如何设置@Html.EditorFor(model => model.location)的默认值？

Question

我尝试添加，new { @Value = "test“}，但失败了。

然后，我将模型修改为

    private string _location = string.Empty;

    public string location { get { return _location; } set { _location = value; } }

或者甚至将string.empty更改为我的默认文本，仍然失败。

有什么想法吗？Thx

你的解决方案很好，应该能行得通。但由于它没有，我认为您正在将null model传递给您的视图-在这种情况下，它永远不会得到评估位置，它的null。尝试将非空模型传递给视图。

return View(new LocationViewModel());

我用下面的源码尝试了你的解决方案，它对我来说很好。

模型

public class LocationViewModel
{
    private string _location = "test";

    public string Location
    {
        get { return _location; }
        set { _location = value; }
    }
}

动作

    public ActionResult Index()
    {
        ViewBag.Message = "Welcome to ASP.NET MVC!";
        return View(new LocationViewModel());
    }

视图

@model LocationViewModel

@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

@using (Html.BeginForm()) {
    @Html.ValidationSummary(true)
    <fieldset>
        <legend>Test</legend>

        <div class="editor-label">
            @Html.LabelFor(model => model.Location)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Location)
            @Html.ValidationMessageFor(model => model.Location)
        </div>

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>
