没有成功的POST数据html [英] no success POST data html

当我使用ajax发出请求时，我可以看到该发布值，但是当我看到控制台日志时，它会向我返回此消息---

以及在symfony Web调试工具栏中，我可以看到没有发出任何Ajax请求.

            <input  type="text" id= "contentSearch" name="contentSearch" >
        </div>
    <div class="form-group"><button type="submit" class="btn btn-default" id="submitSearch">
            Search
        </button></div>
</form>

这是我的JavaScript代码---

$(document).ready(function () {
$("#searchform").on('submit', function (e) {
    $.ajax({
        url: '/home',
        type: 'post',
        data: { contentSearch : $('#contentSearch').val()},
        success: function (data) {
            console.log(data)
        }
    });

   return false;
});
});
    </script>

控制器代码---

路由代码---

content:
    path:     /home
    defaults: { _controller: AdminBundle:Home:home }

控制器代码---

<?php
namespace AdminBundle\Controller;    
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;    
class homeController extends Controller {
/**
 * @param Request $request
 * @return Response
 */
 // route of /home
function homeAction(Request $request) {

 if ($request->getMethod() == 'POST') {
 $request = $request->request->get('contentSearch');
 // do something with the  $request
 $result;
}}
return $this->render('AdminBundle:Home:home.html.twig', array(
        'pageTitle' => 'my ajax',
        'menu' => $this->menu,
        'result' => $result
            )
);

有谁知道如何解决这个问题！！！！

Do any one knows how to solve this problem !!!!

推荐答案

您要发送两次表单.如果使用$(form).on('submit')设置函数，则在发送表单之前，它将执行您告诉它的任何操作.您必须添加event.preventDefault()

You are sending the form twice. If you set a function with $(form).on('submit') then BEFORE the form is sent, it will do whatever you tell it to. You have to add event.preventDefault()

$(form).on('submit',function(event){
  event.preventDefault()
  // Do Ajax
})

并确保返回带有回声的Ajax响应.

And be sure to return your Ajax response with echo.
