This is My Controller:

{
    $username = Input::get('username');
    $users = DB::table('user')
               ->where('username', $username)
               ->first(); 
    if ( $users !== null )

          //alert(username);
          $.ajax({
                type:"post",
                 dataType: "json",
                url :"{{URL::to('test/name') }}",

                    }

ajax is not response to the controller this is my problem

This is because you need to send json using the response() method from the controller to your view file.

Try out this way:

Controller:

public function name(Request $request)
{
    // your validation logic ..

    $userFound = User::find($request->input('username'))

    if($userFound !== null) {
        return response([
            'status'  => 'failed',
            'message' => 'User Not Found'
        ]);
    }

    return response([
        'status'  => 'success',
        'message' => 'User Found'
    ]);
}

And then update your success method of AJAX handler:

$.ajax({
    // ..

    success: function(receivedData) {
        console.log(receivedData);
    }

    // ..

});
