在DIV中访问textarea的最佳方式 [英] Best way to access a textarea within a DIV

问题描述

你好


我有一个包含各种元素的DIV，例如：


< div ARID =" 8" ARType = QUOT;字符" ARDBN =简短描述>

< label class =" label f9" for =" arid8" Short Description< / label>

< textarea class =" text sr"包裹= QUOT;脱" ID = QUOT; arid8" rows = 1>< / textarea>

< / div>


我有一个变量div，包含DIV'和div [x]包含

我需要的实际DIV。


访问内部文本区域的最佳（或最强大）方式是什么？

因为我想在textarea字段中添加一些文本。我知道怎么用

添加文字，但想知道访问textarea的最佳方式。

假设id是唯一的：

var txt = document.getElementById（" arid8"）。value;


BTW为什么你使用< textarea /而不是< input type =" text" /？

为什么输入字段优于textarea？

如果你试试html样本，var txt =

document.getElementById（" arid8"）。value;不行。在IE或FF中没有工作

。


它应该可以工作，但似乎没有。所以我的下一个想法是怎么可以

我得到的DIV的子元素我知道包含textarea？


textarea是这样用户可以输入多个文本行。

Hello

I have a DIV with various elements eg:

<div ARID="8" ARType="Char" ARDBN="Short Description">
<label class="label f9" for="arid8"Short Description</label>
<textarea class="text sr " wrap="off" id="arid8" rows=1></textarea>
</div>

I have a variable, divs, which contains the DIV''s and divs[x] contains
the actual DIV I need.

What is the best (or most robust) way to access the inner textarea -
because I want to add some text to the textarea field. I know how to
add the text but want to know best way to access the textarea.

Assumng that the id is unique:
var txt = document.getElementById("arid8").value;

BTW why are you using a <textarea /and not <input type="text" /?

Why would an input field be preferable to a textarea?

if you try the html sample, var txt =
document.getElementById("arid8").value; doesn''t work. Didn''t work
either in IE or FF.

It should work but it doesn''t seem to. So my next thought is how can
I get the child elements of the DIV that I know contains the textarea?

the textarea is so users can enter multiple lines of text.
