AngularJS 和 W3.CSS

您可以轻松地将 w3.css 样式表与 AngularJS 一起使用。本章演示了如何进行。

W3.CSS

要将 W3.CSS 包含在 AngularJS 应用程序中，请将以下行添加到文档的头部：

如果您想学习 W3.CSS，请访问我们的W3.CSS教程。

下面是一个完整的 HTML 示例，其中解释了所有 AngularJS 指令和 W3.CSS 类。

    } else {
    $scope.edit = false;

}
};

$scope.$watch('passw1',function() {$scope.test();});
$scope.$watch('passw2',function() {$scope.test();});
$scope.$watch('fName', function() {$scope.test();});

}
$scope.incomplete = false;
