自定义扩展实现相对于addRoutes的removeRoutes方法——vue-router

使用vue-router的addRoutes方法做登录权限控制，当用户推出登录回到login页后，切换不同权限的账号，如果不reload页面，会导致router权限问题，故在vue-router代码中加入自定义的removeRoutes方法，代码如下(不保证无bug哦！)

1、
/**
 * @name removeRouteMap
 * @param {*} routes
 * @param {*} pathList
 * @param {*} pathMap
 * @param {*} nameMap
 * @description 删除
 * @author cjs1992
 * @date 2018-11-28 16:35
 */
function removeRouteMap (routes, pathList, pathMap, nameMap, ifDeep) {
  if (!ifDeep) {
    for (var i = pathList.length - 1; i >= 0;i--) {
      if (routes.path === pathList[i].path) {
        pathList.splice(i, 1);
        delete pathMap[routes.path]
        break;
      }
    }
    return;
  }
  if (routes.children && reoute.children.length !== 0) {
    for (var i = 0;i < routes.children.length;i++) {
      removeRouteMap(routes.children[i], pathList, pathMap, nameMap, ifDeep);
    }
    removeRouteMap(routes, pathList, pathMap, nameMap, false)
  } else {

    for (var i = pathList.length - 1; i >= 0;i--) {
      // console.log(pathList.length, 'pathList.length');console.log(routes, pathList)
      if (routes.path === pathList[i]) {
        pathList.splice(i, 1);
        delete pathMap[routes.path]
        break;
      }
    }
  }
}

2、
/**
   * @name removeRoutes
   * @description 定义
   * @author cjs1992
   * @date 2018-11-28 16:34
   */
  function removeRoutes (routes) {
    // console.log(removeRouteMap, routes, pathList, pathMap, nameMap);
    for (var i = 0;i < routes.length;i++) {
      removeRouteMap(routes[i], pathList, pathMap, nameMap, true)
    }
  }

3、
/**
 * @name removeRoutes
 * @description 定义清除路由的方法
 * @author cjs1992
 * @date 2018-11-28 16:30
 */
VueRouter.prototype.removeRoutes = function removeRoutes (routes) {
  this.matcher.removeRoutes(routes);
};
