基于jquery实现拆分姓名的方法（纯JS版）

之前已经分享过一个在dom中用户输入姓名后自动用js拆分成姓与名到表单中的jquery插件,由于项目的需要,需要一个在客户端自动拆分,但不需要将拆分结果呈现给用户的方法,所以又写了一个独立的方法,贴出来跟大家分享交流
复制代码代码如下:
$.extend（{
splitName: function（fullname）{
var hyphenated = ["欧阳","太史","端木","上官","司马","东方","独孤","南宫","万俟","闻人","夏侯","诸葛","尉迟","公羊","赫连","澹台","皇甫",
"宗政","濮阳","公冶","太叔","申屠","公孙","慕容","仲孙","钟离","长孙","宇文","城池","司徒","鲜于","司空","汝嫣","闾丘","子车","亓官",
"司寇","巫马","公西","颛孙","壤驷","公良","漆雕","乐正","宰父","谷梁","拓跋","夹谷","轩辕","令狐","段干","百里","呼延","东郭","南门",
"羊舌","微生","公户","公玉","公仪","梁丘","公仲","公上","公门","公山","公坚","左丘","公伯","西门","公祖","第五","公乘","贯丘","公皙",
"南荣","东里","东宫","仲长","子书","子桑","即墨","达奚","褚师"];
var vLength = fullname.length;
var lastname = "", firstname = "";//前为姓,后为名
if（vLength > 2）{
var preTwoWords = fullname.substr（0, 2）;//取命名的前两个字,看是否在复姓库中
if（$.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];
}
}）;
