为什么我在Rails中两次收到JQuery警报?

问题描述

我在删除链接上有一个jquery确认.当您单击链接时，确认弹出窗口就很好了，但是，当您单击确定"时，第二次弹出确认窗口.我不知道为什么.除了不必单击两次确定"之外，该方法还可以正常运行，并且帖子被删除.

I have a jquery confirmation on a delete link. The confirmation pops up just fine when you click on the link, however, it pops up a second time when you click 'OK'. I can not figure out why. Other than having to click 'OK' twice, the method works fine and the post gets deleted.

show.html.haml

%h1= @post.title
%p= @post.description

%p= link_to 'Back', root_path
%p= link_to 'Edit', edit_post_path
%p= link_to 'Delete', @post, method: :delete, data: { confirm: 'Are you sure you want to delete this Post?' }

posts_controller.rb

class PostsController < ApplicationController
  before_action :find_post, only: %i[show edit update destroy]
.
.
.
  def destroy
      @post.destroy
      redirect_to root_path, notice: 'Post successfully deleted.'
  end
.
.
.
  def find_post
      @post = Post.find(params[:id])
  end
end

application.js

//= require jquery
//= require jquery_ujs
//= require rails-ujs
//= require turbolinks
//= require_tree .

推荐答案

将jquery_ujs从application.js中删除，因为rails_ujs足以用于以后的rails版本.

remove jquery_ujs from your application.js as rails_ujs is enough for later rails version.
