顶部选项卡-可左右拖动(webview)示例如何做到tab与webview联动滚动

顶部选项卡-可左右拖动(webview)的示例中，如何做到tab与webview联动滚动，效果类似uc头条一样

ps：自己也不确定有多少了到航头，页面怎么办，到航头从后台获取，页面不可能建N多个.html

<header class="mui-bar mui-bar-nav">
            <!--<a class="mui-action-back mui-icon mui-icon-left-nav mui-pull-left"></a>-->
            <h1 class="mui-title">选项卡练习(webview)</h1>
        </header>

mui.plusReady(function() {
                var items = [];
                for(var i = 1; i <= 7; i++) {
                    items.push({
                        id: '' + i + '.html',
                        url: 'pages/' + i + '.html',
                        extras: {}
                    })
                }

                var currentId = plus.webview.currentWebview().id;
                var group = new webviewGroup(currentId, {
                    items: items,
                    onChange: function(obj) {
                        var c = document.querySelector(".mui-control-item.mui-active");
                        if(c) {
                            c.classList.remove("mui-active");
                        }
                        document.querySelector(".mui-scroll .mui-control-item:nth-child(" + (parseInt(obj.index) + 1) + ")").classList.add("mui-active");
                    }
                });

                mui(".mui-scroll").on("tap", ".mui-control-item", function(e) {
                    var wid = this.getAttribute("data-wid");
                    group.switchTab(wid);
                });
            });

在滚动过程中，item数组里有三个参数

id: "",
url: "",
extras: {}

第一个参数 id 是我们主要用来切换的，获取到的 data-wid 与id 对比并跳转 url
