スタンドアロン機能:
function toProperCase(s){
return s.replace(/([^\s:\-])([^\s:\-]*)/g,function($0,$1,$2){
return $1.toUpperCase()+$2.toLowerCase();
});
}
または String.prototype の拡張用:
String.prototype.toProperCase=function() {
return this.replace(/([^\s:\-])([^\s:\-]*)/g,function($0,$1,$2){
return $1.toUpperCase()+$2.toLowerCase();
});
}
"çoban ırmak becomes çOban ıRmak intead of Çoban Irmak Hello-wOrld".toProperCase();
// "Çoban Irmak Becomes Çoban Irmak Intead Of Çoban Irmak Hello-World"
アップデート:
次のコードは、ロケール固有の文字を変換するためのカスタム機能を使用します (部分的にテスト済み)。コードは、関数をString.prototype
: toLocaleProperCase2
、toLocaleLowerCase2
およびに追加しますtoLocaleUpperCase2
。
(function(){
// locale specific chars
// IMPORTANT: name of locale must be always in lower case (for "tr-TR" locale - "tr-tr") !!!
var localeInfos={
"tr-tr": { lower: { i:"İ", ı:"I", ş:"Ş", ğ:"Ğ", ü:"Ü", ç:"Ç", ö:"Ö" },
upper: { İ:"i", I:"ı", Ş:"ş", Ğ:"ğ", Ü:"ü", Ç:"ç", Ö:"ö" } }
},
localeInfo;
// helper vars
var mask="\\s:\\-", // add additional delimeters chars to the mask if needed
rg=new RegExp("([^"+mask+"])([^"+mask+"]*)","g");
var fnToLocaleLower=function(s){ return localeInfo.upper[s]; },
fnToLocaleUpper=function(s){ return localeInfo.lower[s]; },
fnToProper=function($0,$1,$2){
if(localeInfo){
if(localeInfo.lower.hasOwnProperty($1))$1=localeInfo.lower[$1];
$2=$2.replace(localeInfo.upperSearchRegExp,fnToLocaleLower);
}
return $1.toUpperCase()+$2.toLowerCase();
};
// helper calculations
var localeInfosKeys=Object.keys(localeInfos);
for(var i=0;localeInfo=localeInfos[localeInfosKeys[i]];i++){
localeInfo.lowerSearchRegExp=new RegExp("["+Object.keys(localeInfo.lower).join("")+"]","g");
localeInfo.upperSearchRegExp=new RegExp("["+Object.keys(localeInfo.upper).join("")+"]","g");
}
// extending String.prototype
String.prototype.toLocaleProperCase2=function toLocaleProperCase2(locale){
localeInfo=localeInfos[arguments.length?locale.toLowerCase():null];
return this.replace(rg,fnToProper);
};
String.prototype.toLocaleLowerCase2=function toLocaleLowerCase2(locale){
return ((localeInfo=localeInfos[arguments.length?locale.toLowerCase():null]) ?
this.replace(localeInfo.upperSearchRegExp,fnToLocaleLower):
