i send Answer the request ajax to file blade.php :

    public function GetSubCategory($category_id){
$sub="test";
        return response()->json($sub);


    }

Now I want to display the answer of the request.

How can I display it? (in file blade.php)

i want display variable "$sub" in file blade.php

I found the solution.

for display the answer of the request in file blade.php , we can use this cod:

controller

    public function GetSubCategory(){

        return response()->json(['success' => 'ok']);


    }

 

blade.php:

<span id="test"></span>
Document.getElementById('test').innerText=response.success
