如何以html5格式向提交按钮添加确认对话框？

问题描述

我正在 django 中创建一个应用程序，我有下一个问题：我在html中有一个带有提交按钮的表单，但我想显示一个确认对话框在处理信息之前，请选择是或否。我怎么能这样做？

I am creating an application in django and I have the next problem: I have a form in html with a submit button, but I want to show a confirmation dialog to select Yes or No before processing the information. How could I do it?

这是我的表格代码：

<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>

非常感谢你！

推荐答案

如果您只是想要用户确认，请在表格标签中设置 onsubmit 属性。

Have onsubmit attribute in your form tag like this if you just want a confirmation from user.

<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>

编辑或尝试以下代码

<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>
