如何从HTML页面获取标签文本值? [英] How to get label text value form a html page?

问题描述

我有一个html页面，其中html呈现为:

 < div id ='mViB'>< table id ='myTable'>< tbody>< tr>...</tr>< tr> ...</tr>< tr>...</tr>< tr> ....</tr>< tr>< td>< label id ="* spaM4" for ="* zigField4">真是的< span class ='msde32'></span></label></td></tr></tbody></table></div> 

现在，我要执行的操作是获取标签文本"All hell".来自标签.

为此，我同时使用了两个代码: document.getElementById('* spaM4').text 和 document.getElementById('* spaM4').value 他们都没有工作.

我使用了 document.getElementById('* spaM4').innerHTML ，但这也返回了 span类，但是我只想获取文本./p>

不幸的是，元素ID中的星号是第3方代码，我无法更改.

有人可以建议其他方法来获取标签文字吗?

解决方案

尝试一下:

  document.getElementById('* spaM4').textContent 

如果您需要定位<IE9，则需要使用 .innerText

I have a html page , where the html is rendered as :

<div id = 'mViB'>
<table id = 'myTable'>
<tbody>
<tr> ...</tr>
<tr>...</tr>
<tr> ...</tr>
<tr>....</tr>
<tr>
<td>
<label id="*spaM4" for="*zigField4">
All hell.
<span class = 'msde32'></span>
</label>
</td>
</tr>
</tbody>
</table>
</div>

Now what i want to do is get the label text 'All hell.' from the label.

For that purpose i have used both : document.getElementById('*spaM4').text and document.getElementById('*spaM4').value but incidentally none of them worked.

I have used document.getElementById('*spaM4').innerHTML but that returns the span class as well, but i just want to get the text .

Unfortunately, the asterisks in element IDs are 3rd party code and I cannot change it.

Can any one suggest any other way for getting the label text ?

解决方案

Try this:

document.getElementById('*spaM4').textContent

If you need to target < IE9 then you need to use .innerText
