Add a linefeed ("\n") to the output:

<pre><code>&lt;textarea&gt;Hello


Bybye&lt;/textarea&gt;
</code></pre>

Will have a newline in it.

blocks|key|1549374|text|您可以使用\r\n或System.Environment.NewLine。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1549375|entityMap^0|5|4|A|Q|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

You could use <code>\r\n</code>, or <code>System.Environment.NewLine</code>.

blocks|key|1549439|text|我相信这将会奏效：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1549440|TextArea.Text+=+"Line+1"+&+vbCrLf+&+"Line+2"|code-block|syntax|javascript|1549441|如果你想少一点VB6的话，可以用System.Environment.NewLine来代替vbCrLf。|1549442|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

I believe this will work:

<pre><code>TextArea.Text = "Line 1" &amp; vbCrLf &amp; "Line 2"
</code></pre>

System.Environment.NewLine could be used in place of vbCrLf if you wanted to be a little less VB6 about it.

blocks|key|1764475|text|在文本区域中，就像在表单输入中一样，只需一个普通的换行符就可以了：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1764476|<textarea>
This+is+a+text+area
line+breaks+are+automatic
</textarea>|code-block|syntax|javascript|1764477|如果你谈论的是页面上的普通文本，(或者如果只是使用普通的'ole+HTML4)就是换行符。|1764478|然而，我要说的是，您通常并不真正想要换行符。通常，您的文本被分成多个段落：|1764479|
++This+is+some+text


++This+is+some+more
|1764480|这要好得多，因为它给出了一个线索，说明你的文本是如何被机器阅读的。阅读它的机器包括针对部分视力或盲人的屏幕阅读器，将文本分成段落使其有机会正确地呈现给这些用户。|1764481|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|T|8|@]|9|@]|A|$]]|$1|K|3|L|5|D|7|U|8|@]|9|@]|A|$E|F]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

In a text area, as in the form input, then just a normal line break will work:

<pre><code>&lt;textarea&gt;
This is a text area
line breaks are automatic
&lt;/textarea&gt;
</code></pre>

If you're talking about normal text on the page, the &lt;br /&gt; (or just &lt;br&gt; if using plain 'ole HTML4) is a line break.

However, I'd say that you often don't actually want a line break. Usually, your text is seperated into paragraphs:

<pre><code>&lt;p&gt;
 This is some text
&lt;/p&gt;
&lt;p&gt;
 This is some more
&lt;/p&gt;
</code></pre>

Which is much better because it gives a clue as to how your text is structured to machines that read it. Machines that read it include screen readers for the partially sighted or blind, seperating text into paragraphs gives it a chance of being presented correctly to these users.

blocks|key|1764566|text|如果你从数据库或者类似的地方插入文本(通常是这样的)，把所有的“<br+/>”转换成&vbCrLf。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1764567|entityMap^0|W|6|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

If you're inserting text from a database or such (which one usually do), convert all "<code>&lt;br /&gt;</code>"'s to &amp;vbCrLf. Works great for me :)

blocks|key|1764621|text|如果不是vb，你可以使用&#013;&#010;+(+cr，lf的ascii代码)|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1764622|entityMap^0|C|C|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

If it's not vb you can use <code>&amp;#013;&amp;#010;</code> (ascii codes for cr,lf)

blocks|key|1764669|text|像"\n“这样的转义序列可以很好地工作！即使有文本区！我将一个带有"\n“的java字符串传递给一个html文本区域，它工作得很好，因为它可以在java的控制台上工作！|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1764670|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Escape sequences like "\n" work fine ! even with text area! I passed a java string with the "\n" to a html textarea and it worked fine as it works on consoles for java!

blocks|key|1764749|text|下面是我用纯PHP和CSS编写的方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1764750|/**+PHP+code++++*/
<?php
++++$string+=+"the+string+with+linebreaks";
++++$string+=+strtr($string,array("."=>".\r\r",":"=>"+:+\r","-"=>"\r+-+"));
?>|code-block|syntax|javascript|1764751|和CSS：|1764752|.your_textarea_class+{
style='white-space:pre-wrap';
}|1764753|你可以用regex做同样的事情(我正在学习如何使用关联数组用pregreplace构建regex，似乎更适合添加\n\r来显示断点)。|1764754|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Here is my method made with pure PHP and CSS :

<pre><code>/** PHP code */
&lt;?php
 $string = "the string with linebreaks";
 $string = strtr($string,array("."=&gt;".\r\r",":"=&gt;" : \r","-"=&gt;"\r - "));
?&gt;
</code></pre>

And the CSS :

<pre><code>.your_textarea_class {
style='white-space:pre-wrap';
}
</code></pre>

You can do the same with regex (I'm learning how to build regex with pregreplace using an associative array, seems to be better for adding the \n\r which makes the breaks display).
