<p>For certain html fragments like <code>&lt;td&gt;test&lt;/td&gt;</code>, div.innerHTML, DOMParser.parseFromString and range.createContextualFragment (without the right context) solutions mentioned in other answers here, won't create the <code>&lt;td&gt;</code> element.</p>
<p>jQuery.parseHTML() handles them properly (I extracted <a href="https://gist.github.com/Munawwar/6e6362dbdf77c7865a99" rel="noreferrer">jQuery 2's parseHTML function into an independent function</a> that can be used in non-jquery codebases).</p>
<p>If you are only supporting Edge 13+, it is simpler to just use the HTML5 template tag:</p>
<pre><code>function parseHTML(html) {
    var t = document.createElement('template');
    t.innerHTML = html;
    return t.content;
}

var documentFragment = parseHTML('&lt;td&gt;Test&lt;/td&gt;');

};|code-block|syntax|javascript|1424177|和here+u可以检查DOM操作React与原生JS的性能|offset|length|1424178|现在你可以简单地使用：|1424179|let+element+=+render(document.body,+`
<div+style="font-size:120%25;line-height:140%25">
++<p+class="bold">New+DOM</p>
</div>
`);|1424180|当然，在不久的将来，您将使用来自内存的引用，因为var+"element“是您在文档中新创建的DOM。|1424181|记住"innerHTML=“非常慢:/|1424182|entityMap|0|LINK|mutability|MUTABLE|url|https://jsperf.com/react-vs-raw-dom-manipulation^0|0|0|1|4|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|10|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|11|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|12|8|@]|9|@$I|13|J|14|1|15]]|A|$]]|$1|K|3|L|5|6|7|16|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|17|8|@]|9|@]|A|$E|F]]|$1|O|3|P|5|6|7|18|8|@]|9|@]|A|$]]|$1|Q|3|R|5|6|7|19|8|@]|9|@]|A|$]]|$1|S|3|-4|5|6|7|1A|8|@]|9|@]|A|$]]]|T|$U|$5|V|W|X|A|$Y|Z]]]]

<p>Fastest solution to render DOM from string:</p>

<pre><code>let render = (relEl, tpl, parse = true) =&gt; {
  if (!relEl) return;
  const range = document.createRange();
  range.selectNode(relEl);
  const child = range.createContextualFragment(tpl);
  return parse ? relEl.appendChild(child) : {relEl, el};
};
</code></pre>

<p>And <a href="https://jsperf.com/react-vs-raw-dom-manipulation" rel="nofollow noreferrer">here</a> u can check performance for DOM manipulation React vs native JS</p>

<p>Now u can simply use:</p>

<pre><code>let element = render(document.body, `
&lt;div style="font-size:120%;line-height:140%"&gt;
  &lt;p class="bold"&gt;New DOM&lt;/p&gt;
&lt;/div&gt;
`);
</code></pre>

<p>And of course in near future u use references from memory cause var "element" is your new created DOM in your document.</p>

<p>And remember "innerHTML=" is very slow :/</p>

<p>I have an HTML string representing an element: <code>'&lt;li&gt;text&lt;/li&gt;'</code>. I'd like to append it to an element in the DOM (a <code>ul</code> in my case). How can I do this with Prototype or with DOM methods?</p>

<p>(I know i could do this easily in jQuery, but unfortunately we're not using jQuery.)</p>

我有一个表示元素的超文本标记语言字符串：'<li>text</li>'。我想把它附加到DOM中的一个元素(在我的例子中是一个ul )。我如何使用Prototype或DOM方法来实现这一点？(我知道在jQuery中可以很容易做到这一点，但不幸的是，我们没有使用jQuery。)
