I'm using a javascript function to insert html code into my page (following the Railscast on nested models)
The function that inserts the javascript is this:
function add_result(link, association, content) {
var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g"); var linkrow = $(link).up("tr");
linkrow.insert({ after: content.replace(regexp, new_id) }); }
And this is the html.erb that is inserted:
<% for c in @picture_fields %>
<% if c == "intervention" %> <tr class="pictureclass"> <td class="name"><%=t 'form.results.picture.'+c%></td> <td><%= f.radio_button c, t('form.results.picture.interventionoptions.option1')%><%=t 'form.results.picture.interventionoptions.option1'%><%= f.radio_button c, t('form.results.picture.interventionoptions.option2')%><%=t 'form.results.picture.interventionoptions.option2'%><%= f.radio_button c, t('form.results.picture.interventionoptions.option3')%><%=t 'form.results.picture.interventionoptions.option3'%></td> <td></td> </tr>
<% elsif c == "couchetype" %> <tr class="pictureclass"> <td class="name"><%=t 'form.results.picture.'+c%></td> <td><%= f.text_field :selected_couchetypes, :readonly=>true %></
<td class="more"><%= link_to( image_tag('more.png', :border=>0, :id=>"new_results_pictures_results_pictures_couchetype"), {:controller=>"thesaurus", :action=>"list", :id=>"new_results_pictures_results_pictures_couchetype"}, { :popup=>['thesaurus', 'height=800,width=750,location=no,scrollbars=yes']}) %> </td> </tr>
<%else %> <tr class="pictureclass"><td></td><td ></td></tr> <tr class="pictureclass"> <td class="name"><%=t 'form.results.picture.'+c%></td> <td><%= f.text_field c, :class=>"number"%></td> </tr>
<% end %>
<% end %> <tr class="pictureclass"><td></td><td><span class="right"><%= f.hidden_field :_destroy %><%= link_to_function t('form.results.picture.destroy'), "remove_fields(this, '.pictureclass')"%></span></td></tr>
When the html is inserted, there is a size="30" attribute for the text input field:
<input type="text" size="30" name="sample[treatments_attributes][0] [results_pictures_attributes][1273597816957][couchenum]" id="sample_treatments_attributes_0_results_pictures_attributes_1273597816957_couchenum" class="number">
But I have no idea how it got there. Any ideas?
