如何在运行时提供元素时在JavaScript中获取innerText？ [英] How to get innerText in javascript when elements are supplied in runtime?

问题描述

我试图获取元素的 innerText ，但它返回 undefined 。

code：

 < td id =some-id>< obs conceptId =3156style =textarea/>（此处插入span元素）< / td> 
  

在运行时生成html：

 < td id =some-id>< span class =value> 14< / span>< / td> 
  

我曾尝试使用 document.getElementById（some-id）。 innerText 结果是 undefined 。
我试过使用 document.getElementById（some-id）。innerHTML result是< span class =value> 14 LT; /跨度> 。

Demo小提琴

Javascript

b $ b

  var td = document.getElementById（'some-id'）; 
 alert（td.getElementsByTagName（'span'）[0] .innerHTML）; 
  

你的问题是关于 innerText 只有在IE浏览器中，按照我所知，Firefox和Chrome使用 textContent

带有textContent的小提琴

I'm trying to get the innerText of an element but it's returning undefined.

code:

 <td id="some-id"><obs conceptId="3156" style="textarea"/>(this one here inserts the span element)</td>

generated html during runtime:

 <td id="some-id"><span class="value">14</span></td>

I have tried using document.getElementById("some-id").innerText result was undefined. I have tried using document.getElementById("some-id").innerHTML result was <span class="value">14</span>. I would like to get the value 14.

解决方案

Demo Fiddle
Javascript

var td = document.getElementById('some-id');
alert(td.getElementsByTagName('span')[0].innerHTML);  

And your question about innerText it will work only in IE, as per I know Firefox and Chrome uses textContent

Fiddle with textContent

Hope it helps..!!
