javascript - Upload button will not fire programmatically -


i have button want use "upclick"-plugin uploading files

<script type="text/javascript" src="~/scripts/upclick-min.js"></script>  <input type="button" id="uploader" value="upload" >  <script type="text/javascript">     var uploader = document.getelementbyid('uploader');     upclick(      {       element: uploader,       action: '/path_to/you_server_script.php',        onstart:         function(filename)         {           alert('start upload: '+filename);         },       oncomplete:         function(response_data)          {           alert(response_data);         }      });

now button works in , opens "open file"-dialogue, cannot seem fire "click"-event on programmatically. ive tried different ways of writing syntax-wise:

if (ui.draggable.hasclass('ui-dragdrop-picelement')) {                         //$("uploader").trigger("click");                         //$("uploader").click();                         //$('uploader').click();                         //$('#uploader').click();                         //$("#uploader").click();                          //$("#uploader").trigger("click");                           //$('button#uploader').trigger('click');                         $('#uploader').trigger('click');                          alert("w00t");                      }

and on - idea why wont fire - alert message!

$("uploader")...

this isn't valid. there no <uploader> element.

your last .click uses correct selector, you'll want use .trigger() event:

$("#uploader").trigger("click");

you'll benefit lot going through official jquery tutorial: http://try.jquery.com.

Why does Ruby on Rails generate add a blank line to the end of a file? -

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 ...
