我的输入元素有问题，它有一个空值。我可以删除input元素吗？有什么办法吗谢谢。这是问题的图片

我可以删除带有空值的输入文本吗？
我使用js和 AJAX 来调用数据库中的这些值。这是我的脚本文件

showAllQuestions();

//function to get data
function showAllQuestions(){
    $.ajax({
        type: 'ajax',
        url: '<?php echo base_url() ?>teachers/showQuestions',
        async: false,
        dataType: 'json',
        success: function(data){
            var html = '';
            var i;
        for(i=0; i<data.length; i++){
            html +='<div class="card">'+
                        '<div class="card-header">'+
                            '<h4>Multiple Choice</h4>'+
                            '</div>'+
                            '<div class="card-body">'+
                                '<form>'+

                                        '<input type="text" class="form-control" name="choice2" value="'+data[i].choice2+'" aria-describedby="inputGroup-sizing-sm" required>'+

                                    '</div>'+
                                '</form>'+
                            '</div>'+
                        '</div>';
                }

                $('#showdata').html(html);
            },
            error: function(){
                alert('Could not get Data from Database');
            }
        });
}

为了展示，我用div标签将它括起来

<div id="showdata"></div>
