Vue submits form to use websocket protocol. The send method has been successful. How to receive the data sent from the background?

< script >
export default {
name:"- sharpindex2",
methods: {

submit: function() {
  this.websocketsend({a:1})
},
threadPoxi: function() { // 
  //
  const agentData = "mymessage";
  //ws
  if (this.websock.readyState === this.websock.OPEN) {
    this.websocketsend(agentData)
  }
  //  300
  else if (this.websock.readyState === this.websock.CONNECTING) {
    let that = this; //this
    setTimeout(function() {
      that.websocketsend(agentData)
    }, 300);
  }
  //  500
  else {
    this.initWebSocket();
    let that = this; //this
    setTimeout(function() {
      that.websocketsend(agentData)
    }, 500);
  }
},
initWebSocket: function() { //weosocket
  const wsuri = "ws://192.168.1.186:9353/websocket";
  this.websock = new WebSocket(wsuri);
  this.websock.onmessage = this.websocketonmessage;
  this.websock.onclose = this.websocketclose;
},
websocketonmessage: function(e) { //

  const redata = JSON.parse(e.data);
  console.log("onmessage=" + redata);
},
websocketsend(agentData) { //
  this.websock.send(agentData, function(data) { console.log(data) });
},
websocketclose: function(e) { //
  console.log("connection closed (" + e.code + ")");
},
loginBuy: function() {},
loginSell: function() {}

},
created () {

this.initWebSocket()

}
