javascript - Attach data to HTML nodes -


this question has been asked before, of answers revolve around html5.

my doctype is:

<!doctype html public "-//w3c//dtd html 4.01 transitional//en" "http://www.w3.org/tr/html4/loose.dtd">

i need attach data (phone dialling code) option values of select:

<select id="id_creditcardcountry">   <option value="ax">aland islands - ax</option>  <option value="al">albania - al</option>  <option value="dz">algeria - dz</option><!--e.g. attach dial code "(+213)" --> <option value="as">american samoa - as</option> <option value="ad">andorra - ad</option> <option value="ai">anguilla - ai</option> etc

there seem numerous ways accomplish this. need find best 1 (by best mean cross browser , efficient).

  • the jquery "data" function http://docs.jquery.com/core/data -- if best method, can give guidance of how use in instance?
  • set data based on element id - involves having give id every option in select.
  • further suggestions?

you use:

$("#id_creditcardcountry option[value='ax']").data("dial-code", "+213");

if have js array of countries , dial codes loop through them all:

for(var = 1; <= countryarray.length; i++){     $("#id_creditcardcountry option[value='"+countryarray[i]+"']").data("dial-code", ""+dialcodearray[i]+""); }

however, may consider doing server side if you're outputting list of countries. example:

<option value="ax" data-dial="+213">aland islands - ax</option>

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
