最新JS示例：

<template id="woof-sd-feature-box">
<div class="woof-sd-feature-box" data-key="__KEY__" data-title="__TITLE__" data-data="__OPTIONS__">
    <h4>__TITLE__</h4>
    <div class="woof-sd-form-item-anchor">
        <img src="img/move.png" alt="">
    </div>
</div>

</template>

<script>
create(example_object) {
        let html = document.getElementById('woof-sd-feature-box').innerHTML;
        html = html.replaceAll('__KEY__', example_object.dataset.key);
        html = html.replaceAll('__TITLE__', example_object.dataset.title);
        html = html.replaceAll('__OPTIONS__', example_object.dataset.data);
        //convertion HTML to DOM element and prepending it into another element
        const dom = (new DOMParser()).parseFromString(html, "text/html");
        this.container.prepend(dom.querySelector('.woof-sd-feature-box'));
    }
</script>

这里有一个简单的方法：

String.prototype.toDOM=function(){
  var d=document
     ,i
     ,a=d.createElement("div")
     ,b=d.createDocumentFragment();
  a.innerHTML=this;
  while(i=a.firstChild)b.appendChild(i);
  return b;
};

var foo="<img src='//placekitten.com/100/100'>foo<i>bar</i>".toDOM();
document.body.appendChild(foo);

您可以使用以下函数将文本“HTML”转换为元素

函数htmlToElement（html）{var element=document.createElement（'div'）；element.innerHTML=html；返回（元素）；}var html=“<li>text和html</li>”；var e=htmlToElement（html）；

这是我的代码，它有效：

function parseTableHtml(s) { // s is string
    var div = document.createElement('table');
    div.innerHTML = s;

    var tr = div.getElementsByTagName('tr');
    // ...
}

无需任何调整，您获得了一个本地API：

const toNodes = html =>
    new DOMParser().parseFromString(html, 'text/html').body.childNodes[0]

const stringToHtml = function (str) {
    var parser = new DOMParser();
    var doc = parser.parseFromString(str, 'text/html');
    return doc.body;
}
