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

I have never had problems with $.getJSON(). It is asynchronous as far as I know. What is probably happenning is a javascript error, since you're trying to do:

$('div[data-deviceid="' + deviceId + '"]').text(response);

I'm guessing there is an error here because response is a javascript object or array, not a string. What you should do is text(response.desiredProperty) or text(response[index]) according to the type of object response is.

Since javascript errors sometimes make our browsers behave unexpectedly, this MIGHT (only might) me your problem.
