我有这个 javascript，我收到错误“预期功能”。我看不出我的 javascript 有什么问题。请帮忙。谢谢。
function checkrewardname()
{
var my=document.getElementById("Rname");
var con=my.value;
var mine=document.getElementById("forref").value.split('\n');
if (con == "")
{
alert("Enter a Reward Name.");
}
else
{
var i=0;
while(i<=mine.length)
{
if (mine(i) == con)//error here
{
alert("Duplicate reward. Please enter a new reward.");
}
else
{
document.getElementById("validate").click();
alert("The reward has been saved.");
}
i++;
}
}

mineis an array but you are calling it as if it were a function. Use mine[i]rather than mine(i)and you'll access the array by index rather than generating an error. (Just a note; most C-style languages use [and ]for array access and reserve (and )for function invocation).
mine是一个数组，但您将其称为函数。使用mine[i]而不是mine(i)，您将通过索引访问数组而不是产生错误。（请注意；大多数 C 风格的语言使用[和]用于数组访问和保留(以及)用于函数调用）。

You also have while(i<=mine.length)
你还有 while(i<=mine.length)
shouldn't it be while(i < mine.length)
不应该是 while(i < mine.length)
