javascript - Railscast #383 add/remove uploader form and script via AJAX -

-

i've got uploader working railscast #383, there way add , remove uploader link via ajax?

i need pass in "service" instance id.

the code add or remove via ajax below:

<%= s3_uploader_form post: images_url(:service_id => service.id), as: "image[url]" %>   <%= file_field_tag :file, multiple: true %>  <% end %>   <script id="template-upload" type="text/x-tmpl">    <div class="upload">      {%=o.name%}      <div class="progress"><div class="bar" style="width: 0%"></div></div>    </div>   </script>

ok figured out. main problem having uploader coffeescript not executing again after form added via ajax. revised #136 railscast got basic ajax form working, in order uploader form working via ajax, included uploader coffeescript normal javascript in new.js.erb file. way when new.js.erb file executed, loads form , executes uploader javascript.

new.js.erb:

$('#new_link').hide().after('<%= j render("images/form") %>');  jquery(function() {   return $('#fileupload').fileupload({     add: function(e, data) {       var file, types;       types = /(\.|\/)(gif|jpe?g|png)$/i;       file = data.files[0];       if (types.test(file.type) || types.test(file.name)) {         data.context = $(tmpl("template-upload", file));         $('#fileupload').append(data.context);         data.form.find('#content-type').val(file.type);         return data.submit();       } else {         return alert("" + file.name + " not gif, jpeg, or png image file");       }     },     progress: function(e, data) {       var progress;       if (data.context) {         progress = parseint(data.loaded / data.total * 100, 10);         return data.context.find('.bar').css('width', progress + '%');       }     },     done: function(e, data) {       var content, domain, file, path, to;       file = data.files[0];       domain = $('#fileupload').attr('action');       path = $('#fileupload input[name=key]').val().replace('${filename}', file.name);       = $('#fileupload').data('post');       content = {};       content[$('#fileupload').data('as')] = domain + path;       $.post(to, content);       if (data.context) {         return data.context.remove();       }     },     fail: function(e, data) {       alert("" + data.files[0].name + " failed upload.");       console.log("upload failed:");       return console.log(data);     }   }); });
