我是新來的html和java腳本。對於我的代碼，我一直得到我的功能沒有定義，我不知道爲什麼。我嘗試將腳本移動到head標籤並在通話之後。我嘗試改變函數的名字，以確保它沒有被使用。我想我缺少一些小而愚蠢的東西。任何幫助將不勝感激Javascript - 未定義的函數錯誤
<html>
<script type= "text/javascript" >
var d = new Array(0,0,0,0,0);
function aaa()
{ alert("hello");
for (var i = 0; i<5; i++){
var da = Math.floor(Math.random()*6) +1;
var di document.getElementById("d" + i);
di.src = "pix/dice" + d + ".gif";
}
}
function newGame(){
}
function click1() {
var total = 0;
for (var i = 0; i <5; i++){
if (d[i] == 1) total +=1;}
var loco = document.getElementById("s1");
loco.innerHTML = total;
}

di後添加=看起來你有語法ê你的'aaa'函數中的錯誤：var di = document.getElementById（「d」+ i）'。它缺少一個等號。 – Nick而我更喜歡數組文字'[0,0,0,0]'而不是構造函數。 –
學習（然後編碼）JavaScript的最重要的部分之一是使用瀏覽器控制檯。 （'console.log'和'console.error'）在整個代碼中，這些行將幫助您進行調試。即使你不使用這些，瀏覽器在遇到問題時仍會拋出錯誤和警告，以及（通常不是）發生錯誤的確切行號。您可以通過大多數現代瀏覽器中的開發人員工具打開控制檯（通常鍵盤快捷鍵是「Ctrl + Shift + i」）。學習愛上控制檯，歡迎來到SO。 – Dellirium
