如何处理HTML表单中的换行符？

Question

I have a form with a textarea and need to submit multiple lines of input to the textarea .

I use :

rows = [('a','b'), ('c','d')]
data_set = [ '%s\n' % '|'.join(row) for row in rows ]  # Note : ADDED '\n'
data_dump = ''.join(data_set)

from mechanize import Browser
br = Browser()
br.open('http://example.com/page.html')
br.select_form(nr=1)
br.form['my_text_area']=data_dump
br.submit()

Problem:

• Webserver is not able to see the input as multiple lines.
• ADDED \\n is not working for simulating line breaks in the inputs.

What am I doing wrong ?

Feel free to ask for more info if I have missed something !

Update

I also tried \\n\\r in place of \\n , but the problem persists.

Answer 1

I figured it out with the help of https://stackoverflow.com/users/87015/salman-a

CR = \\r LF = \\n

And HTML forms take a line-break as CRLF , so therefore :

\\r\\n worked !
