Vuex.如何使用 v-for 从商店渲染数据 [英] Vuex. How to render data from store using v-for
问题描述
我有几个组件的应用程序.我使用 Vuex 来存储数据,所以我可以在不同的组件中使用它.现在我需要使用 v-for 渲染一些 div.我这样做:
VueX/Modules/shows.js
const state = {显示: [{name: '幸运',场地:场地",时间:'下午 6:00'},{name: '幸运',场地:场地",时间:'下午 6:00'}]}导出默认{状态}
我需要使用数据的组件:
<模板><div class="dashboard__details 仪表板__details--shows"v-for="在节目中展示"><h3 class="dashboard__name">{{show.name}} @ {{show.venue}}<span class="dashboard__time">{{show.time}}</span><div class="dashboard__btnBlock"><按钮">详细信息</按钮>
</模板><脚本>从 'vuex' 导入 { mapState }从'./ReportIssue'导入报告问题从 './InviteFriend' 导入 InviteFriend导出默认{name: '仪表板',组件:{ ReportIssue, InviteFriend },计算:地图状态({显示:状态 =>{返回 state.shows}})}
如果我在组件的数据中有数据,它就可以工作,但如果我将数据存储在 Vuex 中,它就无法工作.
如果你正在使用一个模块,那么你需要在你的商店中配置它:
# 你的 Vuex 商店从./VueX/Modules/shows.js"导入节目导出默认新 Vuex.Store({模块:{显示,},...
然后当您在组件中引用它时,您将调用模块而不是根状态:
出口默认{name: '仪表板',组件:{ ReportIssue, InviteFriend },计算:地图状态({显示:({ 显示}) =>节目.shows})}
您可能想重命名模块以避免 shows.shows
但您应该明白
I have app with couple components. I use Vuex to store data so I could use it in different components. Now I need to render some divs using v-for. I do as follows:
VueX/Modules/shows.js
const state = {
shows: [
{
name: 'Hard Luck',
venue: 'The Venue',
time: '6:00 pm'
},
{
name: 'Hard Luck',
venue: 'The Venue',
time: '6:00 pm'
}
]
}
export default {
state
}
Component where I need to use data:
<template>
<div class="dashboard__details dashboard__details--shows"
v-for="show in shows">
<h3 class="dashboard__name">
{{show.name}} @ {{show.venue}}
</h3>
<span class="dashboard__time">{{show.time}}</span>
<div class="dashboard__btnBlock">
<button">Details</button>
</div>
</div>
</template>
<script>
import { mapState } from 'vuex'
import ReportIssue from './ReportIssue'
import InviteFriend from './InviteFriend'
export default {
name: 'dashboard',
components: { ReportIssue, InviteFriend },
computed: mapState({
shows: state => {
return state.shows
}
})
}
</script>
It works if I have data in the component's data but I can't make it work if I store data in Vuex.
if you are using a module then you need to of configured that within your store:
# your Vuex store
import shows from './VueX/Modules/shows.js'
export default new Vuex.Store({
modules: {
shows,
},
...
Then when you reference it within a component you call the module not the root state:
export default {
name: 'dashboard',
components: { ReportIssue, InviteFriend },
computed: mapState({
shows: ({ shows }) => shows.shows
})
}
You probably want to rename the module so to avoid shows.shows
but you should get the idea
