Textarea contenteditable
提问by Antony Carthy
I am trying to make a textarea content editable and I am failing. I am using this code:
我正在尝试使 textarea 内容可编辑，但失败了。我正在使用此代码：
<textarea id='' class='' name='notes' rows='12' cols='67' contenteditable='true' ></textarea>
I am expecting a result like http://html5demos.com/contenteditable
我期待像http://html5demos.com/contenteditable这样的结果
Does anyone have an idea why it's not working?
有谁知道为什么它不起作用？
Edit:
编辑：
I am doing this because I am trying to do a oneliner to add a control to a form in which (HTML) formatted content can be pasted and retain its formatting. I am trying to do this without fuss and without javascript code. It appears this is not possible. I will close this question in a day if no further input to the contrary is added.
我这样做是因为我正在尝试做一个oneliner来将一个控件添加到一个可以粘贴（HTML）格式内容并保留其格式的表单中。我正在努力做到这一点，没有大惊小怪，没有 javascript 代码。看来这是不可能的。如果没有进一步的相反输入，我将在一天内关闭这个问题。

Have you set the right doctype at the top of your page? For HTML5 you need the following doctype:
您是否在页面顶部设置了正确的文档类型？对于 HTML5，您需要以下文档类型：
<!DOCTYPE html>
Also, why a textarea? textareas are already editable.
另外，为什么是文本区域？textareas 已经是可编辑的。

They are not using a textarea, textareas are already editable. This is what they are using
他们没有使用 textarea，textareas 已经是可编辑的。这是他们正在使用的
<section contenteditable="true" id="editable">
<h2>Go ahead, edit away!</h2>
<p>Here's a typical paragraph element</p>
<ol>
<li>and now a list</li>
<li>with only</li>
<li>three items</li>
</ol>
</section>

I don't mean to repeat anything, but I've put together a demo that shows what is happening.
我不想重复任何事情，但我已经制作了一个演示来展示正在发生的事情。
Just run that, edit what you wish and click the 'Output Formatted Content' statement to receive an alert message with an output of the actual html-formatted content in the contenteditable element. As for adding formatting, etc, you'll need to make buttons that call a text-modifying function on whatever is highlighted. Yeah, that part will be fun.
只需运行它，编辑您想要的内容，然后单击“输出格式化内容”语句以接收警告消息，其中包含 contenteditable 元素中实际 html 格式内容的输出。至于添加格式等，您需要制作按钮，在突出显示的任何内容上调用文本修改功能。是的，那部分会很有趣。
Nonetheless, I hope this helps.
尽管如此，我希望这会有所帮助。

Given your comment responses, I would recommend any of the excellent WYSIWYG editors out there. No need to re-invent the wheel, and I don't think contenteditablewouldn't have met your needs anyway.
鉴于您的评论回复，我会推荐任何优秀的 WYSIWYG 编辑器。无需重新发明轮子，我认为contenteditable无论如何都不会满足您的需求。
My personal favorite is CKEditor, but there are many, many others. TinyMCEis also very popular.
