How can I use placeholder attribute with Html.EditorFor?
提问by caj
I want to use the placeholder attribute in the Html.EditorFor so I did just like in the first answer: Html5 Placeholders with .NET MVC 3 Razor EditorFor extension?
我想在 Html.EditorFor 中使用 placeholder 属性，所以我就像在第一个答案中一样：Html5 Placeholders with .NET MVC 3 Razor EditorFor extension?
But in the final part, I don't have the EditorTemplates folder so I created it and when I tried to create the string.cshtml view I couldn't because the name "string" is reserved so I chose stringg.cshtml instead and it didn't work! Do I have to change the name elsewhere in my program? I did exactly like the answer...
但在最后一部分，我没有 EditorTemplates 文件夹，所以我创建了它，当我尝试创建 string.cshtml 视图时我不能，因为名称“string”被保留，所以我选择 stringg.cshtml 而不是没用！我是否必须在程序中的其他地方更改名称？我确实很喜欢这个答案......
Thank you!
谢谢！

Upgrade to MVC 5.1 and you can use HTML attributes in EditorFor:
升级到 MVC 5.1，您可以在 EditorFor 中使用 HTML 属性：
@Html.EditorFor(m => m.variable, new { htmlAttributes = new { placeholder = "Your Placeholder Text" } })

@Html.EditorFor(model => model.members_ssn, new { htmlAttributes = new { @class = "form-control", placeholder = "Your Example Here" } })

This works for MVC 5.
这适用于 MVC 5。
In my case i was looking to set the placeholder from the model metadata, like this:
就我而言，我希望从模型元数据中设置占位符，如下所示：
@Html.EditorFor(model => model.name, new { htmlAttributes = new { @class = "form-control", placeholder = Html.DisplayNameFor(x => x.name) } })

When using TextBoxForor TextAreaForrather than EditorFor, use only the inner key-value pair from @Medo's answer, since the method directly expects an htmlAttributes object:
使用TextBoxFororTextAreaFor而不是 时EditorFor，仅使用@Medo 答案中的内部键值对，因为该方法直接需要一个 htmlAttributes 对象：
@Html.TextBoxFor(m => m.variable, new { placeholder = "Your Placeholder Text" })
(I realize this is tangential to the original question, but having this here would have helped me when I landed on this page earlier, looking for an answer to how to add placeholder text to an Html.TextAreaFor!)
（我意识到这与原始问题无关，但是当我早些时候登陆此页面时，将其放在此处会对我有所帮助，寻找如何将占位符文本添加到Html.TextAreaFor！）

Use some jquery, eg: $("#FirstName").attr("placeholder", "Do not type name - use Search button");
使用一些 jquery，例如： $("#FirstName").attr("placeholder", "Do not type name - use Search button");
