Question

I want to pass data from controller to jquery using json don't know where is the problem but fro the jquery code I think its working fine as I tested the success code but can't get back the result from controller

home.blade

    <form role="form" name="form_address" id="form_address" action="" method="POST"  enctype="multipart/form-data">
     {{ csrf_field() }}
  <input type="text" id="postal_code" onFocus="geolocate()">
  <input type="text" id="totaldistance"  onFocus="geolocate()">
 </form>
  <button id="save_address">Save</button>

 <script>
$("#save_address").click(function (e) {
$.ajaxSetup({
    headers: {
         'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
    }
   });

   e.preventDefault();
  var form = document.forms.namedItem("form_address");
  var formData = new FormData(form); 
  $.ajax({
     type: "get",
    url: 'Get_distance',
    contentType: false,
    data: formData, 
    processData: false,
    success: function(data) {
      $('#totaldistance').val(data.distance); 
    }
   });
  });

web.php

Route::post('Get_distance','HomeController@getdistance');

controller

public function getdistance(Request $request)
{
  $distance =$request->postal_code;

  return Response::json(array(
    'distance' => $distance,  
  ));
}

Answer 1

将您的ajax类型更改为POST ，因为您的路由类型是POST而不是GET 。

Answer 2

Your defined route in web.php is a POST request, but your Ajax method is set to GET request. Change web.php to a GET request for it to work. Make sure to provide an error function to catch any errors from server side.

Or vice versa, change Ajax request to POST since you already added the csrf setup.
