AngularJS 指令 描述 $scope.fName 模型变量 (用户名) $scope.lName 模型变量 (用户姓) $scope.passw1 模型变量 (用户密码 1) $scope.passw2 模型变量 (用户密码 2) $scope.users 模型变量 (用户的数组) $scope.edit 当用户点击创建用户时设置为true。 $scope.error 如果 passw1 不等于 passw2 设置为 true $scope.incomplete 如果每个字段都为空(length = 0)设置为 true $scope.editUser 设置模型变量 $scope.watch 监控模型变量 $scope.test 验证模型变量的错误和完整性 有关更多的 Bootstrap 类样式,请阅读我们的 Bootstrap 教程
