实时监听组件中路由的变化，通过watch来进行监听，当路由发生变化时，重新赋值，重新执行从后台获取数据的操作

watch: {

'$route' (to, from) {

this.listQuery.keywords=this.$route.query.keywords

this.searchByKeywords()

}

},

methods: {

searchByKeywords() {

this.$store.dispatch('updateLoading', true)

fetchSearchByKeywords(this.listQuery)

.then(response => {

this.$store.dispatch('updateLoading', false)

this.listTotal = response.data.total

this.listData = response.data.data

})

.catch(error => {

console.log(error)

})

}

}
