我将vuex升级到2.0,并想知道在数据初始化之前它是否可能使用mapstate / getter?
在Vuex 1.0中,vuex状态将在data()之前映射,因此我可以调用this
然后调用我想要访问的状态
import { mapGetters } from 'vuex'
export default {
vuex: {
getters: {
userSettings: ({ settings }) => settings.userSettings,
}
},
data: function () {
return {
sendEmails: this.userSettings.sendEmails
}
}
}
但是在Vuex 2.0中,我必须做this.$store.state.settings.UserSettings.sendEmails
import { mapGetters, mapState } from 'vuex'
export default {
data: function () {
return {
sendEmails: this.$store.state.settings.UserSettings.sendEmails
}
}
computed: {
...mapGetters({
settings: "settings"
})
}
有没有办法在data()之前初始化该状态?我有多个组件在数据初始化中使用状态并且必须调用this.$store.state
?我意识到我可以做一些解构,但我只是想知道我是否可以避免这种情况。

我会在sendEmails
mounted
import { mapGetters, mapState } from 'vuex'
export default {
data: function () {
return {
sendEmails: []
}
}
computed: {
...mapGetters({
settings: "settings"
})
},
mounted: function() {
if (this.settings.UserSettings){
this.sendEmails = this.settings.UserSettings.sendEmails
}
}
}
