3.4 angular指令判断两次输入密码是否一致

                    <div class="form-group">                        <label class="col-sm-2 control-label">密码</label>                        <div class="col-sm-6">                            <input type="password" class="form-control"  placeholder="请输入密码" ng-model="data.password" name="password" ng-required="true">                            <span class="glyphicon glyphicon-remove text-danger input-feedback" ng-show="registerForm.password.$dirty && registerForm.password.$invalid"></span>                            <span class="help-block" ng-show="registerForm.password.$dirty&&registerForm.password.$invalid ">                                <span class="text-danger" ng-show="registerForm.password.$error.required">密码是必须要输入的</span>                            </span>                        </div>                    </div>                    <div class="form-group">                        <label class="col-sm-2 control-label">确认密码</label>                        <div class="col-sm-6">                            <input type="password" class="form-control"  placeholder="请再次输入密码" ng-model="data.pwdAgain" name="pwdAgain" ng-required="true">                            <span class="glyphicon glyphicon-remove text-danger input-feedback" ng-show="registerForm.pwdAgain.$dirty && registerForm.pwdAgain.$invalid"></span>                            <span class="help-block" ng-show="registerForm.pwdAgain.$dirty">                                <span class="text-danger" ng-show="registerForm.pwdAgain.$error.required">请再次输入密码</span>                                <span class="text-danger" ng-show="(registerForm.password.$viewValue != registerForm.pwdAgain.$viewValue)">两次密码不一致</span>                            </span>                        </div>                    </div>

4.跳转到其他路由：

  $scope.$on('$stateChangeStart',      function(event, toState, toParams, fromState, fromParams) {          if (!confirm("还没保存草稿，确定要离开此页面")) {              event.preventDefault();          }      })

5：AngularJS系列之select下拉选择第一个选项为空白的解决办法
参考：
http://blog.csdn.net/linzhiqiang0316/article/details/52489668

自己做的实例：
html部分:

    <select class="form-control" ng-model="numSelect">        <option value="">请选择</option>        <option ng-repeat="item in i31data" value="{{item.value}}">{{item.value}}</option>    </select

js数据部分:

    $scope.i31data = [          { id: '1', value: '1' },          { id: '2', value: '2' },          { id: '3', value: '3' },          { id: '4', value: '4' },          { id: '5', value: '5' },          { id: '6', value: '6' },          { id: '7', value: '7' },          { id: '8', value: '8' },          { id: '9', value: '9' }      ];
