Question

我有一个相当旧的网站，我作为新职位的一部分继承了它 - 它是根据Laravel 4.1。*版本规范构建的。

我的问题是Response::json在响应中返回未定义的变量，使用标准的AJAX post方法，并且正确定义了所有CSRF和ajaxSetup（）。

application.blade.php

 $.ajax({
   type: 'POST', //This will always be a post method for the supplier chain check form.
   url: 'supply-us/application', //URL endpoint for the post form method: we'll set this to the controller function we're targeting.
   data: { 'companyName': values['companyName'] }, //This will carry the form data that is needed to be passed to the server.
   success: function (response) {
       console.log(response['companyName']); << THIS LINE RETURNS "undefined"

       console.log(typeof response) << THIS LINE RETURNS string
   },
   error: function (response) {
       console.log(response);
   },
 });

values [＆＃39; companyName＆＃39;]返回我在表单中输入的内容。以上＆＃34;回复＆＃34;简单的chucks回html - 所以我认为我的路线可能在AJAX url param中被错误定义或错误定义，也许？以下是两条适用的路线：

routes.php文件

Route::controller('supply-us/application', 'ApplicationController');
Route::post('supply-us/application', 'ApplicationController@processSupplierApplication');

ApplicationController.php ：

<?php

use Illuminate\Http\Request;

class ApplicationController extends FrontController {
  public function getSupplierApplication() {
         return self::getPage('supply-us/application');
    }

  public function processSupplierApplication(Request $request) {
    if (Input::has('companyName')) {

       $this->companyName = Input::get('companyName');

       $data = [
          'success': true,
          'companyName': $this->companyName
       ];

       return response()->json($data);

    }

  }

}

任何专业提示将不胜感激！

在发布或获得结果时检查控制器中缺少的内容通常我遵循

<.form method="post" action="{{url('supply-us/application')}}".>
  {{csrf_field()}}  <.input type="text" name="companyName".>
  <./form.>

删除点试试这会帮助你在控制器中找到丢失的东西

在你的刀片中

  <.input type="text" name="companyName".>
  <./form.>

<.input type="text" name="companyName" id="companyName".>

 var company =  $('#companyName').val();
  $.ajax({
      type: 'POST',
      url: 'supply-us/application', 
      data: { 'Company':company,'_token': '{{ csrf_token() }}'  }, 
  success: function (response) {
    alert(data) // if this not work then try this alert(data.company)

  },
  error: function (response) {
   console.log(response);
 },
});

}

在Laravel 4.1中形成AJAX后响应周期。*
