是因为JS内不能embedPHP吗？但是好像也不是这个原因。麻烦大家帮忙看看了
没试过，估计是不支持。
建议放在外面，文件后缀名要为.php才可以.
你的服务器端的函数，就没有输出到客户端，one函数当然没有就报错了。楼主要搞清楚客户端和服务器端来

<script>
function one(){
alert('function one')
}
<?php
function one() {
if (!file_exists("error_handling.txt")){
die("The File Does Not Exist!");
}else{
$file = fopen("error_handling.txt","r");
};
