onSend function does not execute it's code when OctoberCMS AJAX calls it

Question

i'm trying to execute some code using the October's Data Attribute API for front-end forms. The onSend function executes simple codes like echo 'something', but doesn't more complex code, like trying to use mpdf plugin. I guess it's related to AJAX reloading the page, but don't know how to solve it.

I tried using data-request from the Data Attribute API, calling the function onSend, but the code on onSend does not execute.

My form header is as follows:

<form class="register-form" method="POST" data-request="onSave">

and my function onSave:

public function onSave(){
$mpdf = new \Mpdf\Mpdf();
$mpdf->WriteHTML('<div style="text-align: center"> Test </div>');
$mpdf->Output();
}

Note that both codes are on a component, and the onSave function executes when i try something just like:

echo 'Test';

您要渲染/流式传输PDF？您是否在浏览器中查看了网络监视器？

我将通过public function onRun()调用来测试您的mpdf代码。确保可以使用。

尝试更新部分内容。 data-request-update="'{{__SELF__::partial}}', '#element'"

除此之外，您可能需要执行整页重定向。我如何流式传输PDF是我有一个使用该https.domain.com/stream/pdf?id=encryptedsomething的route.php。对该路径进行了编程，以在解密id之后在模型中查找特定对象，并将数据显示为PDF。
