使用Rails中的Ajax更新Div而不重新加载页面

Question

In my View af_form.html.erb

I have a button for trrigering ajax call

  <%= button_to('update ', {:action => 'update', :thingyid => 314}, :method => :get, :remote => true , :'data-update-target' => 'af_stat' ) %>

    <div id="af_stat" >
    <h3>Tiltle : 
      <%= @kk %>
    </h3>   

somebody says I should have a file called _af_form.html.erb what should the _af_form.html.erb should be?

In my controller welcome , there is an method

  def update

    @kk = @kk +1

    render :partial => 'af_form', :content_type => 'text/html'
  end   

I heard someone said..."just same as af_form.js.erb" ? isn't it stupid? copy two identical files.and disobey DRY rule.

and it doesn't work . what's wrong. anyone can help me. thanks you very much.

i just want to change the view af_form.html.erb not _af_form.html.erb , why should i need _af_form.html.erb

Answer 1

在update.js.erb尝试这个

$('#af_stat h3').text('Title: <%= escape_javascript @kk %>');
