[英]ruby on rails jquery not calling the right controller action
当我开始发布此问题时,我阅读了所有弹出的答案,但它们似乎无法解决我的问题。
我向控制器添加了一个名为get_results的新动作(除了通过脚手架创建的动作外),但是每次我更改选择菜单中的选择时,它都会引导我执行“ edit”动作,而不是“ get_results”,
这是js
<script type="text/JavaScript">
$(function(){
$('.menu_class').bind('change', function(){
$.ajax('#{:controller => "my_tests", :action => "get_results"}?param_one=' + $(this).val());
});
});
</script>
编辑:这是为我工作的js代码,感谢罗宾的回答如下:
<script type="text/JavaScript">
$(function(){
$('.menu_class').bind('change', function(){
$.ajax({
url: "<%= get_results_my_tests_url %>",
data: {
param_one: $(this).val()
}
});
});
});
</script>
这是我添加的操作(摘要)
def get_results
# some stuff goes here
respond_to do |format|
if @my_test.update_attributes(params[:my_test])
format.html
format.js
else
format.html { render :action => "update" }
format.json { render :json => @my_test.errors, :status => :unprocessable_entity }
end
end
end
我在我的routes.rb中添加了一条特定的路由
MyTests::Application.routes.draw do
resources :my_tests
get "home/index"
match '/my_tests/get_results' => 'my_tests#get_results', :as => :get_results
match ':controller(/:action(/:id(.:format)))'
root :to => 'home#index'
end
编辑:这是为我工作的路由配置,感谢罗宾的回答如下:
resources :my_tests do
collection do
get :get_results
end
end
耙路给我这个
my_tests GET /my_tests(.:format) {:action=>"index", :controller=>"my_tests"}
POST /my_tests(.:format) {:action=>"create", :controller=>"my_tests"}
new_my_test GET /my_tests/new(.:format) {:action=>"new", :controller=>"my_tests"}
edit_my_test GET /my_tests/:id/edit(.:format) {:action=>"edit", :controller=>"my_tests"}
my_test GET /my_tests/:id(.:format) {:action=>"show", :controller=>"my_tests"}
PUT /my_tests/:id(.:format) {:action=>"update", :controller=>"my_tests"}
DELETE /my_tests/:id(.:format) {:action=>"destroy", :controller=>"my_tests"}
home_index GET /home/index(.:format) {:action=>"index", :controller=>"home"}
get_results /my_tests/get_results(.:format) {:action=>"get_results", :controller=>"my_tests"}
/:controller(/:action(/:id(.:format)))
root / {:action=>"index", :controller=>"home"}
那么,为什么总是将我引导到“编辑”操作而不是“ get_results”呢?
尝试这个:
您的JavaScript应该是
<script type="text/JavaScript">
$(function(){
$('.menu_class').bind('change', function(){
$.ajax({
url: "<%= get_results_my_tests_url %>",
data: {
param_one: $(this).val()
}
});
});
});
</script>
您的路线:
resources :my_tests do
# if "/my_tests/get_results" is really what you want
collection do
get :get_results
end
#if "/my_tests/1/get_results" is what you actually want
#it would make more sense, especially because you have @my_test in the controller
member do
get :get_results
end
end
$.ajax('#{:controller => "my_tests", :action => "get_results"}?param_one=' + $(this).val());
由于该代码段中没有ERB,因此上述内容只是JS中的普通字符串。 它将构造一个URL,如:
http://example.com/the_current_page#{:controller => "my_tests", :action => ....
而网址中#
之后的部分将不会发送到服务器。 在网络面板中查看一下,应该清楚发生了什么。
