我要求我实施sitecore WFFM来创建表单。该页面包含带有Placeholder属性的HTML输入标记。我必须将WFFM SingleLineInput框渲染为具有占位符属性的输入标记。我该怎么办?
我知道SingleLineText
dll中定义了Sitecore.Form.Web.UI.Controls
类。

如果您使用的是WFFM的MVC版本,则需要按照批准的答案
中的说明添加以下内容1-创建课程
public interface IPlaceholderField
{
string PlaceHolder { get; set; }
}
[ValidationProperty("Text")]
public class SingleLineText : Sitecore.Form.Web.UI.Controls.SingleLineText, IPlaceholderField
{
[VisualCategory("Custom Properties")]
[VisualProperty("Placeholder", 2)]
[DefaultValue("")]
public string PlaceHolder { get; set; }
protected override void OnInit(EventArgs e)
{
// Set placeholder text, if present
if (!string.IsNullOrEmpty(PlaceHolder))
{
textbox.Attributes["placeholder"] = PlaceHolder;
}
base.OnInit(e);
}
}
public class ExtendedSingleLineTextField : Sitecore.Forms.Mvc.ViewModels.Fields.SingleLineTextField, IPlaceholderField
{
[VisualCategory("Custom Properties")]
[VisualProperty("Placeholder", 2)]
[DefaultValue("")]
public string PlaceHolder { get; set; }
}
2-从 / sitecore / system / Modules / Web Forms for Marketers / Settings / Field 类型/简单类型/单行文本复制单行文本到 / sitecore / system /模块/营销人员/设置/字段类型/自定义的Web表单 设置Assembly,Class和MVC Type
3 - 在\ Views \ Form \ EditorTemplates下创建一个新的chtml文件,名称为ExtendedSingleLineTextField.cshtml,它应与类名相同( ExtendedSingleLineTextField )
@using Sitecore.Forms.Mvc.Html
@using LendLease.Web.HtmlHelpers
@model LendLease.Extension.Sc.WFFM.ExtendedSingleLineTextField
@using (Html.BeginField())
{
@*@Html.TextBoxFor(m => m.Value, new { placeholder = Model.PlaceHolder })*@
@Html.ExtendedBootstrapEditor("value",Model.PlaceHolder,"",new []{""})
}
添加一个html助手,这样你就可以注入占位符我命名为BootstrapEditorHtmlHelperExtension.cs
public static class BootstrapEditorHtmlHelperExtension
{
public static MvcHtmlString ExtendedBootstrapEditor(this HtmlHelper helper, string expression, string placeholderText, string inlineStyle, string[] classes)
{
var str = string.Empty;
var viewModel = helper.ViewData.Model as IViewModel;
if (viewModel != null)
{
var styleSettings = viewModel as IStyleSettings;
if (styleSettings != null)
{
str = styleSettings.CssClass;
}
if (string.IsNullOrEmpty(placeholderText))
{
placeholderText = viewModel.Title;
}
}
return helper.Editor(expression, new
{
htmlAttributes = new
{
@class = (string.Join(" ", classes) + " form-control" + (string.IsNullOrEmpty(str) ? string.Empty : " " + str) + (helper.ViewData.Model is SingleLineTextField ? " dangerousSymbolsCheck" : string.Empty)),
placeholder = placeholderText,
style = (inlineStyle ?? string.Empty)
}
});
}
}

您可以通过使用附加属性扩展SingleLineText
来存储占位符的文本值来实现此目的。一旦属性到位,您将需要覆盖OnInit
方法并注入占位符属性(如果恰好设置了该属性)。
public interface IPlaceholderField
{
string PlaceholderText { get; set; }
}
以下是SingleLineText
[ValidationProperty("Text")]
public class SingleLineText : Sitecore.Form.Web.UI.Controls.SingleLineText, IPlaceholderField
{
[VisualCategory("Custom Properties")]
[VisualProperty("Placeholder Text", 2)]
[DefaultValue("")]
public string PlaceholderText { get; set; }
protected override void OnInit(EventArgs e)
{
// Set placeholder text, if present
if (!String.IsNullOrEmpty(PlaceholderText))
{
textbox.Attributes["placeholder"] = PlaceholderText;
}
base.OnInit(e);
}
}
最后,您需要在/sitecore/system/Modules/Web Forms for Marketers/Settings/Field Types/Custom/
下创建一个新的字段项定义,并将程序集设置为使用上面的类。如果在“表单设计器”中选择了字段,则新的占位符属性应显示在“自定义属性”类别下。

我使用以下代码创建自定义字段。它工作正常:))
internal class CustomType : SingleLineText
{
[VisualProperty("Placeholder", 100)]
[VisualCategory("Appearance")]
public string placeholderText
{
get;
set;
}
protected override void DoRender(System.Web.UI.HtmlTextWriter writer)
{
this.textbox.Attributes.Add("placeholder", this.PlaceholderText );
base.DoRender(writer);
}
}
然后我在 / sitecore / system / Modules / Web Forms for Marketers / Settings / Field Types / Custom 下创建了一个字段类型项目,并在项目中输入了程序集和类详细信息。
