基于iview的router常用控制方式

//变更当前路由(有历史记录,建议使用此方式)
this.$router.push({
  name:'routerName',
  params:routerParam
})
//变更当前路由(无历史记录)
this.$router.replace({
  name:'routerName',
  routerParam
})

/**
 * @description 根据name/params/query判断两个路由对象是否相等
 * @param {*} route1 路由对象
 * @param {*} route2 路由对象
 */
export const routeEqual = (route1, route2) => {
 return route1.name === route2.name
 // 此处改变相同路由的判断方式,改为name相同即认为相同
 // const params1 = route1.params || {}
 // const params2 = route2.params || {}
 // const query1 = route1.query || {}
 // const query2 = route2.query || {}
 // return (route1.name === route2.name) && objEqual(params1, params2) && objEqual(query1, query2)
}
