【问题描述】:
我正在尝试在我的 Rails 应用程序中使用 AJAX 和 jQuery,并且我使用了 after jQuery 方法。
当我点击新帖子链接时,我希望它消失,并在点击新帖子按钮后形成部分显示:
# here's the link from index.html.erb
<%= link_to 'New Post', new_post_path, id: 'new-post', remote: true %>
和后控制器
class PostsController < ApplicationController
before_action :set_post, only: [:show, :edit, :update, :destroy]
# GET /posts
# GET /posts.json
def index
@posts = Post.all
end
# GET /posts/1
# GET /posts/1.json
def show
end
# GET /posts/new
def new
@post = Post.new
end
# GET /posts/1/edit
def edit
end
# POST /posts
# POST /posts.json
def create
@post = Post.new(post_params)
respond_to do |format|
if @post.save
format.html { redirect_to @post, notice: 'Post was successfully created.' }
format.json { render :show, status: :created, location: @post }
format.js
else
format.html { render :new }
format.json { render json: @post.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /posts/1
# PATCH/PUT /posts/1.json
def update
respond_to do |format|
if @post.update(post_params)
format.html { redirect_to @post, notice: 'Post was successfully updated.' }
format.json { render :show, status: :ok, location: @post }
else
format.html { render :edit }
format.json { render json: @post.errors, status: :unprocessable_entity }
end
end
end
# DELETE /posts/1
# DELETE /posts/1.json
def destroy
@post.destroy
respond_to do |format|
format.html { redirect_to posts_url, notice: 'Post was successfully destroyed.' }
format.json { head :no_content }
format.js
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_post
@post = Post.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def post_params
params.require(:post).permit(:subject, :descripion)
end
end
和 new.js.erb
$('#new-post').hide().after('<%= j render partial: 'posts/form' %>');
我安装了 jQuery gem 并将其包含在 application.js 中,我注意到 hide 方法没有 after 正常工作
//= require rails-ujs
//= require jquery
//= require jquery_ujs
//= require activestorage
//= require turbolinks
//= require_tree .
我做错了什么?
