Question

我在数据库中有一个数据，其中2个表称为注册，问题是我需要根据问题显示注册表数据question_schedul（被视为状态）= 1或2，在我的索引页面中有一个下拉列表包含24个小时和15天它与question_schedul（状态）有关。当我选择24小时时，我需要显示与所选状态相对应的数据

Javascript code for dropdown
  $(function () {

        $("#dropselect").change(function () {
            let $value;
            if ($(this).val() === "24Hours") {
                $value = $(this).val();
                $.ajax({
                    type: 'GET',
                    url: '{{\Illuminate\Support\Facades\URL::to('tracks24or15')}}',
                    data: {'dropselect': $value},
                    success: function (data) {
                        $('#listdetails').html(data);
                        // console.log(data);
                    }
                });

            }
            else {
                if ($(this).val() === "15Days") {
                    $value = $(this).val();
                    $.ajax({
                        type: 'GET',
                        url: '{{\Illuminate\Support\Facades\URL::to('tracks24or15')}}',
                        data: {'dropselect': $value},
                        success: function (data) {
                            $('#listdetails').html(data);
                            // console.log(data);
                        });
                    }
                else
                    {
                        alert('Select Status');
                    }

                    });
            });

具有功能的我的控制器

 public function tracks24or15(Request $request)
    {


        $register = DB::table('registrations')
            ->join('questions', 'registrations.registration_id', '=', 'questions.question_id')
            ->select('address', 'model', 'chassis', 'delivery_date')
            ->where([["questions.question_schedul", "=", 1] || ["questions.question_schedul", "=", 2] ])
            ->get();
        $output = "";
        $count = 1;
        foreach ($register as $key => $reg) {

            $output .= '<tr>' .

Answer 1

尝试更改你的js

更改网址

url：{{url（＆＃34; tracks24or15＆＃34;）}}

在ajax调用中添加数据类型 dataType：＆＃39; json＆＃39;，

由于你的两个ajax调用是相同的，我合并为一个

下拉列表的Javascript代码

$(function () {
        $("#dropselect").change(function () {
            let $value;
            if (($(this).val() === "24Hours") || ($(this).val() === "15Days")) {
                $value = $(this).val();
                $.ajax({
                    type: 'GET',
                    url: {{url("tracks24or15")}},
                    data: {'dropselect': $value},
                    dataType: 'json',
                    success: function (data) {
                        $('#listdetails').html(data);
                        // console.log(data);
                    }
                });

            }
            else
            {
                alert('Select Status');
            }
        });
    });
