C＃Razor - 显示注释值，其中循环值等于selectedIndex值 - 编程

I have a select list that looks like this:

我有一个如下所示的选择列表:

<select class="form-control">
     <option>Select</option>
     <option value="2">Order</option>
     <option value="5">Delivery</option>
     <option value="6">PickUp</option>
     <option value="13">Quote</option>
</select>

Once a user selects an option, I would like to display a comment only where db_Type = the value of the selected option:

一旦用户选择了一个选项,我想只显示注释,其中db_Type =所选选项的值:

foreach (var note in Model.GetNotes)
    {
        <div class="current-note-container">
            <h5 class="note-comment"><b>Description:</b><br/> @note.db_Comment.Where(note.db_Type == /* Selected Index */)</h5>
        </div>
    }

I'm not really sure how I can accomplish this using razor, or how to mix javascript in to get the job done.

我不确定如何使用剃须刀完成此操作,或者如何混合使用javascript来完成工作。

This is not exact, but I'm think you're looking for something like this

这不是确切的,但我认为你正在寻找这样的东西

<select class="form-control" onchange="GetComment(this.value)">
     <option>Select</option>
     <option value="2">Order</option>
     <option value="5">Delivery</option>
     <option value="6">PickUp</option>
     <option value="13">Quote</option>
</select>

Add this to the script of your razor view

将其添加到剃刀视图的脚本中

function GetComment(ID)
{
    var parameters = {};

    parameters["ListID"] = ID;

    $.ajax
    ({
        type: "GET",
        data: parameters,
        url: "/MyController/GetComment",
        success: function (message) {
            $('#note-comment').val(message);
        },
        error: function () {
            alert("error");
        }
    });
}

And finally something like this to your controller

最后这个对你的控制器来说

[HttpGet]
public JsonResult GetComment(int ListID)
{
    return Json(Mylist[ListID].Comment);
}
