javascript - get text from attribute and format it -

I have a div with data-seat and data-line Property:

  & lt; Div class = 'selected' data-seat = '1' data-line = '1' & gt; & Lt; / Div & gt; & Lt; Div class = 'selected' data-seat = '2' data-line = '1' & gt; & Lt; / Div & gt; & Lt; Div class = 'selected' data-seat = '3' data-line = '1' & gt; & Lt; / Div & gt; & Lt; Div class = 'selected' data-seat = '1' data-line = '2' & gt; & Lt; / Div & gt; & Lt; Div class = 'selected' data-seat = '2' data-line = '2' & gt; & Lt; / Div & gt;    I want a print friendly message for selected seats:  
  var selectedPlaceTextFormated = ''; $ (". Selected"). Each (function () {var selected place = $ (this); Selected placeset text formatted + = "row" + selected location. "(Seat" + location selected. "Data-seat") + ") \ n"; }); Warning (selectedPlaceTextFormated);    This code works well and shows the following:  
  line 1 (seat 1) line 1 (seat 2) line 1 (seat) 3) Line 2 (seat 1) line 2 (seat 2)    But, I want the group seats on seats, that is, I want the following:  
 < Code> line 1 (seats: 1,2,3) line 2 (seats: 1,2)    How can I do this? Thank you   
 
  Here is the code  
  var selectedPlaceTextFormated = ' '; Var row_array = []; $ (". Selected"). {(Selected row_array [Selected place. ("Data-line")] {row_array [selectedPlace.attr ("data-line")] = Selected place (each (function () {var selected location = $ (this); Attr ("data-seat");} and row_re [selected place. ("Data row")] + = ',' + selectedPlace.attr ("data-seat");}); For (line in row_array) {warning ("line" + row + "(seat" + line_ar [row] + ") \ n"); }    and a link to the ferry working here:

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,
