Line break for ruby ​​string placeholder

Question

<%= f.text_area :comment, placeholder: "Comment on your track or" + \n + "share your favorite lyrics" %> 

How can I make placebolder break a line like

The solution was only to add a space so that the next line wraps around:

 placeholder: "Comment on your track or share your favorite lyrics" %> 

Pretty ugly but least complicated

Answer 1

A newline character \n must be included between doubles, however HTML does not allow the use of a line feed, but Thomas Hunter suggested hacking , which consists in using a bunch of white spaces, for example:

 <%= f.text_area :comment, placeholder: "Comment on your track or share your favorite lyrics" %> 

You can also use the title attribute.

Answer 2

In Ruby, generally speaking, "\n" is the newline character.

eg:.

  puts "first line\nsecond line" => first line second line 

However, in your case:

it seems you are trying to use a newline in the .erb expression <%= ... %>

This does not work, because it will only format a new line in a raw HTML sum , but in formatted HTML you will not see a new line! :-)

To see a new line in formatted HTML , you need to do something like this:

• either put two lines in separate div or span
• or put in the string <br /> instead of "\n" - <br \> HTML newline character

Answer 3

You are creating HTML code. HTML doesn't care about whitespace in the actual code. You need a break in the HTML itself. However, it seems like this other question. Can you have multi-line HTML5 placeholder text in <textarea>? that HTML does not allow line breaks in the placeholder field.
