ASP.NET Forums 2.0 本地化修改(四)
今天主要讲几个小问题，给编辑器增加新的按钮，这里用的比较简单的方法，大家可以参考增加自己需要的工具栏：
增加FTB工具栏按钮主要是继承FreeTextBoxControls.ToolbarButton;
这次要增加5个按钮，分别为增加WMP音频，WMP视频，REALONE音频，REALONE视频以及FLASH按钮；
1、首先增加资源文件，打开languages/zh-CN/Resources.xml,增加如下资源：
<resource name = "CreateEditPost_FTB_FlashButton">插入Flash文件(.swf)</resource>
<resource name = "CreateEditPost_FTB_RPAButton">插入RealPlayer音频文件</resource>
<resource name = "CreateEditPost_FTB_RPVButton">插入RealPlayer视频文件</resource>
<resource name = "CreateEditPost_FTB_WMAButton">插入Windows Media Player音频文件</resource>
<resource name = "CreateEditPost_FTB_WMVButton">插入Windows Media Player视频文件</resource>
<resource name = "CreateEditPost_FTB_RPAButton">插入RealPlayer音频文件</resource>
<resource name = "CreateEditPost_FTB_RPVButton">插入RealPlayer视频文件</resource>
<resource name = "CreateEditPost_FTB_WMAButton">插入Windows Media Player音频文件</resource>
<resource name = "CreateEditPost_FTB_WMVButton">插入Windows Media Player视频文件</resource>
2、准备解析对应内容的正则表达式，看下面代码，直接有注释（将该代码插入到Components/Components/Transforms.cs的BBcodeToHtml方法的最下面）
/*
表达式：[rpa play=true]rpaUrl[/rpa] 说明： 支持realplayer的音频， 参数： play参数为true或false,是否自动开始播放 rpaUrl为音频文件地址 
*/
encodedString = Regex.Replace(encodedString, @"\[rpa[ ]play=((true|false))\](\S*)\[/rpa\]", "<OBJECT classid=CLSID:CFCDAA03-8BE4-11CF-B84B-0020AFBBCCFA height=32 id=video2 width=500>" + "<PARAM NAME=SRC VALUE=\"$3\">" + "<PARAM NAME=AUTOSTART VALUE=$2>" + "<PARAM NAME=CONTROLS VALUE=controlpanel>" + "<PARAM NAME=CONSOLE VALUE=Clip1></OBJECT>" + "<BR><a href=\"$3\" target=_blank>$3</a>", RegexOptions.IgnoreCase); /* 表达式：[rpv play=true,width=100,height=200]rpvUrl[/rpv] 说明： 支持realplayer的视频， 参数： play参数为true或false,是否自动开始播放 width:视频文件宽度 height:食品文件高度 rpvUrl为视频文件地址 */ encodedString = Regex.Replace(encodedString, @"\[rpv[ ]play=((true|false)),width=(\d*),height=(\d*)\](\S*)\[/rpv\]", "<OBJECT classid=clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA class=OBJECT id=RAOCX width=$3 height=$4>" + "<PARAM NAME=SRC VALUE=\"$5\">" + "<PARAM NAME=AUTOSTART VALUE=$2>" + "<PARAM NAME=CONSOLE VALUE=Clip1>" + "<PARAM NAME=CONTROLS VALUE=imagewindow>" + "</OBJECT><br>" + "<OBJECT classid=CLSID:CFCDAA03-8BE4-11CF-B84B-0020AFBBCCFA height=32 id=video2 width=$3>" + "<PARAM NAME=SRC VALUE=\"$5\">" + "<PARAM NAME=AUTOSTART VALUE=$2>" + "<PARAM NAME=CONTROLS VALUE=controlpanel>" + "<PARAM NAME=CONSOLE VALUE=Clip1></OBJECT>" + "<BR><a href=\"$5\" target=_blank>$5</a>", RegexOptions.IgnoreCase); /* 表达式：[wma play=true]wmaUrl[/wma] 说明： 支持windows media player的音频， 参数： play参数为true或false,是否自动开始播放 wmaUrl为音频文件地址 */ encodedString = Regex.Replace(encodedString, @"\[wma[ ]play=((true|false))\](\S*)\[/wma\]", "<object align=middle classid=CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6 class=OBJECT id=MediaPlayer width=500 height=63>" + "<param name=ShowStatusBar value=true>" + "<param name=autoStart value=$2>" + "<param name=url value=\"$3\">" + "<embed type=application/x-oleobject codebase=http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701 flename=mp src=\"$3\" width=500 height=50></embed></object>" + "<BR><a href=\"$3\" target=_blank>$3</a>", RegexOptions.IgnoreCase); /* 表达式：[wmv play=true,width=100,height=200]wmvUrl[/wmv] 说明： 支持windows media player的视频 参数： play参数为true或false,是否自动开始播放 width:视频文件宽度 height:食品文件高度 wmvUrl为视频文件地址 */ encodedString = Regex.Replace(encodedString, @"\[wmv[ ]play=((true|false)),width=(\d*),height=(\d*)\](\S*)\[/wmv\]", "<object align=middle classid=CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6 class=OBJECT id=MediaPlayer width=$3 height=$4>" + "<param name=autoStart value=$2>" + "<param name=ShowStatusBar value=true>" + "<param name=url value=$5>" + "<PARAM name=uiMode value=full>" + "<PARAM name=stretchToFit value=true>" + "<embed type=application/x-oleobject codebase=http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701 flename=mp src=\"$5\" width=$3 height=$4></embed>" + "</object>" + "<BR><a href=\"$5\" target=_blank>$5</a>", RegexOptions.IgnoreCase); /* 表达式：[flash width=500,height=400]url[/flash] 说明： 支持flash 参数： width为flash宽度 height为flash高度 url为flash的地址 */ encodedString = Regex.Replace(encodedString, @"\[flash[ ]width=(\d*),height=(\d*)\](\S*)\[/flash\]", "<OBJECT codeBase=\"http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0\" " + " classid=\"clsid:d27CDB6E-AE6D-11cf-96B8-444553540000\" " + "width=$1 height=$2>" + "<PARAM NAME=movie VALUE=\"$3\">" + "<PARAM NAME=quality VALUE=high>" + "<embed src=\"$3\" width=$1 height=$2 quality=high name=index type=\"application/x-shockwave-flash\" pluginspage=\"http://www.macromedia.com/go/getflashplayer\"/>" + "</OBJECT>" + "<BR><a href=\"$3\" target=_blank>$3</a>", RegexOptions.IgnoreCase);
3、为了防止程序将UBB代码作为表情符替换，修改FormatPost方法，具体看代码说明即可，主要是调换一下顺序：
public static string FormatPost(string rawPostBody, PostType postType, bool allowCustomTransforms) {
string formattedPost = rawPostBody; // Perform HTML Encoding of any tag elements, if not PostType.HTML // if (postType != PostType.HTML)
{
formattedPost = HttpUtility.HtmlEncode(formattedPost); if (postType != PostType.Poll) formattedPost = formattedPost.Replace("\n", Globals.HtmlNewLine);
} // Remove any script code // formattedPost = Transforms.StripScriptTags(formattedPost); // Fix to reverse certain items that were HtmlEncoded above // formattedPost = UnHtmlEncode(formattedPost); // Peform specialized transforms first. // if (allowCustomTransforms) { formattedPost = EmoticonTransforms(formattedPost); formattedPost = PerformSpecializedTransforms(formattedPost); } //edited by jacky //2004-10-2 //将其从allowCustomTransforms上移动到下，防止转换ubb生成后的代码 // Do BBCode transform, if any // formattedPost = BBcodeToHtml(formattedPost); if (postType == PostType.Poll) { ArrayList voteOptions = BodyToVoteOptions(formattedPost); formattedPost = CreateVoteXml(voteOptions).OuterXml; } return formattedPost; }
4、基础工作已经做完，下面增加FTB按钮：
1）FlashButton， 在Controls/FreeTextBox下增加一文件FlashButton.cs，代码如下：
using System;using AspNetForums.Components;using FreeTextBoxControls;namespace AspNetForums.Controls{ /// <summary> /// FlashButton 的摘要说明。 /// </summary> public class FlashButton : ToolbarButton { public FlashButton():base(ResourceManager.GetString("CreateEditPost_FTB_FlashButton"),"FTB_FlashUBB","button_flash") { ScriptBlock = @"function FTB_FlashUBB(ftbName) { FTB_SurroundText(ftbName,'[flash width=500,height=400]Flash文件地址[/flash]','');}"; } }}2）RPAButton，插入RealPlayer音频文件，在Controls/FreeTextBox下增加一文件RPAButton.cs，代码如下：
using System;using AspNetForums.Components;using FreeTextBoxControls;namespace AspNetForums.Controls{ /// <summary> /// RPAButton 的摘要说明。 /// </summary> public class RPAButton : ToolbarButton { public RPAButton():base(ResourceManager.GetString("CreateEditPost_FTB_RPAButton"),"FTB_RPA","button_rpa") { ScriptBlock = @"function FTB_RPA(ftbName) { FTB_SurroundText(ftbName,'[rpa play=true]RealPlayerAudio文件地址[/rpa]','');}"; } }}3）RPVButton，在同上文件夹中，增加RPVButton.cs文件，代码如下：
using AspNetForums.Components;using FreeTextBoxControls;namespace AspNetForums.Controls{ /// <summary> /// RPVButton 的摘要说明。 /// </summary> public class RPVButton : ToolbarButton { public RPVButton() : base(ResourceManager.GetString("CreateEditPost_FTB_RPVButton"), "FTB_RPV", "button_rpv") { ScriptBlock = @"function FTB_RPV(ftbName) { FTB_SurroundText(ftbName,'[rpv play=true,width=500,height=350]RealPlayerVedio文件地址[/rpv]','');}"; } }}4）WMAButton，用于插入Windows Media 音频文件，增加WMAButton.cs文件，代码如下：
using AspNetForums.Components;using FreeTextBoxControls;namespace AspNetForums.Controls{ /// <summary> /// WMAButton 的摘要说明。 /// </summary> public class WMAButton : ToolbarButton { public WMAButton() : base(ResourceManager.GetString("CreateEditPost_FTB_WMAButton"), "FTB_WMA", "button_wma") { ScriptBlock = @"function FTB_WMA(ftbName) { FTB_SurroundText(ftbName,'[wma play=true]WindowsMediaAudio文件地址[/wma]','');}"; } }}5）WMVButton，在同上目录下增加WMVButton.cs,代码如下：
using System;using AspNetForums.Components;using FreeTextBoxControls;namespace AspNetForums.Controls{ /// <summary> /// WMVButton 的摘要说明。 /// </summary> public class WMVButton : ToolbarButton { public WMVButton() : base(ResourceManager.GetString("CreateEditPost_FTB_WMVButton"), "FTB_WMV", "button_wmv") { ScriptBlock = @"function FTB_WMV(ftbName) { FTB_SurroundText(ftbName,'[wmv play=true,width=500,height=350]WindowsMediaVideo文件地址[/wmv]','');}"; } }}
5、最后一步，将这些按钮添加到页面上，打开themes/default/skins/View-CreateEditPost.ascx,找到FTB的代码，在<Toolbars>标签中，插入以下代码：
<FTB:Toolbar> <Forums:FlashButton runat="server"/> <Forums:RPAButton runat="server"/> <Forums:RPVButton runat="server"/> <Forums:WMAButton runat="server"/> <Forums:WMVButton runat="server"/> </FTB:Toolbar>
OK，一切都已经完成，当然这里采用的是插入的比较简单的方法，也可以修改为采用向导方式由用户输入文件地址、视频文件大小、是否自动播放等。
