Question

In my form, I have a textarea field where user can enter data and press ‘Enter’ to put line breaks and continue entering data.

When I am retrieving data from the database, I need to remove all line breaks and store that data in a a JavaScript array.

In the example below, I am retrieving a note (which contains several line breaks <br/>) and storing in in an array called ‘exp_from_db’

exp_from_db[1]= '<%= note.NOTE_VALUE %>';

My question is how do I remove those line breaks in <%= note.NOTE_VALUE %> before storing it in the javascript array.

Thanks for your help.

Answer 1

If the string <br/> and variations of it (<br>, <br />, <br >) are all you want to remove, gsub is one way

note.NOTE_VALUE.gsub(/<br\s*\/?>/, '')

If you always want to strip this, you can modify the getter for NOTE_VALUE in the ActiveRecord class

def NOTE_VALUE
  read_attribute("NOTE_VALUE").gsub(/<br(\s*\/)?>/, '')
end
