使用Javascript閱讀Cookie

我想用php創建一個cookie,我還需要用javascript.ie讀取它, 通過在php中使用setcookie('mycookie','hello',time()+ 34000)我在我的系統中創建一個cookie。現在,我需要使用javascript閱讀它。是否有可能?如果有人知道請給我一些idea.Please ....幫助我。我正在使用javscript如下

<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>`

最佳答案

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.
