asp中加入html标签,asp.net-mvc-3 – 在html标签中添加html输入

为什么你不能用@Html创建这些.如果你编写自己的扩展方法(见下文),应该这样做吗？

public static class HtmlHelperExtensions

{

public static MvcHtmlString MyCheckBoxFor(this HtmlHelper htmlHelper, Expression> expression, object htmlLabelAttributes = null, object htmlCheckBoxAttributes = null)

{

var checkbox = htmlHelper.CheckBoxFor(expression, htmlCheckBoxAttributes);

var labelTag = new TagBuilder("label");

labelTag.AddCssClass("checkbox");

labelTag.MergeAttributes(HtmlHelper.AnonymousObjectToHtmlAttributes(htmlLabelAttributes));

labelTag.InnerHtml = checkbox.ToString();

return new MvcHtmlString(labelTag.ToString());

}

}

编辑：

这个修订版本怎么样这正是标签所做的.

public static class HtmlHelperExtensions

{

public static MvcHtmlString MyCheckBoxFor(this HtmlHelper htmlHelper, Expression> expression, object htmlLabelAttributes = null, object htmlCheckBoxAttributes = null)

{

var checkbox = htmlHelper.CheckBoxFor(expression, htmlCheckBoxAttributes);

var labelTag = new TagBuilder("label");

var checkboxName = ExpressionHelper.GetExpressionText(expression);

labelTag.AddCssClass("checkbox");

labelTag.MergeAttributes(HtmlHelper.AnonymousObjectToHtmlAttributes(htmlLabelAttributes));

labelTag.InnerHtml = checkbox.ToString() + LabelHelper(ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData), checkboxName);

return new MvcHtmlString(labelTag.ToString());

}

private static MvcHtmlString LabelHelper(ModelMetadata metadata, string fieldName)

{

string labelText;

var displayName = metadata.DisplayName;

if (displayName == null)

{

var propertyName = metadata.PropertyName;

labelText = propertyName ?? fieldName.Split(new[] { '.' }).Last();

}

else

{

labelText = displayName;

}

if (string.IsNullOrEmpty(labelText))

{

return MvcHtmlString.Empty;

}

return new MvcHtmlString(labelText);

}

}

我应该注意,使用MVC 4有一个DisplayNameFor Helper,所以整个标签业务可以简化一下.
