基于jquery实现拆分姓名的方法(纯JS版)

$.extend({
splitName: function(fullname){
var hyphenated = ['欧阳','太史','端木','上官','司马','东方','独孤','南宫','万俟','闻人','夏侯','诸葛','尉迟','公羊','赫连','澹台','皇甫',
'宗政','濮阳','公冶','太叔','申屠','公孙','慕容','仲孙','钟离','长孙','宇文','城池','司徒','鲜于','司空','汝嫣','闾丘','子车','亓官',
'司寇','巫马','公西','颛孙','壤驷','公良','漆雕','乐正','宰父','谷梁','拓跋','夹谷','轩辕','令狐','段干','百里','呼延','东郭','南门',
'羊舌','微生','公户','公玉','公仪','梁丘','公仲','公上','公门','公山','公坚','左丘','公伯','西门','公祖','第五','公乘','贯丘','公皙',
'南荣','东里','东宫','仲长','子书','子桑','即墨','达奚','褚师'];
var vLength = fullname.length;
var lastname = '', firstname = '';//前为姓,后为名
if(vLength > 2){
var preTwoWords = fullname.substr(0, 2);//取命名的前两个字,看是否在复姓库中
if($.inArray(preTwoWords, hyphenated) > -1){
lastname = preTwoWords;
firstname = fullname.substr(2);
}else{
lastname = fullname.substr(0, 1);
firstname = fullname.substr(1);
}
}else if(vLength == 2){//全名只有两个字时,以前一个为姓,后一下为名
lastname = fullname.substr(0, 1);
firstname = fullname.substr(1);
}else{
lastname = fullname;
}
return [lastname, firstname];
}
});
