URL 参数转对象

export function parseQueryString(url) {
    url = url ? url:window.location.search ;
    let search = url[0] === '?' ? url : url.substring(url.lastIndexOf('?')); 
    let q = {};
    search.replace(/([^?&=]+)=([^&]+)/g, (_, k, v) => q[k] = decodeURIComponent(v));
    return q;
}

获取URL参数

export function getQueryString(name) {
  const reg = new RegExp('(^|&)' + name + '=([^&]*)(&|$)', 'i')
  const r = window.location.search.substr(1).match(reg)
  if (r !== null) {
    return decodeURI(r[2])
  }
  return null
}

获取URL hash后面的参数

export getHashQueryString = (key) => {
  const after = window.location.href.split('?')[1]
  if (after) {
    const reg = new RegExp(`(^|&)${  key  }=([^&]*)(&|$)`)
    const r = after.match(reg)
    if (r != null) {
      return decodeURIComponent(r[2])
    }
    return null
  }
  return null
}

对象序列化

export function serialize(query, encode = false) {
  return Object.keys(query)
    .map((key) => `${key}=${encode ? encodeURIComponent(query[key]) : query[key]}`)
    .join('&')
}
