在浏览器上显示时，无法在此jquery代码行中编辑表单

Question

请注意，这不是我的代码，所以我不太明白。所以，这是用于触发divedit成员的html，如下所示

<div class="right-sidebar divedit-member">
    <div class="container-fluid">
        <br>
        <br>
        <div class="member-form"></div>
    </div>
</div>

然后这是我用来编辑编辑MEMBER的形式的脚本，只是想将输入标签name = s_year的值更改为其他如（1st，2nd，3rd）但是却无法设法这样做。当我编辑选项标签时，它仍然显示这个表格，我不想要..

$('.add_student').click(function()
{   
    $('.divedit-member').toggle(effect, options, duration);

    var form = '<form class="frm_add_student">\
                    <br/><br/><h4 class=""></h4>\
                    <hr>\
                    <div class="form-group">\
                        <label>School ID Number</label>\
                        <input type="number" name="sid_number" class="form-control" required autocomplete="off">\
                    </div>\
                    <div class="form-group">\
                        <label>First Name</label>\
