asp.net-core - <textarea> 与 "asp-for="一起时不显示内部文本

Question

这会在文本区域内显示“你好”:

@model PlannerViewModel
@{
    ViewData["Title"] = "Test";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Test</h2>
<form method="post">
    <div class="border rounded">
        <textarea class="form-control MyTextArea" rows="4">Hello there</textarea>
    </div>
</form>

这不会在文本区域内显示“你好”:

@model PlannerViewModel
@{
    ViewData["Title"] = "Test";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Test</h2>
<form method="post">
    <div class="border rounded">
        <textarea class="form-control MyTextArea" rows="4" asp-for="EditShutdown.Comments_Operations">Hello there</textarea>
    </div>
</form>

如您所见，唯一的区别是“asp-for”的存在。难道我做错了什么？有什么解决方法吗？

Answer 1

要解决这个烦人的事件，您可以使用;

@Html.IdFor

和

@Html.NameFor

例子;

<textarea id="@Html.IdFor(m => m.EditShutdown.Comments_Operations)" name="@Html.NameFor(m => m.EditShutdown.Comments_Operations)">Hello there</textarea>
