If you do the redirect before generating content (the preferred way):

call.respondRedirect("/path", permanent = false)

thanx

It is possible to do redirects also from html content, but not as recommended.

Via html header:

<meta http-equiv="refresh" content="0; url=/path" />

Or via javascript:

<script type="text/javascript">
document.location.href = '/path';
</script>

Ah, okay.

Okay, related, but not really: Instead of redirecting the user, is there a way to update the html some how without reloading? Showing another text input, etc? I guess it’s possible with js/php, but how with ktor?

[Deactivated User]

The same way as PHP: if you want to change the contents dynamically, you would have to use JS

[Deactivated User]

You can use jquery for example

[Hamza]

So no inbuilt library?

I don’t think that’s something related to ktor.
Check examples from here: http://api.jquery.com/jquery.ajax/

You can generate a page in ktor and use jquery to read that page, extract a fragment of it and replace some content of your current page.

If you mean if ktor has a feature to generate that javascript. No, it doesn’t.

i was thinking of something like when you submit a form, it just updates the current page saying “thank you for submitting the form”, but you stay on the page, and it just shows a little input box, so you can fill it out again. but when you click it, it also runs some kotlin code, which i’ve already got working

[Deactivated User]

that’s still javascript

[Deactivated User]

javascript handling the onsubmit event of the form, preventing it from executing the default code

[Hamza]

ah, ok

[Deactivated User]

then you can in that code, add that text, and fetch another page without loading in your main frame

[Deactivated User]

or creating an invisible iframe and setting the target of the frame there

[Deactivated User]

but you would still need to use javascript to change the text

[Hamza]

Ok. Thanks
