Rails将&#39;\\ n&#39;替换为&#39; <br/> &#39; 问题

Question

The input is a textarea type

so i got the data from the controller like this,

'firstline \n secondline \n thirdline"

i want to change this to

'firstline <br/> secondline <br/> thirdline"

I googled, and found this.

description = appointment[:description].to_s.gsub(/\n/, "<br/>")

but the weird thing is if i print this, it shows a weird text like this,

code,

<%=Rails.logger.debug("***description***" + description)%>

result,

<br/>3rd linen***1st line

the more weird thing is, i have to put this params to call a javascript function like this,

<span class="hotspot" onmouseover="tooltip.show(<%=user_list%>,&quot;<%=description%>&quot;);" onmouseout="tooltip.hide();">
     <%=h appointment[:users] %>
</span>

focus on the <%=description%>

in here i got an error, and shows like this,

<span class="hotspot" onmouseover="tooltip.show([],&quot;1st line
&lt;br/&gt;2nd line
&lt;br/&gt;3rd line&quot;);" onmouseout="tooltip.hide();">

Uncaught SyntaxError: Unexpected token ILLEGAL

any good idea?

Answer 1

尝试这个

"firstline \n secondline \n thirdline".to_s.gsub(/\n/, "<br/>").html_safe

Answer 2

May be this will work

desc = appointment[:description].to_s
description = desc.split("\n").join("<br/>")

Answer 3

尝试这个。

description = appointment[:description].to_s.gsub(/\n/, "<br/>").html_safe
