编写一个简单的命令行参数解析函数

function parsestr(str)

{
var bigarr=str.split("-");
var res=[];
for(var i=1;i<bigarr.length;i++)
{
var smallarr=[];
var obj={}
smallarr=bigarr[i].split(" ");
obj.key=smallarr[0];
obj.value=smallarr[1];
res.push(obj);
}
return res;
}
var as='-name Lily -age 21 -school "University of Oxford"';
console.log(parsestr(as));

 * @param s 传入的命令行
 * @return 解析之后的命令行参数
 * @throws Exception 格式异常
 * @brief 命令行参数解析
