如何使用 WebStorage 不显示任何内容

Question

您好，如果推荐人是 example.com，我想这样做，然后隐藏我正在使用网络存储但不工作的所有页面的一些数据

<script>


if (document.referrer !== 'example.com/') {
// Store
localStorage.setItem('displaynone', ' <style> 

.top-bar{display:none!important;}
.woocommerce-breadcrumb{display:none!important;}
.register-benefits{display:none!important;}
.before-login-text{display:none!important;}
#colophon{display:none!important;} </</style>');
}

localStorage.getItem('displaynone');




</script>

谁能告诉我怎么了？

你好，这段代码将帮助你玩 webstorage.js

    var cookieStoragePlan = {
        create: function(name, value, path, domain, expires){
    if(!name)
        return null;
    var cookie = (name) + '=';

    var time = new Date();
    time.setTime((new Date().getTime())+1000*60*60*24);

    if(typeof expires !== 'undefined'){
        time.setTime((new Date().getTime())+expires*1000);
    }

    cookie += typeof value === 'undefined' ? '' : encodeURIComponent(value);
    cookie += typeof path === 'undefined' ? '' : '; path=' + (path);
    //cookie += typeof domain === 'undefined' ? '; domain=' +       

    encodeURIComponent(document.domain)  : '; domain=' + encodeURIComponent(domain);
    cookie += '; expires=' + time.toUTCString();

    document.cookie = cookie;
    //console.log(document.cookie);
},

getValue: function(name){
    if(!name){
        return null;
    }
    var reg = new RegExp('(^| )' + name + '=([^;]*)(;|$)');
    var cookie = decodeURIComponent(document.cookie);
    var result = cookie.match(reg);
    return (!result ? null : result[2]);
},

isPresent: function(name){
    if(!name){
        return false;
    }
    var reg = new RegExp('(^| )' + name + '=([^;]*)(;|$)');
    return reg.test(decodeURIComponent(document.cookie));
},

remove: function(name){
    if(!name || this.isPresent(name)===false){
        return null;    
    }
    var time = new Date();
    time.setTime(0);
    var cookie = name + '=; expires=' + time.toUTCString(); 
    document.cookie = cookie;
},

clear: function(){
    var allCookie = decodeURIComponent(document.cookie);
    var row = allCookie.split('; ');
    for(var i = 0; i < row.length; ++i){
        var pos = row[i].indexOf('=');
        var key = row[i].substring(0, pos);
        this.remove(key);
    }
