vue如何动态修改$router参数

// 创建一个包含当前 URL 参数的对象
export const getURLParameters = (url) =>
  (url.match(/([^?=&]+)(=([^&]*))/g) || []).reduce(
    (a, v) => (
      (a[v.slice(0, v.indexOf('='))] = v.slice(v.indexOf('=') + 1)), a
    ),
    {}
  );
 
/**
 * 替换地址栏参数
 * @param {key,value}
 */
export const replaceRouteQuery = (query, params) => {
  let href = window.location.href;
  let origin = href.split('?')[0];
 
  const routeObj = Object.assign({}, getURLParameters(href));
 
  for (let key in params) {
    routeObj[key] = params[key];
  }
 
  let isFirst = true, str = '';
  for (let key in routeObj) {
    str += `${isFirst ? '?' : '&'}${key}=${routeObj[key]}`;
    isFirst = false;
  }
 
  href = origin + str;
  if (window.history) {
    // 支持History API
    window.history.replaceState(null, '', href);
  }
 
  Object.assign(query, params);
}; 
 
// 调用: 
replaceRouteQuery($route.query, { 'startDate': '2020-01-01' })

import merge from 'webpack-merge';
 
//修改原有参数        
this.$router.push({
    query:merge(this.$route.query,{'XXXXXXXX':'630'})
})
 
//新增一个参数：
this.$router.push({
    query:merge(this.$route.query,{'XXXXXXXX':'我是新增的一个参数，哈哈哈哈'})
})
 
//替换所有参数：
 this.$router.push({
    query:merge({},{'XXXXXXXX':'630'
})
