<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-status-bar-style" content="black">
<style>
</style>
<script src="vue.js"></script>
<script>
window.οnlοad=function(){
new Vue({
el:'#box',
data:{
arr:['apple','banana','orange','pear']
}
});
};
</script>
</head>
<body>
<div id="box">
