如何以html5格式向提交按钮添加确认对话框？

Question

我正在创建一个应用程序,django我有下一个问题:我有一个带有提交按钮的html表单,但我想显示一个确认对话框来选择Yes或No在处理信息之前.我怎么能这样做？

这是我的表单代码:

<form id="id" method="post" action="/y/b/" enctype="multipart/form-data">

    {% csrf_token %} 

    {{ form.as_p }}

    <input class="btn btn-primary" type="submit" name="submit" value="A" />
</form>

非常感谢!

onsubmit如果您只是想要用户确认,请在您的表单标记中添加属性.

<form id="id"
    method="POST" action="/y/b/"
    enctype="multipart/form-data"
    onsubmit="return confirm('Do you really want to submit the form?');"
>
    <input class="btn btn-primary"
        type="submit" name="submit" value="A"
    />
</form>

编辑: 或尝试下面的代码

<form id="id"
    method="POST" action="/y/b/"
    enctype="multipart/form-data"
>
    <input class="btn btn-primary"
        type="submit" name="submit" value="A"
        onclick="return confirm('Do you really want to submit the form?');"
    />
</form>
