在JSON對象上顯示2條件

Question

如何在不同div上顯示報價和新報價條件。請幫我想說明2的條件，我這樣的代碼：

function setup() { 
    output = document.getElementById("output2"); 
    var ws = new WebSocket('wss://www.binary.com/websockets/v3?l=RU'); 

    ws.onopen = function(evt) { 
     ws.send(JSON.stringify({ticks:'R_50'})); 
    } 

    ws.onmessage = function(msg) { 
     var quote = JSON.parse(msg.data).tick.quote; 
     var newquote = quote.substr(-1); 
     log(newquote);//here should be semi-colon 
    } 

} 

function log(info) { 
    //Display information on screen 
    var p = document.createElement("p"); 
    p.innerHTML = info; 
    output.appendChild(p); 
    console.log(info); 
} 

function sendMessage(msg) { 
    ws.send(msg); 
    log("TICKS"); 
    ws.close(); 
} 

window.addEventListener("load", setup, false);

你爲什麼不創建HTML TWI不同div，然後做

HTML

<div id="quote-div"></div> 
<div id="newquote-div"></div> 

JavaScript

// Let id of div be an argument of function 
function log(info, id) { 
      var p = document.getElementById(id); 
      p.innerHTML = info; 
     } 
// and use it like 
var quote = JSON.parse(msg.data).tick.quote; 
var newquote = quote.substr(-1); 
log(quote, "quote-div"); 
log(newquote, "newquote-div");
