如何将camelCase转换为带空格的字符串？ （如驼峰为“驼峰”）
使用ColdFusion，我想驼峰字符串转换成一个人类可读的字符串，如：如何将camelCase转换为带空格的字符串？ （如驼峰为“驼峰”）
的firstName - >名字
而且，这将最好做全部内联，像Ucase(rereplace('myCamelCaseString',[regex]," "))。如果内联不可行，那么可能是UDF？
#rereplace("camelCaseString","([A-Z])"," \1","all")#
编辑：下面的版本将处理小写的第一个字符。
#rereplace(rereplace("camelCaseString","(^[a-z])","\u\1"),"([A-Z])"," \1","all")#
我不认为你可以用一个正则表达式一次完成它，因为它们不支持递归/迭代，所以你不能使它在任何数量的wordsPushedTogether的字符串上工作。
你可以做一个循环，以空白字符串开头，循环遍历camelCase字符串，并且每次找到大写字母时，先拆分它之前的字母并用空格将它附加到新字符串中。
我使用过的RegEx的每种口味都有一个全球标志。 CF让您可以选择只搜索一个字符串中的一个匹配项或全部匹配项。 – 2012-02-24 16:33:07
CFLib是你的朋友！
有camelToSpace()这是做你在问什么，除了大写。
<cfscript>
/**

function camelToSpace(str) {
var rtnStr=lcase(reReplace(arguments.str,"([A-Z])([a-z])"," \1\2","ALL"));
if (arrayLen(arguments) GT 1 AND arguments[2] EQ true) {
rtnStr=reReplace(arguments.str,"([a-z])([A-Z])","\1 \2","ALL");
rtnStr=uCase(left(rtnStr,1)) & right(rtnStr,len(rtnStr)-1);
}
return trim(rtnStr);
}
</cfscript>
如果你想利用得到的字符串中的每个单词，有CapFirstTitle()
<cfscript>
/**
* Returns a string with words capitalized for a title.
* Modified by Ray Camden to include var statements.
* Modified by James Moberg to use structs, added more words, and reset-to-all-caps list.
*
* @param initText String to be modified. (Required)
* @return Returns a string.

*/
function capFirstTitle(initText){
var j = 1; var m = 1;
var doCap = true;
var tempVar = "";
/* Make each word in text an array variable */
var Words = ListToArray(LCase(trim(initText)), " ");
var excludeWords = structNew();
var ResetToALLCAPS = structNew();
/* Words to never capitalize */
tempVar = ListToArray("a,above,after,ain't,among,an,and,as,at,below,but,by,can't,don't,for,from,from,if,in,into,it's,nor,of,off,on,on,onto,or,over,since,the,to,under,until,up,with,won't");
for(j=1; j LTE (ArrayLen(tempVar)); j = j+1){
excludeWords[tempVar[j]] = 0;
}
/* Words to always capitalize */
tempVar = ListToArray("II,III,IV,V,VI,VII,VIII,IX,X,XI,XII,XIII,XIV,XV,XVI,XVII,XVIII,XIX,XX,XXI");
for(j=1; j LTE (ArrayLen(tempVar)); j = j+1){
ResetToALLCAPS[tempVar[j]] = 0;
}
/* Check words against exclude list */
for(j=1; j LTE (ArrayLen(Words)); j = j+1){
doCap = true;
/* Word must be less than four characters to be in the list of excluded words */
if(LEN(Words[j]) LT 4){
if(structKeyExists(excludeWords,Words[j])){ doCap = false; }
}
/* Capitalize hyphenated words */
if(ListLen(trim(Words[j]),"-") GT 1){
for(m=2; m LTE ListLen(Words[j], "-"); m=m+1){
tempVar = ListGetAt(Words[j], m, "-");
tempVar = UCase(Mid(tempVar,1, 1)) & Mid(tempVar,2, LEN(tempVar)-1);
Words[j] = ListSetAt(Words[j], m, tempVar, "-");
}
}
/* Automatically capitalize first and last words */
if(j eq 1 or j eq ArrayLen(Words)){ doCap = true; }
/* Capitalize qualifying words */
if(doCap){ Words[j] = UCase(Mid(Words[j],1, 1)) & Mid(Words[j],2, LEN(Words[j])-1); }
if (structKeyExists(ResetToALLCAPS, Words[j])) Words[j] = ucase(Words[j]);
}
return ArrayToList(Words, " ");
}
</cfscript>
所以，一旦你有了到位的UDF的，你可以做
CapFirstTitle(camelToSpace('myCamelCaseString'))
这将返回My Camel Case String。
下面是共同一串字转换成骆驼两种功能。单词可以用空格或下划线分隔，但您可以根据需要添加其他字符。
<cffunction name="camelCase" access="public" output="false" returntype="string">
<cfargument name="sourceString" type="string" required="true">
<cfscript>
var s = LCase(Trim(arguments.sourceString));
s = camelCaseByWordSeperator(s, " ");
s = camelCaseByWordSeperator(s, "_");
return s;
</cfscript>
</cffunction>
<cffunction name="camelCaseByWordSeperator" access="private" output="false" returntype="string">
<cfargument name="sourceString" type="string" required="true">
<cfargument name="separator" type="string" required="false" default="_">
<cfscript>
var s = arguments.sourceString;
var wordBreakPos = Find(arguments.separator, s);
while (wordBreakPos gt 0) {
lens = Len(s);
if (wordBreakPos lt lens) {
s = Replace(Left(s, wordBreakPos), arguments.separator, "", "all") & UCase(Mid(s, wordBreakPos+1, 1)) & Right(s, lens - wordBreakPos - 1);
} else {
s = Replace(s, arguments.separator, "", "all");
}
wordBreakPos = Find(arguments.separator, s);
}
return s;
</cfscript>
</cffunction>
顺便提及，我能够将代码从@ AL-埃弗里特和@ phontom42结合与此落得：'#uCase（左（rereplace（element.name， “（[AZ]）”，”所有“），1））和右（rereplace（element.name，”（[AZ]）“，”\ 1“，”all“），len（rereplace（element.name，”（[ AZ]）“，”\ 1“，”all“）） - 1）＃' 虽然不是很优雅。可能会与UDF解决方案一起使用。 – eterps 2012-02-24 16:58:23
