Question

我是PHP和PHTML的新手，我如何在PHTML中实现JavaScript？这是我试图将其实现的文件，（viewer.phtml）

    <?php
    if ($type == "jpeg") {
        $stype = "jpg";
    } else {
        $stype = $type;
    }
?>
<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title><?php echo APP_NAME . " - $file.$stype"; ?></title>
        <link rel="stylesheet" href="/site/images/assets/css/style.css">
    </head>

    <body>
        <h1><?php echo "$file.$type"; ?></h1>

        <div class="container">
            <img src="/images/<?php echo "$type/$file.$stype"; ?>" alt="<?php echo "$file.$stype"; ?>">
        </div>

        <?php
            $time = microtime();
            $time = explode(' ', $time);
            $time = $time[1] + $time[0];
            $finish = $time;
            $total_time = round(($finish - $start), 4);
        ?>


    </body>
</html>

Answer 1

添加脚本使用脚本标记。将它注入头部标签内，这样你的头部可能看起来像这样

     <head>
        <meta charset="UTF-8">
        <title><?php echo APP_NAME . " - $file.$stype"; ?></title>
        <link rel="stylesheet" href="/site/images/assets/css/style.css">
        <script>
        //you Javascript code here
        </script>
    </head>

或

          <head>
            <meta charset="UTF-8">
            <title><?php echo APP_NAME . " - $file.$stype"; ?></title>
            <link rel="stylesheet" href="/site/images/assets/css/style.css">
           <script type="text/javascript" src="your_js_file_location_here"></script>
        </head>

希望这会对你有所帮助

可以像添加HTML一样添加JavaScript。您可以在PHP标记之外添加它或者您可以使用echo输出您的javascript文本。

示例1：

<?php 
    //my PHP
?>
<html>
  <head>
    <script>alert('hello');</script>
 </head>
 <body>
 </body>
 </html>

示例2

     <html>
  <head>
    <script><?php echo "alert('hello');" ?></script>
 </head>
 <body>
 </body>
 </html>

请注意，一旦将页面或文本发送到浏览器，javascript就无法直接访问PHP变量，而无需通过ajax回调服务器。

实施例

<?php 

  $message="hello";
?>
<html>
 <head>

  <script>
     //this won't work right
     alert('<?php $message ?>');</script>

  <script>
    //this will alert the value of $message at the time echo was called
    alert('<?php echo $message ?>');</script>
 </head>
<body>
</body>
</html>
<?php

  //!!! This won't matter to the javascript alerts, even though its PHP  value has changed. 
  $message='goodbye';

?>
