我的单选按钮无法使用 ajax jquery 在 laravel 8 中自动保存数据

Question

有人可以帮助我编写代码吗？我的单选按钮无法使用 ajax jquery 在 laravel 8 中自动保存数据，而且我没有收到错误消息留言

我的控制器：Q_AnswersController

public function storeAns(Request $request)
    {
        
        $model = new Q_Answer;
        $model->user_id = Auth::id();
        $model->topic_id = $request->topic_id;
        $model->question_id = $request->question_id;
        $model->user_answer = $request->radio_ans;
        $model->answer = $request->answer;
        $topik = $request->topic_id;
        
        $model->save();
               
        return redirect('qanswers/'. $topik);
    }

这是我的路线：

Route::post('/storeAns',[Q_AnswersController::class, 'storeAns'])->name('storeAns');

这是我的 blade :

@foreach ($datas as $key=>$value)
                    <p>{{ $value->question }}</p>
                    <p><input type="radio" id="radio1" name="radio_ans" value="{{ $value->a }}"><label>&nbsp;&nbsp;{{ $value->a }}</label></p>
                      <p><input type="radio" id="radio2" name="radio_ans" value="{{ $value->b }}"><label>&nbsp;&nbsp;{{ $value->b }}</label></p>
                        <p><input type="radio" id="radio3" name="radio_ans" value="{{ $value->c }}"><label>&nbsp;&nbsp;{{ $value->c }}</label></p>
                        <p><input type="radio" id="radio4" name="radio_ans" value="{{ $value->d }}"><label>&nbsp;&nbsp;{{ $value->d }}</label></p>
                        <p><input type="radio" id="radio5" name="radio_ans" value="{{ $value->e }}"><label>&nbsp;&nbsp;{{ $value->e }}</label></p>
                        <p><input type="radio" id="radio6" name="radio_ans" value="{{ $value->f }}"><label>&nbsp;&nbsp;{{ $value->f }}</label></p>
                        <input type="hidden" name="topic_id" class="form-control" readonly value="{{ $value->topic_id }}">
                        <input type="hidden" name="answer" class="form-control" readonly value="{{ $value->answer }}">
                        <input type="hidden" name="id" class="form-control" readonly value="{{ $value->id }}">
                        <input type="hidden" name="question_id" class="form-control" readonly value="{{ $datas->currentPage() }}">
                        <input type="hidden" name="user_id" class="form-control" hidden readonly value=" {{ Auth::id(); }} " >
                    @endforeach

这是我的脚本：

$(document).ready(function() {
        $('input[type="radio"]').click(function() {
            var user_id = $("#user_id").val();
            var topic_id = $("#topic_id").val();
            var question_id = $("answer").val();
            var answer = $("answer").val();
            var user_answer = $("radio_ans").val();
            $.ajax({
                headers: {
                    'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
                },
                url: "{{ url('qanswers.storeAns') }}",
                method: "POST",
                data:{
                    user_id:user_id,
                    topic_id:topic_id,
                    question_id:question_id,
                    answer:answer,
                    user_answer:user_answer
                } ,
                success: function(data) {
                    $('#alert').text('Data Inserted Successfully..');
                }
            });
        });
    });

非常感谢各位大侠帮忙，谢谢

Answer 1

您正在 ajax 请求和后端发送 user_answer 密钥，读取 $request->radio_ans 而不是 $request->user_answer。所以改变这一行：

 $model->user_answer = $request->radio_ans;

至

 $model->user_answer = $request->user_answer;

Answer 2

您使用 jquery 中的单选按钮名称获取单选按钮值但是这个语法给出的值是未定义的

var user_answer = $("radio_ans").val();

你可以试试这个 -

var user_answer = $("input[name=radio_ans]:checked").val();
