Change the frame URL

[juanpmarin]

Hi
Is it possible to change the frame url ? and if it is, how is the handling of the onload

@juanpmarin What's the use case that you're thinking about?

—Thanks

@yowainwright How is going ?
I want to dynamically change the frame URL beign able to don't loose the communication

@juanpmarin hey! Thanks for your response. Your insights are appreciated.

Here's my initial response:

Dynamically changing the child (<iframe>'s src) is not supported by Postmate. Postmate uses postmessage and soon messageChannels. Both APIs expect a secure handshake between a parent (a webpage) and a child (an <iframe>).

What are your thoughts? Would query params work? Have you tried?

[juanpmarin]

Query params would not work because we have different apps on different hosts and we want to change dynamically between pages

[yowainwright]

@juanpmarin thanks for that insight.

A good use-case of Postmate is securely sharing information between a webpage and an iframe—like a form with personal information.

To me, this means that allowing information to be shared between a parent webpage and an iframe. Different/changing sources is a not a best practice for that. That issue can be bypassed and security can be maintained is by setting up a secure host for iframe src's and then whitelisting that host to allow for cross origin sharing. ...That's my abstract consideration.

@yowainwright sorry, I don't got what you suggestion means, you say that we should have an unique host that routes to the others apps ?

Sorry, I was describing my companies own use case.

To accomplish that your initial goal (as I understand it), the ur could be changed with JS or a new Postmate instance can be created.
