Ajax结合弹框实现增删改

1. 在下面这个视图中我们利用ajax弹框进行操作

<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#roleModal" onclick="add();">
    新增
</button>
<table class="table table-bordered">
    <thead>
        <tr>
            <th>名称</th>
            <th>备注</th>
            <th>修改</th>
            <th>删除</th>
        </tr>
    </thead>
    <tbody>
        @foreach (var item in Model)
        {
   
   
            <tr>
                <td>@item.Name</td>
                <td>@item.Remark</td>
                <td>
                    <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#roleModal" onclick="edit(@item.ID)">
                        修改
                    </button>
                </td>
                <td>
                    <button type="button" class="btn btn-primary" onclick="del(@item.ID)">
                        删除
                    </button>
                </td>

            </tr>
        }
    </tbody>
</table>

2.利用bootstrap样式单击新增、修改弹出模态框

<div class="modal fade" id="roleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class
