在 Laravel 中，如何简单地将数据从 js 传递到 controller 返回查看？

Question

I basically need to click a button in my blade view that triggers a function in my js file, that then sends some values to a controller and back to the the view. Using the code below, do I need to be creating a route for this? Thanks

view:
<div id="sendAsEmailTest">SEND AS EMAIL TEST</div>


js:
$('#sendAsEmailTest').on('click', function () {
  $.ajax({
    headers: {
       'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
     },
    type: "POST",
    url: "FormController/TestFunction",
    data: { name: "John" }
  }).done(function( msg ) {
    // alert( "Data Saved: " + msg.name );
  });
});


FormController:
public function TestFunction(Request $request)
     {
       return view('calculator.calculator',
         [
         'testdata' => $request,
         ]
       );
     }

Answer 1

thanks for the help @ßãlãjî. had to adjust things slightly, but seems to be working fine now:

js:
$('#sendAsEmailTest').on('click', function () {
  $.ajax({
    headers: {
       'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
     },
    type: "POST",
    url: "/formControllertestfunction",
    data: { name: "John" }
  }).done(function( msg ) {
    // alert( "Data Saved: " + msg.name );
  });
});

route:
Route::post('formControllertestfunction','FormController@TestFunction')->name('formControllertestfunction');

controller:
public function TestFunction(Request $request) {
         return view('calculator.back',
           [
             'displayName' => $request->name ,
           ]);
       }

Answer 2

your route should be post

route::post('formController/testfunction'@'FormController@TestFunction')

just

 public function TestFunction(Request $request)
         {
         dd($request->name)<---- you get your attribute  value here
         }
then correct

js:

$('#sendAsEmailTest').on('click', function () {
  $.ajax({
    headers: {
       'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
     },
    type: "POST",
    url: "formController/testfunction",<------------------all letters in small
    data: { name: "John" }
  }).done(function( msg ) {
    // alert( "Data Saved: " + msg.name );
  });
});
