B4J Question How to use b4j_senddata ?

[jinyistudio]

I have see b4j_senddata in the b4j_ws.js. How does it work with srvr.AddWebSocket ? I want to send data(json format) to server side.

example : b4j_senddata('{'D1':1,'D2':2}') --> server side, how to programmig ?

function b4j_sendData(data) {
    b4j_ws.send(JSON.stringify({type: "data", data: data}));
}

Why have you omitted the important comment:
//only called as a result of a server request that is waiting for result.
//this method should not be called in any other case.

You can use b4j_raiseEvent to call a server sub.
