我是新来的html和java脚本。对于我的代码，我一直得到我的功能没有定义，我不知道为什么。我尝试将脚本移动到head标签并在通话之后。我尝试改变函数的名字，以确保它没有被使用。我想我缺少一些小而愚蠢的东西。任何帮助将不胜感激Javascript - 未定义的函数错误
<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;
}
</script>

di后添加=看起来你有语法ê你的'aaa'函数中的错误：var di = document.getElementById（“d”+ i）'。它缺少一个等号。 – Nick而我更喜欢数组文字'[0,0,0,0]'而不是构造函数。 –
学习（然后编码）JavaScript的最重要的部分之一是使用浏览器控制台。 （'console.log'和'console.error'）在整个代码中，这些行将帮助您进行调试。即使你不使用这些，浏览器在遇到问题时仍会抛出错误和警告，以及（通常不是）发生错误的确切行号。您可以通过大多数现代浏览器中的开发人员工具打开控制台（通常键盘快捷键是“Ctrl + Shift + i”）。学习爱上控制台，欢迎来到SO。 – Dellirium
