在我的Vue應用程序中,我有一個編輯記錄的視圖。從該組件中,我(1)調用vuex操作將記錄保存到數據庫,(2)調用$router.push()
導航回總覽視圖。 vuex操作將使用AJAX持續記錄,然後將返回的記錄推送(替換或追加)到商店中的概覽列表。問題在於,除非我進行一些手動導航,否則這些更改不會顯示在總覽視圖中。Vue.js/vuex UI在編程導航上沒有更新
vuex/store.js:
import Vue from 'vue'
import Vuex from 'vuex'
import $ from 'jquery'
Vue.use(Vuex)
export default new Vuex.Store({
state: {
records: [],
activeRecord: {}
},
mutations: {
pushRecord: function(state, record) {
var added = false;
for (var i = 0; i < state.records.length; i++) {
if (state.records[i]._id == record._id) {
state.records[i] = record;
added = true;
break;
}
}
if (!added) {
state.records.push(record);
}
}
},
actions: {
saveRecord({ commit, state }) {
$.ajax({
type: "POST",
url: "http://127.0.0.1:8080/record",
data: JSON.stringify(state.activeRecord),
dataType: "json",
contentType: "application/json"
}).done(function(data) {
commit("pushRecord", data)
});
}
}
})
RecordDetail.vue(注意後續的調度和導航):
export default {
name: "record-detail",
computed: {
record() {
return this.$store.state.activeRecord
}
},
methods: {
save: function() {
this.$store.dispatch("saveRecord")
this.$router.push({ path: '/records' })
}
}
}
