Nah, not working

Are you sure you are doing this after getting connected?
If you send a message before connecting then it won't reach server right?
You need to listen to on_connected callback and then subscribe after that you can set mode. If you directly set mode it won't automatically subscribe.

Same code and sending requests by one request in comment and one as code works and now reversing comment not working!

Can you paste your complete code here?

@sujith here is my test code

{
//var message = {"a": "subscribe", "v": [10154498]};
var message = {"a": "mode", "v": ["full", [10154498]]};
ws.send(JSON.stringify(message));
};
ws.onclose = function () {
    setTimeout(function () {
        // Connection has closed so try to reconnect every 10 seconds.
        c(); 
    }, 10*1000);

@gautam_s60 I'm getting ticks if I do:

var message = {"a": "subscribe", "v": [10154498]};
ws.send(JSON.stringify(message));
message = {"a": "mode", "v": ["full", [10154498]]};
ws.send(JSON.stringify(message));

Also, your tick parsing is wrong. You are not considering first two fields in the tick - packet count and packet length. Refer the documentation to understand this in detail.

Or you can use the JS library which has implemented all this along with reconnection mechanisms.

gautam_s60 · May 2018

but why it is not returning data if i put only
message = {"a": "mode", "v": ["full", [10154498]]};
ws.send(JSON.stringify(message));

You can't set mode without subscribing for the data.
