云端打包后pullrefresh不起作用

var subpages = [{  
    url: 'pullrefresh_trans_manage.html',  
    id: 'pullrefresh_trans_manage.html',  
    styles: {  
        top: '120px',  
        bottom: '0px',  
    }  
}];  
var contentWebview = plus.webview.create(subpages[0].url, subpages[0].id, subpages[0].styles);  
plus.webview.currentWebview().append(contentWebview);  
contentWebview.evalJS("mui('#pullrefresh').pullRefresh().scrollTo(0,0,100)");  

//'pullrefresh_trans_manage.html就是初始化pullrefresh  
if(mui) {  
    mui.plusReady(function() {  
        setTimeout(function() {  
            mui('#pullrefresh').pullRefresh().pullupLoading();  
        }, 1000);  

    });  
} else {  
    mui.ready(function() {  
        mui('#pullrefresh').pullRefresh().pullupLoading();  
    });  
}

用HBuilder真机运行可以刷新数据，可是用云端打包之后，pullrefresh根本不起作用，没有看到任何刷新动作，真是醉了。云端打包有何讲究？？
HBulider真机运行效果
