I started digging into the code following the forum https://www.digitalocean.com/community/questions/copy-and-paste-into-console and https://gist.github.com/croepha/7b53f211ae4be3c526c3.

The changes I did are:

  • Support A-Z uppercase characters;
  • The RFB.messages.keyEvent() changed and now requires rfb._sock. So, I simply change it to rfb.sendKey();
  • Remove the prompt and added the sendString() method;

I successfully tested it on:

  • EMBRATEL Cloud Service;
  • Digital Ocean.
  • Vultr;

Usage:

Open the developer tool box and paste the JavaScript above in the "console".

To send a string use:

sendString('string to be typed');

Let me know if it works

@blondie63 Try the CTRL+SHIFT+I shortcut if right-clicking is not available

@katahdin0 Read byjg's comment...

@byjg Worked great for me on Vultr!

I did not watching this gist. Thank you for the information. CTRL+SHIFT+I or F12 could help as well.

Super @byjg 👏
Two small changes:

  • Added pressOnly as pres/release generates echo in my test
  • Added XK_Shift_L constant
// This will open up a prompt for text to send to a console session on digital ocean
//  Useful for long passwords
(function () {
    const XK_Shift_L = 65505; // https://docs.rs/x11-dl/1.0.1/x11_dl/keysym/constant.XK_Shift_L.html      
    window.sendString = function (str, pressOnly) {
        f(str.split(""));
        function f(t) {
            var character = t.shift();
            var i=[];
            var code = character.charCodeAt();
            var needs_shift = character.match(/[A-Z!@#$%^&*()_+{}:\"<>?~|]/);
            if (needs_shift) {
                rfb.sendKey(XK_Shift_L,1);
            }
            rfb.sendKey(code,1);
            !pressOnly && rfb.sendKey(code,0);
            if (needs_shift) {
                rfb.sendKey(XK_Shift_L,0);
            }
            
            if (t.length > 0) {
                setTimeout(function() {f(t);}, 10);
            }
        }
    }
})();

Thank you for your solution , saved my day . Just one small issue , if I try to paste characters like !@#$%^&*()_+ it actually prints 1234567890-= . I was testing on firefox , Ubuntu OS .

Glad that helps you. These characters should be handled by this:

            var needs_shift = character.match(/[A-Z!@#$%^&*()_+{}:\"<>?~|]/);
            if (needs_shift) {
                rfb.sendKey(XK_Shift_L,1);
            }

It means, should "press" SHIFT and the key.

This code doesn't support new lines

Did you try:

sendString("mychars\r\nother chars");  # Maybe your client accepts \r\n as new line.

Did you try:

sendString("mychars\r\nother chars");  # Maybe your client accepts \r\n as new line. 

Yup, tried \r, \n, \r\n.
And even tried rfb.sendKey(13, true). None worked, it feels like noVNC don't accept new lines in this function or something.
