php - 在 PHP 中导入 Javascript

Question

我有以下 HTML 和 Javascript:

<noscript>
    <div id="player">
    <h2>Warning! You should enable your JavaScript!</h2>
    </div>
</noscript>
<script type="text/javascript">
    var videoSource="<?php echo $fileName;?>";
    createPlayer(videoSource);
</script>

我需要在 if 中导入此代码块:

<?php
 if($media[$id] != null){
        $video = $media[$id];
        $fileName = "folder/".$video;
       //Here
    }else{
        echo("Error !");
    }
?>

Answer 1

您可以轻松地关闭 php 标签，插入 html 代码，然后重新打开 php 标签，就像这样:

<?php
if($media[$id] != null){
    $video = $media[$id];
    $fileName = "folder/".$video;
?>
<noscript>
    <div id="player">
        <h2>Warning! You should enable your JavaScript!</h2>
    </div>
</noscript>
<script type="text/javascript">
    var videoSource="<?php echo $fileName;?>";
    createPlayer(videoSource);
</script>
<?php
    }else{
        echo("Error !");
    }
?>
