url自动获取相关参数值

url,得到其中相关的参数

export function getCode(){
  var search = window.location.hash
  getURLParameter(search, 'code')
}

// 获取url中对应的参数
function getURLParameter(url, paramName) {
  var urlParams = url.split("?")[1]//或者url.search获取参数字符串
  var paramArray = urlParams.split("&")
  var len = paramArray.length
  var paramObj = {}//json对象
  var arr = []//数组对象
  for (var i = 0; i < len; i++) {
      arr = paramArray[i].split("=")
      paramObj[arr[0]] = arr[1]
  }
  for (key in paramObj) {
      if (key == paramName) {
          return paramObj[paramName]
          break
      }
  }
}
