为 $state 对象提供自定义数据
可以给 $state 对象提供自定义数据（建议使用data属性，以免冲突）
<span>// 基于对象和基于字符串定义 state 的例子</span> <span>var</span> contacts = { name: <span>'contacts'</span>, templateUrl: <span>'contacts.html'</span>, data: { customData1: <span>5</span>, customData2: <span>"blue"</span> } } $stateProvider .state(contacts) .state(<span>'contacts.list'</span>, { templateUrl: <span>'contacts.list.html'</span>, data: { customData1: <span>44</span>, customData2: <span>"red"</span> } })
可以通过下面的方式来访问上面定义的数据：
