>定义必须处理AJAX调用的操作的路由。例如。

AcmeHomeBundle_ajax_update_mydata:
  pattern:  /update/data/from/ajax/call
  defaults: { _controller: AcmeHomeBundle:MyAjax:updateData }

>从Home bundle定义MyAjax控制器中的操作。例如。

public function updateDataAction(){
  $request = $this->container->get('request');        
  $data1 = $request->query->get('data1');
  $data2 = $request->query->get('data2');
  ...
  //handle data
  ...
  //prepare the response,e.g.
  $response = array("code" => 100,"success" => true);
  //you can return result as JSON
  return new Response(json_encode($response)); 
}

>在您的Twig模板中准备您的AJAX电话，例如：

function aButtonPressed(){
    $.post('{{path('AcmeHomeBundle_ajax_update_mydata')}}',{data1: 'mydata1',data2:'mydata2'},function(response){
                    if(response.code == 100 && response.success){//dummy check
                      //do something
                    }
 
    },"json");    
}
 
$(document).ready(function() {     
  $('button').on('click',function(){aButtonPressed();});
});

您可以使用其他AJAX调用更改示例。
