create a cookie using php,an also i need to read it using javascript.ie, by using setcookie('mycookie','hello',time()+34000) in php i am creating a cookie in my system.Now,i need to read it using javascript.Is it possible?If anybody knows please give me some idea.Please....help me.I am using javscript as follows

<script language="javascript">

    function Get_Cookie( check_name ) {
    // first we'll split this cookie up into name/value pairs
    // note: document.cookie only returns name=value, not the other components
    var a_all_cookies = document.cookie.split( ';' );
    var a_temp_cookie = '';
    var cookie_name = '';
    var cookie_value = '';
    var b_cookie_found = false; // set boolean t/f default f

    for ( i = 0; i < a_all_cookies.length; i++ )
    {
        // now we'll split apart each name=value pair
        a_temp_cookie = a_all_cookies[i].split( '=' );


        // and trim left/right whitespace while we're at it
        cookie_name = a_temp_cookie[0].replace(/^\s+|\s+$/g, '');

        // if the extracted name matches passed check_name
        if ( cookie_name == check_name )
        {
            b_cookie_found = true;
            // we need to handle case where cookie has no value but exists (no = sign, that is):
            if ( a_temp_cookie.length > 1 )
            {
                cookie_value = unescape( a_temp_cookie[1].replace(/^\s+|\s+$/g, '') );
            }
            // note that in cases where cookie is initialized but no value, null is returned
            return cookie_value;
            break;
        }
        a_temp_cookie = null;
        cookie_name = '';
    }
    if ( !b_cookie_found )
    {
        return null;
    }
}
 if (Get_Cookie('__gsb'))
   {
alert('Found');
}
</script>`

解决方案

Here's a nice post that demonstrates this scenario. In order to make a cookie accessible through scripting languages such as javascript it must have the HttpOnly property set to false. This is the last parameter of the setcookie function.
