两个ajax请求多次执行Rails控制器

Question

我有一个ajax函数故意连续两次运行（带有不同的参数），但是在Rails中，我接收的是8-14个服务器调用，分为两组参数

• 执行的次数似乎从请求变为请求。
• 我已经通过控制台消息确认Javascript正在执行两次。
• 两个ajax函数可以非常快速地发生，只需<1s。

的Ajax：

function receiveData(args) {
  var payload = args[0];
  var context = payload.id;
  var feedback = payload.value;

  $.ajax({
    url: "<%= generate_response_url(@program.id) %>/" + feedback
  }).done(function(output) {
    var arr = JSON.parse(output);
  });
}

路线：

get 'requests/generate_response/:program_id' => 'requests#generate_response', as: 'generate_response'

请求控制器：

before_action :require_user

def generate_response
  ...some data processing...
  render text: @message
end

服务器日志：

# Received happens 4-7 times then Complete happens 4-7 times
