如何只将crossorigin添加到以下＆lt; script＆gt; 标记中？

＆＃xA;＆＃xA;

目标是仅添加crossorigin而不添加匿名或use-credentials属性。

＆＃xA;＆＃xA;

当前输出：

＆＃xA;＆＃xA;

 ＆lt; li＆gt;＆lt; div id =“somevalue”＆gt; ＆lt; script type =“text / javascript”async src =“some-source”＆gt;＆lt; / script＆gt;＆lt; / div＆gt;＆lt; / li＆gt;＆＃xA;

＆＃xA ;＆＃xA;

所需的输出：

＆＃xA;＆＃xA;

 ＆lt; li＆gt;＆lt; div id =“somevalue”＆gt;＆lt; script type =“text / javascript“crossorigin async src =”some-source“＆gt;＆lt; / script＆gt;＆lt; / div＆gt;＆lt; / li＆gt;＆＃xA;

＆＃xA;＆＃xA; < p>

 （function（）{＆＃xD;＆＃xA; var scriptTag = document.createElement（'script'）;＆＃xD;＆＃xA; scriptTag.type =“text / javascript”;＆＃xD;＆＃xA; scriptTag.async = true;＆＃xD;＆＃xA; scriptTag.src =“some-source”;＆＃xD;＆＃xA;＆＃xD;＆＃xA; var divTag = document.createElement（'div'）;＆＃xD;＆＃xA; divTag.id = 'somevalue';＆＃xD;＆＃xA; divTag.append（scriptTag）;＆＃xD;＆＃xA;＆＃xD;＆＃xA; va r liTag = document.createElement（'li'）;＆＃xD;＆＃xA; liTag.append（divTag）;＆＃的xD;＆＃XA; ＆＃的xD;＆＃XA; var ulList = document.getElementById（'footer-menu'）;＆＃xD;＆＃xA; ulList.append（liTag）;＆＃xD;＆＃xA;}）（）;

 ＆lt; script src =”https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js“＆gt;＆lt; / script＆gt;＆＃xD; ＆＃xA;＆＃xD;＆＃xA;＆lt; ul class =“menu”id =“footer-menu”＆gt;＆＃xD;＆＃xA;＆lt; li＆gt; 1＆lt; / li＆gt;＆＃xD; ＆＃XA;＆LT;李→2＆LT; /立GT;＆＃的xD;＆＃XA;＆LT;李→3＆LT; /立GT;＆＃的xD;＆＃XA;＆LT;李→4＆LT; /立GT;＆＃的xD ;＆＃XA;＆LT; / UL＆GT;

只需使用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);
})();

顺便说一下，crossorigin属性并不是空的：https://developer.mozilla.org/en-US/docs/Web/HTML/CORS_settings_attributes
