我有一份文本领域投入,使用户能够投入超出段落的内容,即用户可以产生一个新的线。
Problem is when I output that from the database it s all shrunk into one line?
我如何把这一新行变成一个有利于超文本的新行子,以便看用户对案文的投入方式?
感谢
Use the simple_format helper. It s replace all
by <br /> or <p>
参考书:
my_text = "Here is some basic text...
...with a line break."
simple_format(my_text)
# => "<p>Here is some basic text...
<br />...with a line break.</p>"
more_text = "We want to put a paragraph...
...right there."
simple_format(more_text)
# => "<p>We want to put a paragraph...</p>
<p>...right there.</p>"
simple_format("Look ma! A class!", :class => description )
# => "<p class= description >Look ma! A class!</p>"
This css rule should do the trick:
white-space: pre-line;
This also works. Put this in your imput show (change to your class and attribute, tex: @post.content or @post.body).
<%= @class.attribute.html_safe.gsub(/
?/,"<br/>").html_safe %>
