js分割url字符串成为对象

function param2Obj(url) {
  const search = decodeURIComponent(url.split('?')[1]).replace(/\+/g, ' ')
  if (!search) {
    return {}
  }
  const obj = {}
  const searchArr = search.split('&')
  searchArr.forEach(v => {
    const index = v.indexOf('=')
    if (index !== -1) {
      const name = v.substring(0, index)
      const val = v.substring(index + 1, v.length)
      obj[name] = val
    }
  })
  return obj
}      

const search = decodeURIComponent(url.split('?')[1]).replace(/\+/g, ' ')
  if (!search) {
    return {}
  }
  const obj = {}
  const searchArr = search.split('&')
  searchArr.forEach(v => {
    const index = v.indexOf('=')
    if (index !== -1) {
      const name = v.substring(0, index)
      const val = v.substring(index + 1, v.length)
      obj[name] = val
    }
  })
  return obj
}
console.log(param2Obj('http://www.baidu.com?id=1&Items=2'))
//decodeURIComponent:为了解决中文在url上乱码问题
