通过 oninput 函数获取可编辑 <td> 标签的值？

Question

<td contenteditable="true" class="name_of_child" oninput="set_text(this,'name_of_child_1')"></td><td contenteditable="true" class="date_of_birth" oninput="set_text(this,'date_of_birth_1')"></td><td contenteditable="true" class="living_or_deceased" oninput="set_text(this,'living_or_deceased_1')"></td>我想通过这样oninput的表td元素中的函数获取文本，但遗憾的是，这适用于输入字段，但不适用于表td标签。有没有办法使用或任何其他方式获取td文本？oninput

Answer 1

为什么不更抽象一些呢？

const data = {}

const setup = () => {

    document.querySelectorAll('td').forEach(td => td.addEventListener('input', setText));

  

  const btn = document.querySelector('button');

  btn.addEventListener('click', (event) => console.log(data));

}

const updateObject = (key, value) => data[key] = value;

const setText = (event) => {

    const target = event.currentTarget;

  const key = target.dataset.var;

  const value = target.textContent;

  

  updateObject(key, value);

}

window.addEventListener('load', setup)

td {

  background: red;

  min-width: 5em;

}

<table>

  <tr>

    <td contenteditable="true" data-var="name_of_child"></td>

    <td contenteditable="true" data-var="date_of_birth"></td>

    <td contenteditable="true" data-var="living_or_deceased"></td>

  </tr>

</table>

<button>

Show Object

</button>

Answer 2

您可以为每个对象提供唯一的 id td，然后尝试通过将 id 传递给oninput函数来访问该值。

<td id="td1" contenteditable="true" class="name_of_child"oninput="set_text(this,'td1')"></td>

<td id="td2" contenteditable="true" class="date_of_birth" oninput="set_text(this,'td2')"></td>

<td id="td3" contenteditable="true" class="living_or_deceased" oninput="set_text(this,'td3')"></td>

set_text功能：

function set_text(this, id) {

    var val = document.getElementById(id).textContent

}

Answer 3

读取您传入的引用的 innerHTML 或 textContent 以获取用户键入的内容。

function set_text(td, foo) {

   console.log(td.innerHTML);

}

table, tr { width: 100%;}

td { width: 33%;}

<table>

  <tr>

    <td contenteditable="true" class="name_of_child" oninput="set_text(this,'name_of_child_1')">x</td>

    <td contenteditable="true" class="date_of_birth" oninput="set_text(this,'date_of_birth_1')">y</td>

    <td contenteditable="true" class="living_or_deceased" oninput="set_text(this,'living_or_deceased_1')">z</td>

  </tr>
