如何使用 EditorFor 禁用输入字段的自动完成功能?
<%= Html.EditorFor(product => product.Name) %>
我需要生成的输出设置 autocomplete="off" 属性。
我缺少什么?
编辑: 我正在寻找 EditorFor 的扩展方法,它接受属性的键/值字典,因此我可以这样调用它: <%= Html.EditorFor(product => product.Name, new { autocomplete = " off" } ) %>
需要调整一下
public static MvcHtmlString LabelFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression, object htmlAttributes) {
return LabelFor(html, expression, new RouteValueDictionary(htmlAttributes));
}
public static MvcHtmlString LabelFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression, IDictionary<string, object> htmlAttributes)
{
ModelMetadata metadata = ModelMetadata.FromLambdaExpression(expression, html.ViewData);
string htmlFieldName = ExpressionHelper.GetExpressionText(expression);
string labelText = metadata.DisplayName ?? metadata.PropertyName ?? htmlFieldName.Split('.').Last();
if (String.IsNullOrEmpty(labelText))
{
return MvcHtmlString.Empty;
}
TagBuilder tag = new TagBuilder("label");
tag.MergeAttributes(htmlAttributes);
tag.Attributes.Add("for", html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldId(htmlFieldName));
tag.SetInnerText(labelText);
return MvcHtmlString.Create(tag.ToString(TagRenderMode.Normal));
}
这里是针对LabelFor完成的,但是针对EditorFor Edit2 : 我意识到它不能命名为 EditorFor,因为已经存在一个接受匿名类型的重写 EditorFor,请参见此处 http://msdn.microsoft.com/en-us/library/ff406462.aspx..无论如何,我们可以以不同的方式命名它,没什么大不了的。
<%= Html.EditorFor(product => product.Name) %>
I need the generated output to have autocomplete="off" attribute set.
What I'm missing?
Edit:
I'm looking an extension method for EditorFor that accepts key/value dictionary for attributes, so I can call it like this: <%= Html.EditorFor(product => product.Name, new { autocomplete = "off" } ) %>
Here it is done for LabelFor, but it is needed to be adjusted for EditorFor
public static MvcHtmlString LabelFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression, object htmlAttributes) {
return LabelFor(html, expression, new RouteValueDictionary(htmlAttributes));
}
public static MvcHtmlString LabelFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression, IDictionary<string, object> htmlAttributes)
{
ModelMetadata metadata = ModelMetadata.FromLambdaExpression(expression, html.ViewData);
string htmlFieldName = ExpressionHelper.GetExpressionText(expression);
string labelText = metadata.DisplayName ?? metadata.PropertyName ?? htmlFieldName.Split('.').Last();
if (String.IsNullOrEmpty(labelText))
{
return MvcHtmlString.Empty;
}
TagBuilder tag = new TagBuilder("label");
tag.MergeAttributes(htmlAttributes);
tag.Attributes.Add("for", html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldId(htmlFieldName));
tag.SetInnerText(labelText);
return MvcHtmlString.Create(tag.ToString(TagRenderMode.Normal));
}
Edit2:
I realized it can't be named EditorFor because there already exists an overridden EditorFor that accepts an anonymous type, see here http://msdn.microsoft.com/en-us/library/ff406462.aspx.. anyway, we can name it differently, no biggies.

您需要使用自定义模板来生成带有该属性的输入元素,或者您可以向页面添加一些 javascript 以在客户端添加属性。
然后在 Shared/EditorTemplates 中,您需要一个 NoAutocompleteTextBox.ascx 来定义
或,以 jQuery 方式在所有文本输入上设置它
You'll need to use use a custom template that generates the input element with the attribute or you could add some javascript to the page to add the attribute client-side.
Then in Shared/EditorTemplates you need a NoAutocompleteTextBox.ascx that defines
or, the jQuery way, to set it on all text inputs
