下記のコードのデジタル時計をリアルタイムで表示させるには、文字を更新する処理などが  
必要かと思われますが、どのように書き変えたらいいのか分かりません。var ti～var msgまでを  
どこに記入し、その他必要な処理があればご教示ください。

デジタル時計をリアルタイムで表示させたい(別コード)


drag = function(){}の内容を以下のように書き換えます

[code]

    drag = function(){ // makes the resistance
    
    var ti = new Date;
    
    var Hour = ti.getHours();
    var Min = ti.getMinutes();
    var Sec = ti.getSeconds();
    
    if(Hour <= 9) 
    {
     Hour = "\u0020\u0020" + Hour; 
    }
    if(Min <= 9)
    {
     Min = "0" + Min; 
    }
    if(Sec <= 9)
    {
     Sec =  "0" +  Sec; 
    }
    
    var msg = Hour + ":" + Min + ":" + Sec ;
    
    msg = msg.split('');
    var n = msg.length - 1;
    
    for (var d, i = n; i > -1; --i)
    {
        var elm = document.getElementById('iemsg' + i);
        elm.innerHTML = msg[i];
    };
    
     y[0] = Y[0] += (ymouse - Y[0]) * speed;
     x[0] = X[0] += (xmouse - 20 - X[0]) * speed;
     for (var i = n; i > 0; --i){
      y[i] = Y[i] += (y[i-1] - Y[i]) * speed;
      x[i] = X[i] += (x[i-1] - X[i]) * speed;
     };
     makecircle();
    }
    
[/code]

各文字はid「iemsg+連番」を持つdiv要素で絶対位置配置されているようです。  
そのdivの要素の中身のinnnerHTMLプロパティを毎回書き換えてあげることで希望の動きになります。  
いかがでしょうか？
