我有这个函数在Coldfusion中生成slugs：
<cffunction name="generateSlug" output="false" returnType="string">
<cfargument name="str">
<cfargument name="spacer" default="-">
<cfset var ret = "" />
<cfset str = lCase(trim(str)) />
<cfset str = reReplace(str,"[àáâãäå]","a","all") />
<cfset str = reReplace(str,"[èéêë]","e","[ìíîï]","i","[òóôö]","o","[ùúûü]","u","[ñ]","n","[^a-z0-9-]","#spacer#","all") />
<cfset ret = reReplace(str,"#spacer#+","all") />
<cfif left(ret,1) eq "#spacer#">
<cfset ret = right(ret,len(ret)-1) />
</cfif>
<cfif right(ret,1) eq "#spacer#">
<cfset ret = left(ret,len(ret)-1) />
</cfif>
<cfreturn ret />
</cffunction>
然后我用它调用它：
<cfset stringToBeSlugged = "This is a string abcde àáâãäå èéêë ìíîï òóôö ùúûü ñ año ñññññññññññññ" /> <cfset slug = generateSlug(stringToBeSlugged) /> <cfoutput>#slug#</cfoutput>
但这是输出我这个slu ::
这-是-A-字符串ABCDE-A-A-A-A-A-A-E-E-E-E-I-I-I-I-O-O-O-O-U-U-U-U-N-A-NO-N-N-N-N-N-N-N-N-N-N-N-N-N
似乎所有重音字符都被正确替换了,但是这个函数在替换后插入了一个’ – ‘.为什么？
错误在哪里？
PD：我期待这个输出：
this-is-a-string-abcde-aaaaaa-eeee-iiii-oooo-uuuu-n-ano-nnnnnnnnnnnnn
谢谢.
解决方法
这对你有用吗？ (我已经改编了一个我们内部使用的类似脚本.)我相信我们在ColdFusion 8中使用它,因为我们仍然使用它与CF9.
<cffunction name="generateSlug" output="false" returnType="string">
<cfargument name="str" default="">
<cfargument name="spacer" default="-">
<cfset var ret = replace(arguments.str,"'","","all")>
<cfset ret = trim(ReReplaceNoCase(ret,"<[^>]*>","ALL"))>
<cfset ret = ReplaceList(ret,"À,Á,Â,Ã,Ä,Å,Æ,È,É,Ê,Ë,Ì,Í,Î,Ï,Ð,Ñ,Ò,Ó,Ô,Õ,Ö,Ø,Ù,Ú,Û,Ü,Ý,à,á,â,ã,ä,å,æ,è,é,ê,ë,ì,í,î,ï,ñ,ò,ó,ô,õ,ö,ø,ù,ú,û,ü,ý, ,&","A,A,AE,E,I,D,N,O,U,Y,a,ae,e,i,n,o,u,y,")>
<cfset ret = trim(rereplace(ret,"[[:punct:]]"," ","all"))>
<cfset ret = rereplace(ret,"[[:space:]]+","!","all")>
<cfset ret = ReReplace(ret,"[^a-zA-Z0-9!]","ALL")>
<cfset ret = trim(rereplace(ret,"!+",arguments.Spacer,"all"))>
<cfreturn ret>
</cffunction>
<cfset stringToBeSlugged = "This is a string abcde àáâãäå èéêë ìíîï òóôö ùúûü ñ año ñññññññññññññ" />
<cfoutput>"#stringToBeSlugged# = #generateSlug(stringToBeSlugged)#</cfoutput>
支持更多的国际性
如果你想扩大对国际字符的支持,你可以使用ICU4J(java)和Paul Hastings的Transliterator.CFC来音译所有字符,然后用破折号替换任何剩余的空格,破折号,斜线等.

安装两者后,您可以通过识别语言ID(要转换为)来转换非拉丁字符并传递要转换的字符串：
<cfset Transliterator = CreateObject("component","transliterator")>
<cfoutput>
<cfloop array="#TestStrings#" index="TestString">
<h3>TestString = "#TestString#"</h3>
<blockquote>
<div>CFC-1 = #Transliterator.transliterate('Latin-ASCII',TestString)#</div>
<div>CFC-2 = #Transliterator.transliterate('any-NFD; [:nonspacing mark:] any-remove; any-NFC',TestString)#</div>
</blockquote>
<hr>
</cfloop>
</cfoutput>
<h2>Available Language IDs</h2>
<cfdump var="#Transliterator.getAvailableIDs()#" label="Language IDs">
