Send Javascript variable to Arduino Ethernet?

Projects General Guidance
1

For this project, I am not connected to the internet. The webpage is hosted on my Arduino Uno's Ethernet Shield and it's SD card.

Is there a way to send a Javascript variable, which contains a string, to my Arduino?

Clients can send character strings to servers. What have you tried so far?

zoomkat - I would be very interested in hearing a solution to this topic as this is exactly what I am trying to do also. I am trying to host a simple web server on my arduino ethernet, and all it has is a text box input box, and a submit button. I have written html form and javascript in the arduino code to take the text and assign it to a variable. I am trying to pass the javascript variable (i.e. string) to the arduino code so I can use the arduino to turn pins on or off. Any point in the right direction would be much appreciated. :smiley:

The javascript I've seen is normally contained in the web page source code with the data generated passed to the server via a GET request. Do you have the html code that you are working with?
