js获取url参数，非window环境

export const getUrlQuery = (url) => {
  if(!url) return;
    let newUrl = url
    let arr = []
    if (url.indexOf('?') > -1) {
      newUrl = url.split('?')[1]
    }
    arr = newUrl.split('&')
    const obj = {}
    arr.forEach(e => {
      let sp = e.split('=')
      obj[sp[0]] = sp[1]
    })
  return obj;
}
