Question

我正在学习Python和Flask，我的经验很少，但这是不可能的。与通常的AJAX没有任何问题，但我决定尝试sijax，甚至一个简单的例子都行不通。我确定这是由于错误的连接和初始化，因为我从官方存储库git hub做了git clone，一切正常。

在三个例子中，sijax在单文件应用程序中工作和初始化，我想在蓝图中使用

如果我点击<a href="javascript://"onclick="Sijax.request('say_hi');">Say Hi!</a> 回溯：127.0.0.1 - - [12 / Sep / 2016 14:19:56]＆＃34; POST / HTTP / 1.1＆＃34; 400 -

        g.sijax.register_callback('say_hi', say_hi)
        return g.sijax.process_request()

    return render_template('test/hello.html')

模板hello.html

<!doctype html>

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>

</head>

<body>
    <a href="javascript://" onclick="Sijax.request('say_hi');">Say Hi!</a>
</body>
</html>

Answer 1

原因是没有使用sijax，事实是{{csrf_token（）}}不活跃

有必要这样做：<a href="javascript://" onclick="Sijax.request('say_hi', { data: { csrf_token: '{{ csrf_token() }}' } });">Say Hi!</a>

连接到html文件：

<script type="text/javascript">
    var csrfToken = "{{ csrf_token() }}"
</script>

简单的sijax exapmle不起作用
