Re: Merging array with same key - HELP

hi,
 I''m getting value like
{"1stjan1"=>"01/01/2009",
"10thjan1"=>"10/01/2009",
"1stjan2"=>"01/01/2009",and so}
for the code

array3 = {}
array1.each_with_index do |x, i|
  array3[x] = array2[i]
end

I need to merge the value but the key(date) should be same.

Thanks.

Re: Merging array with same key - HELP

Re: Merging array with same key - HELP

Hi,

hash = {}
array1.uniq.each { |d| hash[d] = [] }
array1.each_with_index { |x,i| hash[x] << array2[i] }
hash.each_key { |key| hash[key] = hash[key].join(''-'') }
hash.inspect # =>
{"01/01/2009"=>"1stjan1-1stjan2-1stjan3",
"10/01/2009"=>"10thjan1-10thjan2"}

Enjoy,

Re: Merging array with same key - HELP

Hi,

I got a table like this

---------------------------------------------------------------
id | what   | when      | color  |   to      | description     |
---------------------------------------------------------------
1  | test   |01/01/2009 | red    |04/01/2009 | hi this is test |
---------------------------------------------------------------
2  | test2  |02/01/2009 | green  |04/01/2009 | hi this is test |
---------------------------------------------------------------
3  | test3  |01/01/2009 | blue   |04/01/2009 | hi this is test |
---------------------------------------------------------------
4  | test4  |02/01/2009 | orange |04/01/2009 | hi this is test |
---------------------------------------------------------------

I had fetch the value from the database in such a way like this

##############################
#[JavaScript source with ROR]#
##############################

var dAb = new Array();
var x = 0;
var event_task_today ='''';
var event_task ='''';

<% @eventall.each do |d| %>
 var DBdate1 = ''<%= d.when%>'';
 var eventdate1 = DBdate1.split(''/'');
 var task_date1 =eventdate1[2]+eventdate1[1]+eventdate1[0];
 dAb[x++] =  task_date1+" <div align=''lef'' 
style=''background:<%=d.color%>;color:white;''><%=
d.what%></div>";
<% end %>

If I alert ''dAb''value I''m getting like this
     *****

20090101 <div align=''left'' 
style=''background:red;color:white;''>test</div>,20090102
<div
align=''left''
style=''background:green;color:white;''>test2</div>,20090101
<div align=''left'' 
style=''background:blue;color:white;''>test3</div>,20090102
<div
align=''left''
style=''background:orange;color:white;''>test4</div>

I need to have JavaScript variable ''dAb''like this
                          ********

20090101 <div align=''left'' 
style=''background:red;color:white;''>test</div><BR><div
align=''left''
style=''background:blue;color:white;''>test3</div>,20090102
<div
align=''left''
style=''background:green;color:white;''>test2</div><BR><div
align=''left''
style=''background:orange;color:white;''>test4</div>

<BR> tag should be placed in between the values with same date ,date 
should be printed only once.

PLEASE ADVICE.

Thanks in advance.
