How to save data using ajax request in Laravel version 5.5 - php

Question

My ajax call:
$('#password_change_form').submit(function(e) {
e.preventDefault();
var saveThis = this;
$.ajax({
type: "POST",
url: "{{ url('/changepassword') }}",
data: $(saveThis).serialize(),
success: function(data) {
$("#password_change_form").trigger("reset");
alert(data);
}
});
}),
My Controller method:
public function changepassword(Request $request){
$user = Auth::guard()->user();
$request_data = $request->All();
$validator = $this->admin_credential_rules($request_data);
if($validator->fails()) {
$errors = $validator->errors();
$errors = json_decode($errors);
return response()->json([
'success' => false,
'message' => $errors
], 422);
} else {
$current_password = $user->password;
if(md5($request_data['password']) == $current_password) {
$user_id = $user->id;
$obj_user = User::find($user_id);
$obj_user->password = md5($request_data['new_password']);
$obj_user->save();
$msg = "password has been changed";
return response()->json(array('change_password'=> $msg), 200);
} else {
$error = array('error' => array('Heslo, které jste zadali, je neplatné.'));
return response()->json([
'modal_message_danger' , "Heslo, které jste zadali, je neplatné.",
'message' => $error
], 422);
}
}
}
When I hit the submit button on the popup form it shows me the HTML alert. I have also attached the screen shot of this alert:
Here my data is not saving. I am kind of confused about this problem. Please help me regarding this problem.
Your help will be highly appreciated!
Here is a screenshot of my alert:

The question is if your javascript in within your blade.php file if it's not in your blade.php you can't use the blade syntax:
url: "{{ url('/changepassword') }}",
the bracers or only valid within the blade template area not in your js just replace it with this
url: "/changepassword",
Further add check if you get any data from your javascript like this in your controller method
dd($request->all());
If it does output your the data you are trying to sent your ajax works if not it does not.
