使用HtmlAttributes重载时TextAreaFor无法正常工作 [英] TextAreaFor Not Working When Using HtmlAttributes Overload

问题描述

由于某些原因，当我设置我的TextAreaFor样式属性(特别是width属性)时，它不起作用，我的意思是宽度没有改变，Id也没有改变:

For some reasons, when I set my TextAreaFor style properties specifically the width property, it is not working, what I mean is the width is not changing, and the Id is not changing as well:

 @Html.TextAreaFor(model => model.AdminSetting.Style, new { htmlAttributes = new 
 { @class = "form-control", @style = "width: 100%;", @id = "HelloWorld" } })

但是，如果我删除了 htmlAttributes 一词，并将其更改为该词，那么它将正常工作.我真的很奇怪为什么:

But if I remove the word htmlAttributes and change it to this then it working fine. I really wonder why:

@Html.TextAreaFor(model => model.AdminSetting.Style, 
new { @class = "form-control", @style = "width: 100%;", @id = "HelloWorld" })

除非我删除htmlAttributes声明并像这样声明它，否则我的TextAreaFor htmlAttributes 不能正常工作吗?

Is there reason why my TextAreaFor htmlAttributes not working unless I remove my declaration of htmlAttributes and declare it like this?

 new { @class = "form-control", @style = "width: 100%;", @id = "HelloWorld" })

代替这个吗?

new { htmlAttributes = new 
 { @class = "form-control", @style = "width: 100%;", @id = "HelloWorld" } })

我已经检查了文档，并且确定使用了正确的重载.

I've check the documentation, and I am sure that I am using the correct overload.

推荐答案

尝试如下所示:

@Html.TextAreaFor(m => m.AdminSetting.Style, 
    new { maxlength = 1000, @class = "form-control", @id = "HelloWorld" })

帮助者 Html.TextAreaFor ， Html.EditorFor ， Html.DisplayFor 都是独一无二的，因为它们被称为模板化的助手".它们不仅可以吐出一些 HTML 的定义位，还可以实际使用视图来确定其输出内容.这些视图分别称为编辑器模板"或显示模板".有关更多信息，请查看 Html.EditorFor和htmlAttributes .

The helpers, Html.TextAreaFor, Html.EditorFor, Html.DisplayFor are unique in that they're what's referred to as "templated helpers". Instead of just spitting out some defined bit of HTML, they're capable of actually using views to determine what their output will be. These views are referred to as "editor templates" or "display templates", respectively. For more information please have a look at Html.EditorFor and htmlAttributes.
