webview, that uses mui looks like this when the real machine is running

:

html is as follows:

<nav class="mui-bar mui-bar-tab">
                    <a href="index.html" class="mui-tab-item mui-active" id="defaultTab">
                        <span class="mui-icon mui-icon-home"></span>
                        <span class="mui-tab-label"></span>
                    </a>
                    <a href="login.html" class="mui-tab-item">
                        <span class="mui-icon mui-icon-phone"></span>
                        <span class="mui-tab-label"></span>
                    </a>
                    <a href="main.html" class="mui-tab-item">
                        <span class="mui-icon mui-icon-email"></span>
                        <span class="mui-tab-label"></span>
                    </a>
                    <!--<a href="reg.html" class="mui-tab-item">
                        <span class="mui-icon mui-icon-gear"></span>
                        <span class="mui-tab-label"></span>
                    </a>-->
                </nav>

js is as follows:

var Index = 0;
        var subpages = ["index.html","login.html","main.html","reg.html"];
        mui.plusReady(function() {
            var self = plus.webview.currentWebview();
            for(var i=0;i<subpages.length;iPP){
                var sub = plus.webview.create(subpages[i],subpages[i],{top:"45px",bottom:"50px"});
                if(i != Index){
                    sub.hide();
                }
                self.append(sub);
            }
               //
            var activeTab = subpages[Index],title=document.querySelector(".mui-title");
            //
            mui(".mui-bar-tab").on("tap", "a", function(e) {
            //id
                var targetTab = this.getAttribute("href");
                if (targetTab == activeTab) {
                    return;
                }
                //
                title.innerHTML = this.querySelector(".mui-tab-label").innerHTML;
                //
                plus.webview.show(targetTab);
                //
                plus.webview.hide(activeTab);
                //
                activeTab = targetTab;
            })
        });

there are still many problems when using mui for the first time! Thank you!
