How do I Ping in JavaScript?

[morgansolutions]

Hi

I'm new to JavaScript and am still trying to grasp the basics. However, I need to create something which could be quite complex and am beginning to wonder if JavaScript may not be the right language to use for the task.

At work, I find myself pinging all the time - in fact it is quite often the case that I'll have in excess of 30 pings running to different terminals worldwide simultaneously. To make life easier, I'd like to create a script where I can run nermerous pings side by side (rather then opening a new command prompt for each ping!) I'd also like to have some notification once the connection is live, maybe a system bleep for example to grab my attention, and also a display of how long the connection has been alive for (so I can determine whether or not it's worth connecting to the terminal or if it's still booting up!)

Anyway pointers would be gratefully appreciated.

Sorry, no... JS isn't capable of anything like this unless the host
(usually a browser, but not necessarily) provides some interface to do
it.

It is possible to ping a specific image:-

you can only make connections to a server on your own domain.

you can use a synchronous HEAD request to contact your server with just one packet coming back, essentially a beefy ping, and able to be timed as well.

and like philip m said, if you can find an image on the remote server, you can cross domains and verify status by checking the height of the image once it loads.
