写一个命令行字符的解析函数。

例：parse('-name lily -age 25 -school "chengdu university"');
返回的是[-name lily,-age 25, -school "chengdu university"]

正则

 /(?:-([A-Za-z]+)\s+([A-Za-z0-9]+|\".*?\")\s*)/g

function parse(str) {
    var ans = {};
    var parsePatt = /(?:-([A-Za-z]+)\s+([A-Za-z0-9]+|\".*?\")\s*)/g;
    var result;
    do {
        result = parsePatt.exec(str);
        if(result) {
            ans[result[1]] = result[2];
        }
        
    } while (result != null)
    return ans;
}

parse('-name lily  -age 25  -school "chengdu university"');
