问题描述
例如：

A user submits a form with a <textarea name="mytext" cols="35" rows="2"></textarea> and presses ENTER within it. How would I replace the CR-LF with a <br />?
推荐答案
CF有一个称为ParagraphFormat（）的函数：
CF has a function for this called ParagraphFormat():
<cfset form.userText = paragraphFormat(form.usertext)/>
从帮助文档 -
字符中的字符：
- 包含空格的单个换行符（CR / LF序列）
- 带有HTML段落标签的换行符（
< p>）
- Single newline characters (CR/LF sequences) with spaces
- Double newline characters with HTML paragraph tags (
<p>)
比您想要的更多，因为它也会查找双重换行符并添加< p> 和< / p> 标签。
It may do more than you want in that it also looks for double line breaks and adds <p> and </p> tags.
Ben还有一个名为paragraph2的增强版本（UDF），很容易修改，想。以下是链接：
Ben also has an enhanced version (a UDF) called paragraph2 that would be easy to modify to get the exact affect you want. Here's the link:
