Hi all! I want to add alert message via jquery when User clicks star.
But, It can’t work.
Please teach me some advice.

Thanks!

posts/index.html.erb

...
<% @posts.each do |post| %>
  <tr>
    <td><%= post.id %></td>
    <td><%= post.content %></td>
    <td></td>
    <div id="like">
      <td>like</td>
    </div>
    <td><div id="star">star</div></td>
    <td><%= post.created_at.strftime("%Y年%m月%d日%H:%M:%S") %></td>
<% end %>
</tr>
</table>

....

application.js

$(document).ready(function() {
   $("#star").click(function(){
     alert("add_star");
   })
 });

Hi,

Show us the error you are getting on that.

Also, check your html code generated to see if the javascript
libraries are loading correctly, in this case, the jquery library.

If you are not on rails 3.1 you are probably loading the prototype
files instead the jquery as needed.

You have multiple divs with ID = star. Change this to class and update
the
script and it should work.
