AngularJS1.4.6

1、ng-init会使controller对应的初始化失效

2、有效：ng-show="myForm.myAddress.$error.email"

     无效：ng-show="myAddress.$error.email"

3、 <input type="email" ng-model="name" name="name1">
      <p>{{name}}</p>

      只有当name是合法数据时才会显示{{name}}

4、<select ng-model="selectedName">
            <option value="0">请选择</option>
            <option ng-repeat="x in names" value="{{x.id}}">{{x.name}}</option>
      </select>

      运行时发现没有默认值，必须初始化：$scope.selectedName='0'，或者<select ng-model="selectedName" ng-init="selectedName='0'">

5、<select ng-model="selectedName" ng-init="selectedName=1" ng-options="x.id as x.name for x in names"></select>

     x.id是key，x.name是value
