自定义事件传参问题

main.html 向show.html 页面通过自定义事件传递参数

main.html

mui.each(data,function(i,n){  
                        var livelist = document.getElementById("livelist");  
                        var li  = document.createElement("li");  
                        var a   = document.createElement("a");  
                        var img = document.createElement("img");  
                        var div = document.createElement("div");  
                        var span= document.createElement("span");  
                        var span = document.createElement("span");  

                        a.setAttribute('href','show.html');  
                        a.setAttribute('id',n.id);  
                        //mui.alert(n.id);  
                        img.setAttribute('class','mui-media-object');  
                        img.setAttribute('src',n.livePic ? n.livePic : 'images/logo.png');  

                        div.setAttribute('class','mui-media-body');  
                        div.setAttribute('style','text-align: left; position:relative;');  
                        span.setAttribute('style',' position:absolute; left:3px;');  
                        span.innerText = n.name;  
                        //span.innerText = n.name;  

                        li.className = 'mui-table-view-cell mui-media mui-col-xs-6';  
                        li.appendChild(a);  
                        a.appendChild(img);  
                        a.appendChild(div);  
                        div.appendChild(span);  
                        livelist.appendChild(li);  

                        //open show.html  
                        var liveid = n.id;  
                        live = document.getElementById(liveid);  
                        live.addEventListener('tap','a',function(e){  

                            mui.fire(show,'liveID',{id:liveid});  
                            mui.openWindow({  
                                id:'show',  
                                url:'show.html'  
                            });  
                        });  
                    });

show.html

mui.plusReady(function() {  

        window.addEventListener('liveID',function(event){  
            var liveid = event.detail.id;  
            mui.alert(liveid);  
        });  
    });  

能不能怎样写，如果不能的话该怎么修改
