Zend framework - how to add CSS and JS only one time in the header without duplication?

在ZF2，我试图加载CSS和JS文件只有一次。

但是当我渲染页面时，它们被加载了两到三次，导致网站非常慢。

在实际页面我有bootstrap.css 2次，style.css 2次，和JS文件也2,3次。

<!doctype html>
<html>
<head>
  <meta charset="utf-8" />
  <?= $this->headTitle(); ?>  
  <?= $this->headMeta(); ?>
  <!-- CSS -->
  <?= $this->headLink()->prependStylesheet('/v2/css/bootstrap.css'); ?>  
  <?= $this->headLink()->prependStylesheet('/v2/css/style.css'); ?>  
  <!-- JS -->
  <?= $this->headScript()->prependFile('/v2/js/jquery-3.1.0.min.js') ?>
  <?= $this->headScript()->prependFile('/v2/js/global.js') ?>
</head>

您在每行上重复对象;删除所有的<?=，代之以一个echo调用。

<head>
  <meta charset="utf-8" />
  <?= $this->headTitle(); ?>  
  <?= $this->headMeta(); ?>
  <!-- CSS -->
  <?php 
    $headLink = $this-headLink();
    $headScript = $this->headScript();
    $headLink->prependStylesheet('/v2/css/bootstrap.css');
    $headLink->prependStylesheet('/v2/css/style.css');
    $headScript->prependFile('/v2/js/jquery-3.1.0.min.js');
    $headScript->prependFile('/v2/js/global.js');
    echo $headLink;
    echo $headScript;
  ?>
</head>

最简单的方法是将链接到，如下所示:

<!doctype html>
<html>
<head>
  <meta charset="utf-8" />
  <?= $this->headTitle(); ?>  
  <?= $this->headMeta(); ?>
  <!-- CSS -->
  <?= $this->headLink()->prependStylesheet('/v2/css/bootstrap.css')
        ->prependStylesheet('/v2/css/style.css'); ?>  
  <!-- JS -->
  <?= $this->headScript()->prependFile('/v2/js/jquery-3.1.0.min.js')
        ->prependFile('/v2/js/global.js'); ?>
</head>
