我有一个看起来像这样的 json 对象：

{
    "id": "id_1636844335636",
    "title": "Emmy",
    "start": "2021-11-09",
    "end": "2021-11-10",
    "description": "<img class=\"img-fluid\" src=\"data\/uploads\/content_media_6190432d1512a.jpg\" alt=\"\" width=\"196\" height=\"130\" \/>",
    "allDay": true,
    "order": 1
}

读取 json 数据时，出现 js 错误“Uncaught SyntaxError: Unexpected identifier”

当我在描述中替换\"为时'，一切都很好。

// no error when changing to this:
"description": "<img class='img-fluid' src='data\/uploads\/content_media_6190432d1512a.jpg' alt='' width=\"196\" height='130' \/>",

我在 fullcalendar 脚本中使用这些 json。我真的不知道为什么转义字符\"会导致问题。json 中的语法是否以某种方式错误？

顺便说一句：这就是 json 是如何由 php 创建的：

$file = 'data/'.$id.'.json';
$jsonData = json_encode($array, JSON_NUMERIC_CHECK | JSON_PRETTY_PRINT);
file_put_contents($file, $jsonData);

更新：这是读取 json 数据的 Fullcalendar 脚本的一部分：

 events: [
        
            <?php
                        
            $rii = new RecursiveIteratorIterator(new RecursiveDirectoryIterator('data/rooster/')); // read all files from all the years dirs
            $roosterfiles = []; 
            foreach ($rii as $roosterfile) {
                if ($roosterfile->isDir()){ 
                    continue;
                }
                $roosterfiles[] = $roosterfile->getPathname(); 
            }
            
            
            //$roosterfiles = glob('data/rooster/2021/*.json'); // all roosterfiles in events folder
            
            foreach($roosterfiles as $roosterfile) {
                $objs[] = json_decode(file_get_contents($roosterfile), true); // decode to php assoc array              
            }
            
            foreach($objs as $key => $val) {                
            ?>
            {
                // Eventdata
                id: "<?php echo $val['id']; ?>",                            // id               
                groupId: "<?php echo $val['groupId']; ?>",                  // groupId integer only! 
                category: "<?php echo $val['category']; ?>",                // category

                textColor: "<?php echo $val['textColor']; ?>",              // textcolor    
                start: "<?php echo $val['start']; ?>",                      // start  
                end: "<?php echo $val['end']; ?>",                          // end
                description: "<?php echo $val['description']; ?>",          // description
                url: "<?php echo $val['url']; ?>",                          // url
                borderColor: "<?php echo $val['backgroundColor']; ?>",      // optional; same color as background
                allDay: "<?php echo $val['allDay']; ?>",                    // default all day event
                order: "<?php echo $val['order']; ?>",                      // order by category                
            },              
                                
            <?php   
            } // end foreach                 
                
            ?>
