javascript - Asp.NET MVC 中的模态

Question

我有一个 Asp.NET MVC 应用程序，我尝试使用模式来更新数据，我有两个模式用于注册和更新，注册正常，但更新不起作用，当单击时在“Alterar”按钮上，需要打开一个填充了数据的模式，我尝试使用 JavaScript 来执行此操作。

有人可以帮助我吗？

我的 table

        {
            foreach(var sale in Model)
            {
                <tr>
                    <td>@Html.DisplayFor(model => sale.idProduct)</td>

要更改输入的值，您需要使用 val() :

<script type="text/javascript">
$(document).ready(function () {
    $('.update').on('click', function () {
        var $this = $(this);
        var idProduct = $this.data('id');
        var nameProduct = $this.data('name');
        var costProduct = $this.data('cost')
        var profitProduct = $this.data('profit')
        $('#nameProduct').val(nameProduct);
        $('#costProduct').val(costProduct);
        $('#profitProduct').val(profitProduct);
        $("#updateModal #form_update #idProduct").val(idProduct);
        $('#updateModal').modal();
    });
});
