w3data.jsを使用して外部のDIVを削除したい

Question

HTMLをHTML出力レンダリングに追加するのはDIVにありますが、我々は

<div class="test" w3-include-html="template_build/header/header-classic.html"></div> 

を、次のようなものを追加しました。しかし、出力がレンダリングする場合

<div class="test">MY INCLUDED CONTENT</div> 

ことinclduedた私はw3data.jsにレンダリング処理上のdivのクラス=「test」を削除したいです。

誰かが私を助けることができますか？

Answer 1

スニペット1は、特定の要素から任意の属性を削除する単純な機能を備えています。スニペット2は126で、余分なラインを持つw3data.jsです：

elmnt.removeAttribute("class"); 

あなたはどちらか一方が

SNIPPET 1

removeAttr(".test", "class"); 
 

 
function removeAttr(target, attribute) { 
 
    var target = document.querySelector(target); 
 
    target.removeAttribute(attribute); 
 
}

.test { color:red }

<div class="test">THIS CONTENT SHOULD BE BLACK TEXT, NOT RED</div>

同じ結果を得るために使用することができます
