laravel如何使用ajax获取数据库值？

Question

I want to post this form to Controller using ajax.

<form class="delete_confirm" action="{{ route('comment.delete_confirm', $mypage->id) }}">
  <input type="hidden" name="_token" value="{{ csrf_token() }}">
  <input type="password" name="pass_con" placeholder="비밀번호를 입력하세요.">
  <input type="submit" class="pass_submit" value="확인">
</form>

JS

$del_conForm.on('submit', function(){

        $.ajax({
            url: 'comment/{id}',
            type: 'post',
            data: $(this).serialize(),
            success: function(res){
                if (!res) {
                    alert('not correct');
                    return false;
                }
                else{
                    if (confirm("Click OK to continue?")) {
                        $delForm.submit();
                    }
                }
            }
        });

    });

I want to know $mypage->id in HTML form is also submit controller.

Controller

public function delete_confirm($id) {

    $mypage = mypage::findOrFail($id);

    $password = $mypage->password;

    $data = Input::get('pass_con');

    if ($data == $password) {
        return 'suc';
    }else{
        return false;
    }
}

Route

Route::get('comment/{id}', ['as'=>'comment.delete_confirm', 'uses'=>'MyPageController@delete_confirm']);
Route::post('comment/{id}', ['as'=>'comment.delete_confirm', 'uses'=>'MyPageController@delete_confirm']);

Request::ajax() part is work successfully, but $password returns nothing. Can controller delete_confirm method receive $id ?

Try this :

$del_conForm.on('submit', function(){
    url = $(this).attr("action");
    $.ajax({
        url: url,
        type: 'post',
        dataType : 'json'
        data: $(this).serialize(),
        success: function(res){
            if (!res.status) {
                alert('not correct');
                return false;
            }
            else{
                if (confirm("Click OK to continue?")) {
                    $delForm.submit();
                }
            }
        }
    });

});

// your controller code should look like this

public function delete_confirm($id) {

    $mypage = mypage::findOrFail($id);

    $password = $mypage->password;

    $data = Input::get('pass_con');
    $response = array();
    if ($data == $password) {
       $response['status'] = true;
    }else{
       $response['status'] = false;
    }
    return response()->json($response);
}
