ionic的标题是bar-header，副标题是bar-subheader
2、实现源码
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
<title>ionic之副标题bar-subheader</title>
<link rel="stylesheet" href="../css/ionic.css" />
<script type="text/javascript" src="../js/ionic.bundle.js" ></script>
<script>
var app = angular.module("subheaderApp",["ionic"]);
app.controller("subheaderController",function($scope){
$scope.header = "标题";
$scope.subheader = "副标题";
});
</script>
</head>
<body ng-app="subheaderApp" ng-controller="subheaderController">
<p class="bar bar-header bar-assertive">
<label class="title">{{header}}</label>
</p>
<p class="bar bar-subheader bar-balanced">
<label class="title">{{subheader}}</label>
</p>
</body>
</html>3、实现结果
