telerik - RadEditor - 如何指定允许的标签列表

Question

有没有办法指定 RadEditor 中允许的 HTML 标签列表？例如，如果我只希望编辑器中允许以下标签：

b, u, i, strong, br, p

易于配置的东西，例如 ToolsFile.xml 文件中的属性。

我在任何地方都找不到这些信息。

您可以在此 Telerik 论坛主题中使用提供的自定义内容过滤器：

干得好：

<script type="text/javascript">
function OnClientLoad(editor, args) {
   editor.get_filtersManager().add(new AllowedTagsFilter());
}
AllowedTagsFilter = function() {
AllowedTagsFilter.initializeBase(this);
this.set_isDom(false);
this.set_enabled(true);
this.set_name("AllowedTagsFilter");
this.set_description("Strip the unwanted tags from RadEditor");
}
 AllowedTagsFilter.prototype =
 {
   getHtmlContent: function(content) {
   return this._removeHtmlTags(content);
 },
getDesignContent: function(content) {
   return this._removeHtmlTags(content);
},
 _removeHtmlTags: function(initContent) {
   var cleanContent;
   //Perform necessary REGEX replacement to remove unsupported HTML tags
   //Supported Reporting HTML tags: FONT, STRONG, B, EM, I, U, A, OL, UL, LI, DIV, SPAN, P, BR, CENTER
   //HTML must be XHTML valid, too, but Editor already provides that filter
   //Following REGEX will remove all HTML tags EXCEPT those expliclitly listed
   cleanContent = initContent.replace(new RegExp("<(?!\/?(font|strong|b|em|(i(?!mg))|u|a|ol|ul|li|div|span|p|br|center)(?=>|\s?.*>))\/?.*?>", "ig"), "");
   return cleanContent;
 }
}
AllowedTagsFilter.registerClass('AllowedTagsFilter', Telerik.Web.UI.Editor.Filter);
</script>
<telerik:RadEditor runat="server" OnClientLoad="OnClientLoad" ID="RadEditor1">
<Content>sample content test <br/> test</Content>
</telerik:RadEditor>

你不能那样做。你可以做的是：

• disable all tools that can generate complex HTML. Leave only bold, italic, underline. Start off from this article: http://www.telerik.com/help/aspnet-ajax/editor-toolbar-intro.html that treats the basics of modifying the RadEditor toolbars.
• Disable the HTML mode so uses cannot enter HTML content by themselves: http://www.telerik.com/help/aspnet-ajax/editor-edit-modes.html.
