问题描述
我将 Rails 4.0.2 与 jquery-rails (3.1.0) 和 jquery-ui-rails (4.1.1) gems 一起使用.我正在尝试将 Autocomplete 添加到搜索表单(使用 引导程序 3.1.0):
<%= text_field_tag :query, params[:query], id: "navbar-search-input", class: 'form-control', placeholder: 'Product name.....' %>
<%= button_tag(type: 'submit', id: 'navbar-search-btn', class: 'btn btn-default') do %><i class='fa fa-search fa-fw'></i>搜索<%结束%><%结束%>
这是我的应用程序 JS 和 CSS 文件:
application.js
//= 需要 jquery//= 需要 jquery_ujs//= 需要 jquery.ui.autocomplete//= 需要涡轮链接//= require_tree .准备就绪;准备好 =(函数(){$('a[href="' + this.location.pathname + '"]').parent().addClass('active');$("#navbar-search-input").autocomplete({来源:'/products/autocomplete.json',});});$(文件).ready(ready);$(document).on('page:load', ready);
application.css.scss
*= 需要引导程序*= font-kit-rails/ubuntu*= 需要 jquery.ui.autocomplete*= require_self*= require_tree .
比我的控制器和自动完成的路由:
class ProductsController
routes.rb
资源:产品做收藏做获得自动完成"结尾结尾
现在有了所有这些,我的 json 文件和我在
/products/autocomplete.json
中的所有产品都在那里.问题是如果我输入任何内容,它会给我一个空白的下拉列表,如果我点击下拉列表的任何区域,它将重置搜索表单字段.你知道如何让它发挥作用吗?
编辑
注意:我有一个名为 Rice
的产品在 2014-03-19 10:06:51 -0400 开始 GET "/products/autocomplete.json?term=ric" for 127.0.0.1由 ProductsController#autocomplete 处理为 JSON参数:{"term"=>"ric"}Product Load (0.9ms) SELECT "products".* FROM "products" WHERE (name ILIKE '%%') ORDER BY "products"."name" ASC在 16ms 内完成 200 OK(查看:14.3ms | ActiveRecord:0.9ms | Search:0.0ms)
解决方案 def autocomplete@products = Product.order(:name).where("name LIKE ?", "%#{params[:term]}%")response_to do |格式|格式.html格式.json {渲染 json:@products.map(&:name).to_json}结尾结尾
I'm using Rails 4.0.2 with jquery-rails (3.1.0) and jquery-ui-rails (4.1.1) gems. I'm trying to add Autocomplete to the search form (using Bootstrap 3.1.0):
<%= form_tag products_path, method: :get, class: 'navbar-form navbar-left' do %>
<div class='form-group'>
<%= text_field_tag :query, params[:query], id: "navbar-search-input", class: 'form-control', placeholder: 'Product name.....' %>
</div>
<%= button_tag(type: 'submit', id: 'navbar-search-btn', class: 'btn btn-default') do %>
<i class='fa fa-search fa-fw'></i> Search
<% end %>
<% end %>
Here are my application JS and CSS files:
application.js
//= require jquery
//= require jquery_ujs
//= require jquery.ui.autocomplete
//= require turbolinks
//= require_tree .
var ready;
ready = (function() {
$('a[href="' + this.location.pathname + '"]').parent().addClass('active');
$("#navbar-search-input").autocomplete({
source: '/products/autocomplete.json',
});
});
$(document).ready(ready);
$(document).on('page:load', ready);
application.css.scss
*= require bootstrap
*= font-kit-rails/ubuntu
*= require jquery.ui.autocomplete
*= require_self
*= require_tree .
Than my controller and route for the autocompletion:
class ProductsController < ApplicationController
def autocomplete
@products = Product.order(:name)
respond_to do |format|
format.html
format.json {
render json: @products.where("name ILIKE ?", "%#{params[:q]}%")
}
end
end
routes.rb
resources :products do
collection do
get 'autocomplete'
end
end
Now with all of this, my json file with all of my products at /products/autocomplete.json
are there. The problem is if I type in anything, it gives me a blank dropdown and if I click on any area of the dropdown it will reset the search form field. Do you know how to get this to work?
EDIT
NOTE: I have a Product named Rice
Started GET "/products/autocomplete.json?term=ric" for 127.0.0.1 at 2014-03-19 10:06:51 -0400
Processing by ProductsController#autocomplete as JSON
Parameters: {"term"=>"ric"}
Product Load (0.9ms) SELECT "products".* FROM "products" WHERE (name ILIKE '%%') ORDER BY "products"."name" ASC
Completed 200 OK in 16ms (Views: 14.3ms | ActiveRecord: 0.9ms | Search: 0.0ms)
解决方案 def autocomplete
@products = Product.order(:name).where("name LIKE ?", "%#{params[:term]}%")
respond_to do |format|
format.html
format.json {
render json: @products.map(&:name).to_json
}
end
end
