howto execute a jquery script inside a Processing program

in General Discussion • Other • 3 months ago

Hi all,

I've written a test program in Processing 2.0 to pick values from a webserver and share them with an industrial PLC. This works fine!

Anyway I've been requested to write some values to this webserver and I've been told to use a jquery command to send it.

Can I put jquery scripts inside Processing code and send them with a Client.write command? What do you suggest?

Does anyone recommend me something to test jquery scripts? I would try this option plus WireShark to sniff sockets and find out their strings.

Thanks in advance!

Are you using Java based Processing or Processing JS?

If you're using Java based Processing I don't think jQuery will do it for you. jQuery is a client side scripting language used to manipulate the Document Object Model in a web browser. It is capable of sending AJAX requests to write and receive data from a web server but again, you have to be making the request in the context of a browser (actual or virtual). Sending some jQuery commands "over the wire" won't mean anything to the server.

The simplest way to save data to a web server will be in the form of a query string in conjunction with loadStrings().

If you want to do it through Client.write, then you have to program your server to interpret your commands and that differs from one programming language to another. Which language are you using server side?

Hi,

I'm using Java based Processing. Unfortunatelly I haven't too much information regarding to the server side.

I'll try to get the socket contents and try the Client.write command.

Do you know any jquery simulator to send jquery commands? I would send them to the webserver and then I could sniff their sockets with WireShark.

Thanks!

Sure.

You can use any of the ones listed here:

http://stackoverflow.com/questions/3358234/is-there-any-jquery-simulators-where-i-can-practice-usage-of-selectors

Notice that all of the options listed are browser based. This is because jQuery is a *client side* scripting language. It works in a web browser to manipulate elements in the Document Object Model. So for example, suppose you have the following html element:

<div id="myElement">This is my element!</div>

you could use the following jQuery command to put a red boarder around it:

$("#myElement").css("boarder", "3px solid red");

Therefore, you can use jQuery to communicate with your Processing app *from* a web browser, but I highly doubt you'll be able to use your Processing app to send a jQuery command *to* your server.

Do keep us posted though! I'm happy to be wrong.

" I'm using Java based Processing"
Then I was wrong to move it to Processing with Other Languages, but using jQuery in a Java program doesn't make much sense. Don't take too seriously this advice...

" I've been requested to write some values to this webserver"
How? What does the server expect? SOAP? REST? Something else?

It seems REST, but I'm not sure of this point.

Why? What may you suggest?

It depends on what you need to send to / get from this server.
