I have an exe file which can detect F6 key whenever i press in browser. But i want to do this task programatically in javascript. I have tried different methods from stackoverflow but none of them is detectable by exe file. But when i press F6 key manually then exe file detects.
These are the methods i have tried but none of them worked for me:
Javascript - trigger specific keyboard keys
Is it possible to simulate key press events programmatically?
etc.
After this automatic trigger, exe file return F7 key and i have to detect it in browser using javascript.
This is done with nodejs by using https://www.npmjs.com/package/node-key-sender
node-key-sender is good to trigger keyboard keys automatically, see the code below
const http = require('http');
var ks = require('node-key-sender');
const requestListener = function (req, res) {
res.writeHead(200);
res.end('Server is running under 9999 port');
ks.sendKey('F6');
}
const server = http.createServer(requestListener);
server.listen(9999);
In response, i can detect any key trigger by https://www.npmjs.com/package/iohook
Finally my code is:
const http = require('http');
var ks = require('node-key-sender');
const ioHook = require('iohook');
const requestListener = function (req, res) {
res.writeHead(200);
res.end('Server is running under 9999 port');
ioHook.on("keydown", event => {
console.log(event);
// {keychar: 'f', keycode: 19, rawcode: 15, type: 'keypress'}
});
ioHook.start();
ks.sendKey('F6');
}
const server = http.createServer(requestListener);
server.listen(9999);
