我的JavaScript函数在php中不起作用 - My JavaScript function doesn't work in the php

My JavaScript function doesn't work in the php

我的JS函数找到的名称正在破坏代码。当我删除它时，JS是有效的。函数中的两个警报都不起作用。这是代码。可能有点困惑，但重要的是JS中的JS功能和警报。

我正在使用记事本++，HTML输出什么都没有。我想查看警报。

<html> 
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <style type="text/css">
        table.Ekim {table-layout:fixed;}
    table.Ekim td{text-align: left; vertical align:top;width:14.2%;height:20%}
</style>
<head>

<body>

<?php
   header('Content-type: text/html; charset=utf-8');

$doc = new DomDocument(); 
$site = 'http://www.etu.edu.tr/?q=tr/takvim'; 
$deneme ="ali";
$olay = array();
$tarih = array();

if (@$doc->loadHTMLFile($site)) {    
$items = $doc->getElementsByTagName('div');     
foreach($items as $item) {
    if ($item->getAttribute("class") == "takvim-olay"){  
            $str = $item->nodeValue;  
array_push($olay,utf8_decode($str));
    }
}
  $items = $doc->getElementsByTagName('div');    
foreach($items as $item) {
    if ($item->getAttribute("class") == "takvim-tarih"){  
            $str = $item->nodeValue;  

array_push($tarih,utf8_decode($str));
        }
    }

问题是

boolean ctrl = true;

这不是有效的JavaScript。可能，你想要

ctrl = true;
