Change source (url) of Server-Sent event

问题

How can I change the source set in declaration of EventSource?

I have tried something like this:

var source = new EventSource("/blahblah.php?path=" + (window.location.pathname));
// Few lines later...
source.url = "/blahblah.php?path=" + url;

But, source.url stays the same...

Is this even possible? Or maybe there are alternative ways to do that?

回答1:

No, it is not possible. A new URL passed to EventSource() creates a new EventSource object.

回答2:

guest271314 suggested me much solutions to this, but for me it would be much better, faster and less complicated to stay with sse.

I changed the source by closing and removing (all are necessary) the source var.

This is how I did it:

source.url = "/blahblah2.php";

source.close();
delete source;

//Redefine source

IMPORTANT: This won't work if you defined source with var! Redefinition should also go without it!
