• cookie的操作


    比如这样如果一个网站上有两个域名的时候,我们需要考虑,两个域名下的cookie.

    我们所说的跨域只的就是lesport.com和le.com 

    js的cookie是不能跨域的,为了防止过大。

    js增加删除和查找网上一大堆。下面有推荐的。

    我们需要明白增加的时候,比如服务器已经有返回的cookie,我们在前端需要临时增加一个,一定要添加在一级域名下(二级域名也可以添加)

    var Cookie = {
    set: function(name, value, opt){
    opt || (opt = {});
    var t = new Date(), exp = opt.exp;
    if(typeof exp==='number'){
    t.setTime(t.getTime() + exp*3600000); //60m * 60s * 1000ms
    }else if(exp==='forever'){
    t.setFullYear(t.getFullYear()+50); //专业种植cookie 50年
    }else if(value===null){ //删除cookie
    value = '';
    t.setTime(t.getTime() - 3600000);
    }else if(exp instanceof Date){ //传的是一个时间对象
    t = exp;
    }else{
    t = '';
    }
    document.cookie = name+'='+encodeURIComponent(value)+(t && '; expires='+t.toUTCString())+
    '; domain='+(opt.domain || '.le.com')+'; path='+(opt.path || '/')+(opt.secure ? '; secure' : '');
    },
    get: function(name){
    name += '=';
    var cookies = (document.cookie || '').split(';'),
    cookie,
    nameLength = name.length,
    i = cookies.length;
    while(i--){
    cookie = cookies[i].replace(/^s+/,'');
    if(cookie.slice(0,nameLength)===name){
    return decodeURIComponent(cookie.slice(nameLength)).replace(/s+$/,'');
    }
    }
    return '';
    }
    };
    function cookieTool(name, value, options) {
    if(typeof value==='undefined'){
    return Cookie.get(name);
    }
    if(options){
    options.exp = typeof options.expires==='number' ? options.expires * 24 :
    options.expires; //原来的cookie是按天算的
    }
    Cookie.set(name, value, options);
    }
    function getQuery(key, url) {
    var urlArgs = url || location.search;
    if (urlArgs.length > 0 && urlArgs.indexOf("?") != -1) {
    var regex = new RegExp(key + "=([^&]*)", "i"),
    result = urlArgs.match(regex);
    return (result && result.length > 0) ? unescape(result[1]) : null;
    }
    return null;
    }
    function handler(data){
    if(data && data.vast){
    var cuid = data.vast.cuid;
    var le_cookie = cookieTool('ark_uuid');
    if(location.host.indexOf('.le.com') >= 0 && cuid && (!le_cookie || le_cookie != cuid)){
    cookieTool('ark_uuid',cuid,{
    'expires':new Date(2060,00,01, 08,00,01),
    'domain':'.le.com'
    });
    //广告用户cookie设置到le.com成功后发送检测
    var srcType = '';
    var purl = getQuery('purl',location.href) || '';
    if(purl.indexOf('.lesports.com') > 0)
    srcType = 'http://ark.letv.com/apsdbg/cm/sport?url=';
    else
    srcType = 'http://ark.letv.com/apsdbg/cm/cloud?url=';

    var img = document.createElement("img");
    img.src = srcType + encodeURIComponent(purl);
    img.onload = function(){
    img = null;
    }
    }
    }
    };
    var url = 'http://ark.letv.com/s?ark=0&ct=0&n=0&res=jsonp&j=handler&callback=handler';
    var script = document.createElement('script');
    script.setAttribute('src', url);
    document.getElementsByTagName('head')[0].appendChild(script);
