如何使用包含 javascript django 的 html 模板发送 email？

Question

I have an email template that is rendering certain datetime strings from django. I would like to render this time based on the user's timezone. To solve this I have opted to use momentjs however once, it seems the javascript in the template is not run and anything wrapped in javascript doesn't appear in the email. Based from this answer https://stackoverflow.com/a/42056995/8513875 email clients don't include external css, I assume it's the same issue with javascript, how would I go about making this recognized.

Answer 1

To expand on what @IainShelvington stated, and answer...

@oma0256... how I can determine a user's timezone...

... here's how to obtain the timezone offset via JavaScript (in browser) prior to generating the email...

const timezone = (new Date).getTimezoneOffset() / 60;

... note again, this will not run within an email, but instead should be used when generating the email from whatever template the service is using.

And regarding the second part of the question...

@oma0256... for instance based on their email?

... if you're fortunate that information will be within the email headers, however, such things (much like any other client-side supplied data) cannot be trusted.
