登录页面进index主页之后，主页点侧滑菜单就变成了登录页面

把当前的登陆页close(),hide()都没用，index页面也设置了zindex=0，

document.getElementById("go-index").addEventListener('tap',function(){  
                    var ww= plus.webview.currentWebview();  
                    plus.webview.hide(ww);  
                    mui.openWindow({  
                        id:'index',  
                        styles: {  
                                zindex: 0  
                            }  
                        });  
    });

主页面上的侧滑是直接抄的mui

main = plus.webview.currentWebview();  
main.addEventListener("maskClick", closeMenu);  

setTimeout(function() {  
                        menu = mui.preload({  
                            url: 'sidebar.html',  
                            id: 'sidebar',  
                            styles: {  
                                left: 0,  
                                width: '70%',  
                                zindex: -1  
                            },  
                            show: {  
                                aniShow: 'none'  
                            }  
                        });  
                    }, 500);  
var isInTransition = false;  
             //显示侧滑菜单  
            function openMenu() {  
                if (isInTransition) {  
                    return;  
                }  
                if (!showMenu) {  
                    //侧滑菜单处于隐藏状态，则立即显示出来；  
                    isInTransition = true;  
                    menu.setStyle({

                    }); //menu设置透明遮罩防止点击  
                    menu.show('none', 0, function() {  
                        //主窗体开始侧滑并显示遮罩  
                        main.setStyle({  
                            mask: 'rgba(0,0,0,0.4)',  
                            left: '70%',

                        }, 160);  
                        showMenu = true;  
                    });
