这是我对StackOverflox的第一个问题（对此我感到非常紧张） 我在周末尝试了一些AJAx，但没有成功... 我关注了以下视频：https://www.youtube.com/watch?v=eJHHIcScqYA，并尝试按照我的代码进行操作。 我认为这和javascript ：（请原谅我的法语！）：
$(document).ready(function(){
$('#delete_beerlist').on("click", function(){
$.ajax({
url: '/beer_lists/' + this.parentElement.id,
type: 'DELETE',
succes: function(r){
}
});
});
});<h3> Pression </h3>
<% @draft_beers.each do |item| %>
<tr id='<%= item.id%>'>
<td> <%= Beer.find(item.beer_id).name %> - </td>
<td> Prix pinte: <%= item.pint_price %> - </td>
<td> Prix demi: <%= item.half_pint_price %> - </td>
<td> <%= link_to "modifier les prix", edit_beer_list_path(item.id) %> - </td>
<td id='delete_beerlist'>Supprimer</td>
</tr> </br>
<% end %>
<h3> Bouteille </h3>
<% @bottle_beers.each do |item| %>
<tr id='<%=item.id%>'>
<td> <%= Beer.find(item.beer_id).name %> -</td>
<td> Prix bouteille: <%= item.bottle_price %> -</td>
<td> <%= link_to "modifier le prix", edit_beer_list_path(item.id) %> </td> -
<td id='delete_beerlist'>Supprimer</td>
</tr> </br>
<% end %>
并且onClick在我的控制台中什么也没给出。我有gem'jquery-rails'，在我的application.js中需要'jquery3'，这让我很生气。 感谢您的帮助！
