剥离所有表元素的HTML属性

我有一个HTML表

我想要的是完全摆脱所有HTML属性，因此我的表看起来像这样：

<table>
    <thead>
        <tr>
            <th>...</th>
            ...
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>...</td>
            ...
        </tr>
    </tbody>
</table>

我该如何使用普通JavaScript？

我在这里找到了几个类似的主题，但是它们要么使用jQuery（不允许使用我的 ），要么对我不起作用。

<table class="wikitable sortable jquery-tablesorter" style="margin-left:auto;margin-right:auto;text-align: right">
  <thead>
    <tr>
      <th data-sort-type="number" class="headerSort" tabindex="0" role="columnheader button" title="Sort ascending">Rank
      </th>
      <th class="headerSort" tabindex="0" role="columnheader button" title="Sort ascending">Country/Territory
      </th>
      <th class="headerSort" tabindex="0" role="columnheader button" title="Sort ascending">Int$
      </th>
    </tr>
  </thead>

您可以遍历所有节点并使用.getAttributeNames()获取其属性名称，可以使用.removeAttribute()将其删除：

[...document.querySelectorAll('*')].forEach(node => node.getAttributeNames().forEach(attr => node.removeAttribute(attr)))

答案 1 :(得分：1)

像这样-我假设您想保留图片src和href

我已将表格缩短至SO限制之内

document.querySelectorAll("#tableContainer *").forEach(function(tag) {
  [...tag.attributes].forEach(function(attr) {
    if (["href","src"].indexOf(attr.name) ==-1) tag.removeAttribute(attr.name)
  })
})
// console.log(document.querySelector("#tableContainer").innerHTML)
<div id="tableContainer">
  <table class="wikitable sortable jquery-tablesorter" style="margin-left:auto;margin-right:auto;text-align: right">
