这太令人沮丧了。我参加了W2school教程,其中提供了点点滴滴,但它没有回答如何将它们放在一起。我以为我明白了,但是当我把它付诸实践时,什么都没有。 Firebug告诉我inputEmp()没有定义,但很明显在.js文件中定义。有人可以告诉我我遗漏了哪些细节?首先感谢Html,然后是.js文件。

是的,你忘了在return语句之前关闭{while循环的括号{。并且报价未在条件下关闭。
试试这个
function inputEmp() {
var inName = "";
var loopCt = 0
var tArray = new Array();
while (inName != "-1"} {
prompt inName = prompt("Please enter your name (enter -1 to finish)","Employee Name");
if (inName == "-1") { break; }
if (inName==null || inName=="")
{
alert("Blank names are not allowed. To exit enter '-1'.");
}
else
tArray[loopCt++] = inName;
{
}
}
return tArray;
}

您的代码中存在很多问题:
var loopCt = 0
应该如下var loopCt = 0;
while (inName != "-1}
应该如下while (inName != "-1)
prompt inName = prompt...
应该如下inName = prompt...
else语句
下有一个空的{ }
这是一个显示更正代码的jsfiddle。
