的JavaScript無法打印/陣列

我一直運行到我爲什麼這不會打印JavaScript代碼的錯誤..的JavaScript無法打印/陣列

有人可以一種證明閱讀並告訴我什麼，我做錯了什麼？

我會發布HTML，但我只是將腳本導入到.html文件中的html和樣板中的這種動作。

// JavaScript Document 
 
//var $ = function (id){ 
 
//return document.getElementById(id); 
 
// hooty hoo 
 

 
var money = [0,0,0,0,0,0,0,0,0]; 
 
var newEntry; 
 
var out; 
 

 

 
//1 
 
var $ = function(id) { 
 
return document.getElementById(id); 
 
}; 
 

 
window.onload =function() 
 
{ 
 

 
var button = document.getElementById("Calculate"); 
 
button.addEventListener("click", calc, false); 
 
newEntry = document.getElementById("inputVal").value; 
 
out = document.getElementById("output"); 
 

 

 
}; 
 

 

 
//2 
 
var calc = function() 
 
{ 
 
var result = 200 + (parseFloat(.09 * newEntry)); 
 
//result.mathfloor(result/100); 
 
result.toFixed(); 
 
//var answer = parseInt(document.getElementById("inputVal").value); 
 
if(result<0){ 
 
return; 
 
} 
 
    
 

 
    
 
if(result >= 200 && result<=299) 
 
++money[0]; 
 
if(result >= 300 && result<=399) 
 
++money[1]; 
 
if(result >= 400 && result<=499) 
 
++money[2]; 
 
if(result >=500 && result<=599) 
 
++money[3]; 
 
if(result >=600 && result<=699) 
 
++money[4]; 
 
if(result >= 700 && result<=799)

++money[6]; 
 
if(result >= 900 && result<=999) 
 
++money[7]; 
 
if(result >= 1000) 
 
++money[8]; 
 

 
Display(); 
 
document.getElementById("inputVal").value = "0"; 
 

 
    
 
    
 
    
 
    //3 
 
var Display = function(){ 
 
$("output").value = "gross salary pay/n"+

}; 
 
    
 
    
 
    
 
window.addEventListener("load",calc,false); \t \t \t

爲t這裏有一個實際的錯誤說了什麼，或者是一個錯誤，因爲你不知道爲什麼它沒有做你認爲應該做的事情？ –

我不明白爲什麼它不打印..像它的空白;我會張貼HTML也 – steven

你可以將它轉換成jsfiddle或堆棧的片段？（點擊第二列左邊的第五個按鈕， –

您需要在HTML添加id="output"，因爲你正在使用$("output").value它調用函數

var $ = function(id) { 
     return document.getElementById(id); 
};

// JavaScript Document 
 
//var $ = function (id){ 
 
//return document.getElementById(id); 
 
// hooty hoo 
 

 
var money = [0, 0, 0, 0, 0, 0, 0, 0, 0]; 
 
var newEntry; 
 
var out; 
 

 

 
//1 
 
var $ = function(id) { 
 
    return document.getElementById(id); 
 
}; 
 

 
window.onload = function() { 
 

 
    var button = document.getElementById("Calculate"); 
 
    button.addEventListener("click", calc, false); 
 
    newEntry = document.getElementById("inputVal").value; 
 
    out = document.getElementById("output"); 
 

 

 
}; 
 

 

 
//2 
 
var calc = function() { 
 
    var result = 200 + (parseFloat(.09 * newEntry)); 
 
    //result.mathfloor(result/100); 
 
    result.toFixed(); 
 
    //var answer = parseInt(document.getElementById("inputVal").value); 
 
    if (result < 0) { 
 
    return; 
 
    } 
 

 

 

 
    if (result >= 200 && result <= 299) 
 
    ++money[0]; 
 
    if (result >= 300 && result <= 399) 
 
    ++money[1]; 
 
    if (result >= 400 && result <= 499) 
 
    ++money[2]; 
 
    if (result >= 500 && result <= 599) 
 
    ++money[3]; 
 
    if (result >= 600 && result <= 699) 
 
    ++money[4]; 
 
    if (result >= 700 && result <= 799) 
 
    ++money[5]; 
 
    if (result >= 800 && result <= 899) 
 
    ++money[6]; 
 
    if (result >= 900 && result <= 999) 
 
    ++money[7]; 
 
    if (result >= 1000) 
 
    ++money[8];
