正则匹配

写一个函数，使用正则获取当前浏览器的多参数

如    http://www.sodacar.com/vehicles?car=13242&station=83212jde  
返回  {car: "13242", station: "83212jde"}

实现：

// 方案一
    const parseQueryString = (url) => {
        const reg_url = /^[^\?]+\?([\w\W]+)$/
        const reg_para = /([^&=]+)=([\w\W]*?)(&|$|#)/g
        const arr_url = reg_url.exec(url)
        let ret = {}
        if (arr_url && arr_url[1]) {
            let str_para = arr_url[1]
            let = result
            while ((result = reg_para.exec(str_para)) != null) {
                // debugger
                ret[result[1]] = result[2]
            }
        }
        return ret
    }
// 方案二
    const getParams = (url) => {
        let obj = {}
        const par = /^[^\?]+\?([\w\W]+)$/.exec(url)[1]
        par.replace(/([^&=]+)=([\w\W]*?)(&|$|#)/g, (match, $1, $2) => {
             obj[$1] = $2
        })
        return obj 
    }
