如何使带有 Rails 链接的 Div 可点击？

Question

I have a large div:

.limeskin:hover {
  background: #eee;
  cursor: pointer;
  display: block;
}

that I want to be clickable. Because I'm using Rails I need to have a Rails link be clickable: For example

<%= link_to 'Edit Your Email Address', edit_user_path %>

I'm struggling to this.

Here is the whole block:

<% @user.posts.each do |post| %>
     <div class="lists">
      <ol class="limeposts">
       <li>
        <div class="limeskin">
          <div class="limebox">
            <div class="limecost">
              <b>Price:</b>
              <%= number_to_currency(post.price, :unit => "R") %><br>
              [...]
<% end %>

Any simple legal workable answers?

Thanks

Answer 1

link_to can accept a block:

<%= link_to root_path do %>
  <div>Hey!</div>
<% end %>

This will surround the div with <a> tags.

Or if you have a big div and want to make it "clickable", using jQuery:

# html.erb
<div class="limeskin">
  <div class="limebox">
    <div class="limecost">
      <b>Price:</b>
      <%= number_to_currency(post.price, :unit => "R") %><br>
      #[...]
    </div>
  </div>
</div>

# jQuery.js
$('.limeskin').click( function(event) {
  var clicked_div = $(this);
  # do stuff with the event object and 'this' which 
  # represent the element you just clicked on
});

使用 javascript（我推荐 jQuery）使动作真正发生，使用 CSS hover选择器修改 div 背景和光标（将光标从箭头更改为手形）。

Using Link_to as below would be sufficient even when you have a big block including multiple tags:

<%= link_to desired_path do %>
    <div class="linkable">
        <another div>
             ... some other tags
        </another div>
    </div>
<% end %>

and I recommend you to use a different background color for mouse over events because it shows the viewer that it's a link!

In you .css file:

.linkable:hover{
    background-color: red;

}
