Question

我是Laravel 5.6的新手，并且使用Ajax for CRUD进入数据库，当我尝试从我的模态中插入数据时，它不起作用。在迁移文件中，我更改了默认＆＃34; id＆＃34;到＆＃34; asset_category_id＆＃34;并在模型类中保护它，所以在我的数据库中，列是asset_category_id，category，created_at和updated_at。

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Asset_category;
use Illuminate\Support\Facades\Response;
use Illuminate\Validation\Validator;
use Illuminate\Support\Facades\Input;
use App\Http\Requests;

class Asset_categoriesController extends Controller
{

    public function index(){
        $asset_categories = Asset_category::all();
        return view('/asset_category/index', compact('asset_categories'));
    }

    public function addCategory(Request $request){
        $rules = array(
            'category' => 'required'
        );
        $validator = Validator::make(Input::all(), $rules);
        if ($validator->fails())
            return response::json(array('errors'=> $validator->getMessageBag()->toarray()));

        else{
            $asset_categories = new Asset_category;
            $asset_categories->category = $request->category;
            $asset_categories->save();
            return response()->json($asset_categories);
        }
    }
}

提前感谢您提出任何建议。

Answer 1

首先，您将csrf令牌放在错误的位置。它应该在form标记之下（它将成为名为_token的隐藏输入字段。如果没有，这很可能会在以后给您419错误。

其次，您可能想稍微更改点击功能：

$(‘#add’).on(‘click’, function (e) {
  e.preventDefault()
  // put your ajax code after this
});

第三，如果在“网络”选项卡的后端发生了某些事情，您始终可以看到错误。这会给你更多提示。

希望这有帮助。

Answer 2

更改按钮输入=＆＃34;提交＆＃34; 到输入=＆＃34;按钮＆＃34;

尝试：

$('form #add').on('click', function(){

                    >   alert('add');

 })
