如何将模型中的占位符文本添加到MVC视图中？ [英] How do I add placeholder text from the model into a MVC view?

问题描述

我有一个模型：

[DataType(DataType.EmailAddress)]
[DisplayFormat(ConvertEmptyStringToNull = true)]
[Display(Prompt = "Email Address")]
public string Email { get; set; }

我试图让提示显示在结果文本框的占位符文本中具有以下内容：

I am trying to get the "prompt" to show in the placeholder text of the resulting text box with the following:

@Html.EditorFor(model => model.Email, 
new { htmlAttributes = new { @class = "form-control input-md",
placeholder = @ViewData.ModelMetadata.Watermark } })

当我查看生成的HTML时，我只在输入标记中获得占位符。根据我所读的ViewData.ModelMetadata.Watermark应该工作。获取此占位符文本的正确方法是什么？

When I view the generated HTML I only get "placeholder" in the input tag. According to what I have read ViewData.ModelMetadata.Watermark should work. What is the correct way to get this placeholder text in place?

推荐答案

这解决了我的问题：

@Html.EditorFor(model => model.Email, new { htmlAttributes = 
new { @class = "form-control input-sm", 
placeholder = @Html.DisplayNameFor(m=>m.Email) } })

这样做的代码是

placeholder = @Html.DisplayNameFor(m=>m.Email)
