所以我想在onclick上只显示一个元素。
我发现这段代码很有用,但是我想稍微调整一下。让我告诉你我的意思:
function() {
var options = $('.some_class').hide();
$('.add').click(function() {
if(options.length) {
options.first().show();
options = options.slice(1);
}
});
})
这是我想逐个展示的元素:
<% @pets.each do |pet| %>
<table class="table">
<thead>
<tr>
<th>Name</th>
<th>Type</th>
<th>Sex</th>
<th>Age</th>
<th>breed</th>
<th>Size</th>
<th>Picture</th>
<th>Description</th>
<th>Shelter_id</th>
<th>Shelter</th>
<th>Phone</th>
<th>Email</th>
<th>City</th>
<th>Zip</th>
<th>Like</th>
</tr>
</thead>
<tbody>
<tr>
<td><%= pet.name %></td>
<td><%= pet.species %></td>
<td><%= pet.sex %></td>
<td><%= pet.age %></td>
<td><% pet.breeds.each do |breed| %>
<li><%= breed.name %></li>
<%end%>
</td>
<td><%= pet.size %></td>
<td><%= image_tag pet.picture %></td>
<td><%= pet.description %></td>
<td><%= pet.shelter_id %></td>
<% shelter = Shelter.find(pet.shelter_id)%>
<td><%= shelter.name %></td>
<td><%= shelter.phone %></td>
<td><%= shelter.email %></td>
<td><%= shelter.city %></td>
<td><%= shelter.zip %></td>
<td><%= form_for pet, :url => { :controller => "favorite_pets", :action => "create" }, :html => {:method => :post}, :remote => true do |f| %>
<%= f.hidden_field :id %>
<%= f.submit %>
<% end %>
</td>
</tr>
</tbody>
</table>
<%end%>
因此,每当有人点击f.submit
按钮时,javascript就会发挥作用,并在@pets数组中迭代第二个元素,只显示一个。
