Mui去掉滚动条：

/////////去掉滚动条
mui.plusReady(function(){
plus.webview.currentWebview().setStyle({
scrollIndicator:'none',
softinputMode: "adjustResize"
});
})

让文字逐渐出现：

window.onload=function(){

  var story = document.getElementById('sto');

  var s = document.getElementById('show');

  var a = story.innerHTML.slice("");

  var i = 0;

  timer=setInterval(function(){

    s.innerHTML=story.innerHTML.substring(0,i)

    i++;

    if(s.innerHTML==story.innerHTML){clearInterval(timer);};

  },500);

}

<p id="sto" style="display:none;">从前有座山，山里有座庙，庙里有个老和尚跟老尼姑，有一天....</p>

<p id="show"></p>
