问题描述

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为此提供了一个名为ParagraphFormat()的函数:

CF has a function for this called ParagraphFormat():

<cfset form.userText = paragraphFormat(form.usertext)/>

来自帮助文档 -

替换字符串中的字符:

• 带空格的单个换行符(CR/LF 序列)
• 带有 HTML 段落标签的双换行符 (<p>)

它可能比你想要的更多，因为它还查找双换行符并添加 <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 还有一个增强版本(UDF)，称为paragraph2，可以轻松修改以获得您想要的确切效果.这是链接:

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:
