Get <TH> texts into a tab separated string

Question

table_with_headers = $(this.dom.table).find("thead tr th").map(->
  $(this).text()
).get().join("\t")

Can one write it nicer? I especially don't like the inner function in map syntax enforced by CoffeeScript and jQuery.

Answer 1

CoffeeScript is not my forte, however I quite like this approach:

elements =  $(this.dom.table).find("thead tr th")
table_with_headers2 = ($(element).text() for element in elements ).join('\t')

This way you call out which elements you are going to process, and then use a list comprehension. In a style that is closer to JS than true CoffeeScript.

Answer 2

You can use explicit find like so

$ 'thead tr th', @dom.table

and put some indentations instead of braces

table_with_headers = $ "thead tr th", @dom.table
.map -> @.text()
.join '\t'

Also try to use list comprehesion

table_with_headers = [
  $(th).text()
  for th in
  $ "thead tr th", @dom.table
].join '\t'
