html ASP.NET Core 2.0将焦点设置在输入元素上

我有一个旧的ASP.NET核心MVC剃刀部分表单，有2个输入字段，我试图设置焦点在表单加载的第一个输入字段上，当用户改变值时，我想然后改变焦点到第二个输入框。这是我的第一个项目与ASP.NET核心2.0剃刀页工作。
问题是当我尝试使用HTML、Java或剃刀代码设置焦点时，它不起作用。我希望有人能看到我哪里出错了。提前谢谢你。

// shows the partial form
                $.getJSON("/orders/orderlist/conn", function (conn) {
                    if (conn == "true") {
                        $('#orderstartmodal').modal('show');
                        $('#orderstartmodal').on('shown.bs.modal', function () {
                             $('#orderstartpick').focus();
                          })
                    }
                    else {
                        $('#noorderstartmodal').modal('show');  //{ backdrop: 'static', keyboard: false, show: true });
                    }
                });

**注意：**正如您所看到的，在您的code snippet中，我可以在加载模态时看到一个if conditional。您应该在加载模态后立即加载以下代码片段：

$('#orderstartmodal').on('shown.bs.modal', function () {
            $('#orderstartpick').focus();
        })

我尝试了HTML代码的焦点，Java代码，剃刀代码，但没有东西试图设置焦点输入一。
在这种情况下，你必须把你的focus script写在你的主视图中，而不是写在部分页面中。你可以做如下的事情：

输入焦点的脚本：

$(document).ready(function () {
        $(function () {
            $('#orderstartmodal').modal('show');

        });
        $('#orderstartmodal').on('shown.bs.modal', function () {
            $('#orderstartpick').focus();
        })
     
        $("#orderstartpick").change(function () {
            $('#orderstartdrop').focus();
        });
            
 });

**注意：**此脚本需要放在您的主页下面，您已经调用了您的部分视图。正如您所看到的，我使用了change和onmouseover都将执行。但是，根据您的描述，您需要on change事件，然后将焦点设置到下一个input box，即：$('#orderstartdrop').focus();
输出：

**注意：**由于您还没有分享您的主页详细信息，所以我刚刚加载了下面的另一个页面。
