Why does $.getJSON() block the browser?

Question

I have a page where I list hardware devices we monitor for customers. Each row displayed also shows the status of the device i.e. whether it\'s running, paused, starting up etc.

Answer 1

It sounds like getJSON is using asynchronous: false as an option to xhr. It kind of suprises me that jquery would use that as a default though, since that is pretty much always a bad idea for the reasons that you are describing.

Don't have the time to look into it more at the moment, but that is the first path I would take.
