Angius•8/31/23, 10:39 PM

Why would the URL change?

AAngius Why would the URL change?

OpcodeOP•8/31/23, 10:44 PM

there is no url redirection in the controller when i test

A

Angius•8/31/23, 10:46 PM

XHR

XHR

XHR

XHR

A

Angius•8/31/23, 10:47 PM

So, uh, I haven't used XHR since the early 2000s, do you... get the data returned from the request anywhere?

A

Angius•8/31/23, 10:47 PM

Because, yeah, the API controller redirects to another one

A

Angius•8/31/23, 10:47 PM

But that won't reload the page or anything like that

AAngius But that won't reload the page or anything like that

O

OpcodeOP•8/31/23, 10:47 PM

doesn't have to be XHR

A

Angius•8/31/23, 10:49 PM

I mean, XHR or not, just hitting up a controller that redirects somewhere will have no effect on your frontend

O

OpcodeOP•8/31/23, 10:50 PM

Basically I'm trying to do server side redirect or change to another view

AAngius I mean, XHR or not, just hitting up a controller that redirects somewhere will h...

O

OpcodeOP•8/31/23, 10:50 PM

Oh wut

O

OpcodeOP•8/31/23, 10:50 PM

Maybe I don't understand how this stuff works

A

Angius•8/31/23, 10:50 PM

Possibly

O

OpcodeOP•8/31/23, 10:51 PM

So how does return view work then

A

Angius•8/31/23, 10:51 PM

If everything is rendered server-side, then yes, redirecting to a different controller will actually navigate to that different controller

A

Angius•8/31/23, 10:51 PM

But when you call a controller from Javascript, it can be redirecting 172 times

A

Angius•8/31/23, 10:51 PM

And the JS code will follow, yeah

A

Angius•8/31/23, 10:51 PM

But the page showed in the browser will not

O

OpcodeOP•8/31/23, 10:51 PM

Ah so do the redirection in controller and uh js also?

A

Angius•8/31/23, 10:51 PM

JS is specifically used to avoid having to reload the page

O

OpcodeOP•8/31/23, 10:52 PM

Oh

A

Angius•8/31/23, 10:53 PM

As a side note, yeah,

XHR

XHR

XHR

XHR is a relic of the past

A

Angius•8/31/23, 10:53 PM

Use

fetch

fetch

fetch

fetch unless you have a gun to your head

O

OpcodeOP•8/31/23, 10:53 PM

Lol

O

OpcodeOP•8/31/23, 10:53 PM

I tried xhr for synchronus

O

OpcodeOP•8/31/23, 10:53 PM

What's better

O

OpcodeOP•8/31/23, 10:53 PM

Asynchronus js or synchronous js

A

Angius•8/31/23, 10:54 PM

If something can be done asynchronously it's probably for good reason

O

OpcodeOP•8/31/23, 10:55 PM

So it's not needed?

A

Angius•8/31/23, 10:55 PM

What's not needed?

A

Angius•8/31/23, 10:56 PM

Asynchronous code?

A

Angius•8/31/23, 10:56 PM

It probably is needed

A

Angius•8/31/23, 10:56 PM

Going out of your way to use decades-old technology just to force something to be synchronous? Unnecessary and outright detrimental

O

OpcodeOP•8/31/23, 10:57 PM

Oh lol

O

OpcodeOP•8/31/23, 10:57 PM

But also what I don't understand is

O

OpcodeOP•8/31/23, 10:57 PM

If client is doing post req to server

O

OpcodeOP•8/31/23, 10:57 PM

And server is returning viee

O

OpcodeOP•8/31/23, 10:57 PM

How come the client view doesn't update

A

Angius•8/31/23, 10:57 PM

Because it's the JS code that runs the request and receives the response

A

Angius•8/31/23, 10:57 PM

Not the browser

A

Angius•8/31/23, 10:58 PM

You can think of it like the Javascript code opening a hidden browser window in the background

AAngius Because it's the JS code that runs the request and receives the response

O

OpcodeOP•8/31/23, 11:05 PM

Not sure what that really means

O

OpcodeOP•8/31/23, 11:05 PM

You're saying it's the client doing it?

A

Angius•8/31/23, 11:05 PM

Yes

A

Angius•8/31/23, 11:05 PM

Javascript makes requests in its own little world

A

Angius•8/31/23, 11:05 PM

And gets them in their own little world
