JavaScript处理cookie

如下使用了jQuery.cookie的插件:有三个参数来使用

jQuery.cookie = function(name, value, options) {
    if (typeof value != 'undefined') { // name and value given, set cookie
        options = options || {};
        if (value === null) {
            value = '';
            options.expires = -1;
        }
        var expires = '';
        if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) {
            var date;
            if (typeof options.expires == 'number') {
                date = new Date();
                date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000));
            } else {
                date = options.expires;
            }
            expires = '; expires=' + date.toUTCString(); // use expires attribute, max-age is not supported by IE
        }
        // CAUTION: Needed to parenthesize options.path and options.domain
        // in the following expressions, otherwise they evaluate to undefined
        // in the packed version for some reason...
        var path = options.path ? '; path=' + (options.path) : '';
        var domain = options.domain ? '; domain=' + (options.domain) : '';
        var secure = options.secure ? '; secure' : '';
        document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join('');
    } else { // only name given, get cookie
        var cookieValue = null;
        if (document.cookie && document.cookie != '') {
            var cookies = document.cookie.split(';');
            for (var i = 0; i < cookies.length; i++) {
                var cookie = jQuery.trim(cookies[i]);
                // Does this cookie string begin with the name we want?
                if (cookie.substring(0, name.length + 1) == (name + '=')) {
                    cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                    break;
                }
            }
        }
        return cookieValue;
    }
};

js是上面的三个值来设置cookies的,name  value  time

//如下是js直接去取Cookie的值.

if($.cookie("uu_upload_tip"+login_id)){
}else{
   checkUploaded();

}

//js设置Cookie的值
function uu_upload_setCookie(){
 $.cookie("uu_upload_tip"+login_id,1,{expires:24});
 $("#index_upload_tip").hide();
} 

 

 

顺带小山同学的杰作一份,同样是cookies的设置:

//设置cookies函数

function setcookie ( name , value )

{

    var Days = 30 ;

     var exp   = new Date ();    

    exp . setTime ( exp . getTime () + Days * 24 * 60 * 60 * 1000 );

   document . cookie = name + "=" + escape ( value ) + ";expires=" + exp . toGMTString ();

}

//取cookies函数      

function getcookie ( name )  

{

     var arr = document . cookie . match ( new RegExp ( "(^| )" + name + "=([^;]*)(;|$)" ));

    if ( arr != null ) return unescape ( arr [ 2 ]); return null ;

}

//删除cookie

function delcookie ()

{

var name = "comparelist" ;

    var exp = new Date ();

   exp . setTime ( exp . getTime () - 1 );

    var cval = getcookie ( name );

    document . getElementById ( "comparelist" ). innerHTML = '' ;

    if ( cval != null ) document . cookie = name + "=" + cval + ";expires=" + exp .toGMTString ();

}
