如何将跨域添加到< script>标签? [英] How to add just crossorigin to <script> tag?

问题描述

如何仅将交叉源添加到以下<script>标记?

How can I add just crossorigin to the following <script> tag?

目标是仅添加交叉源，而不添加匿名或使用凭据属性.

The goal is to only add the crossorigin and not added the anonymous or use-credentials attributes.

当前输出:

<li><div id="somevalue"><script type="text/javascript" async src="some-source"></script></div></li>

所需的输出:

<li><div id="somevalue"><script type="text/javascript" crossorigin async src="some-source"></script></div></li>

(function() {
  var scriptTag = document.createElement('script');
  scriptTag.type="text/javascript";
  scriptTag.async=true;
  scriptTag.src="some-source";
  
  var divTag = document.createElement('div');
  divTag.id='somevalue';
  divTag.append(scriptTag);
  
  var liTag = document.createElement('li');
  liTag.append(divTag);
  
  var ulList = document.getElementById('footer-menu');
  ulList.append(liTag);
})();

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<ul class="menu" id="footer-menu">
<li>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
</ul>

推荐答案

只需使用setAttribute即可:

Simply use setAttribute :

(function() {
  var scriptTag = document.createElement('script');
  scriptTag.type="text/javascript"
  scriptTag.async=true
  scriptTag.setAttribute('crossorigin','anonymous')
  scriptTag.src="some-source";

  console.log(scriptTag);
})();

顺便说一句，crossorigin属性并不意味着是空的: https://developer.mozilla.org/zh-CN/docs/Web/HTML/CORS_settings_attributes

By the way, crossorigin attribute is not meant to be empty : https://developer.mozilla.org/en-US/docs/Web/HTML/CORS_settings_attributes
