vuexlink里面的同一个组件如何显示多次
How to display many times the same component with vuex link inside
我是 Vue 和 Vuex 的新手。
我制作了一个带有单选按钮的组件,该组件与商店双向绑定。
现在该组件正在运行,我想通过多次调用它来将它用于多个项目,并向它指示它应该绑定到 vuex 存储的哪个项目。这样,我将能够循环包含应用单选按钮修改的所有项目的数组。
在我的店里,我有这个数组:
state {
[...other data...]
arrayX {
item1: { name : 'a', value : 'nok'}
item2: { name : 'b', value : 'ok}},
[...other data...]
此数组与组件内的 v-model 绑定:
<template>
<div class="radio">
<input type="radio" name="a" value="nok" v-model="arrayX.item1.value" id="nok"/>
<label for="nok"> Nok </label>
</div>
<div class="radio">
<input type="radio" name="a" value="" v-model="arrayX.item1.value" id="empty"/>
<label for="empty">None</label>
</div>
<div class="radio">
<input type="radio" name="a" value="ok_but" v-model="arrayX.item1.value" id="ok_but"/>
<label for="ok_but">Ok but</label>
</div>
<div class="radio">
<input type="radio" name="a" value="ok" v-model="arrayX.item1.value" id="ok"/>
<label for="ok">Ok</label>
</div>
</div>
</template>
<script>
import { mapFields } from 'vuex-map-fields';
export default {
name: 'SwitchColors',
computed:{
...mapFields(['arrayX' ])
}
}
</script>
我在我的 Vue 2 CLI 沙盒应用程序中创建了一个示例场景。每个单选按钮组件通过计算 属性 绑定到 Vuex 存储数组元素。我将存储数组索引值作为 prop 从父级传递给无线电组件。
RadioButtonVuex.vue
<template>
<div class="radio-button-vuex">
<hr>
<div class="row">
<div class="col-md-6">
<input type="radio" value="One" v-model="picked">
<label>One</label>
<br>
<input type="radio" value="Two" v-model="picked">
<label>Two</label>
</div>
</div>
</div>
</template>
<script>
export default {
props: {
pickedIndex: {
type: Number,
required: true
}
},
computed: {
picked: {
get() {
return this.$store.state.radioSelections[this.pickedIndex].picked;
},
set(newValue) {
this.$store.commit('updateSelection', { index: this.pickedIndex, newValue: newValue });
}
}
},
}
</script>
<style scoped>
label {
margin-left: 0.5rem;
}
</style>
Parent.vue
<template>
<div class="parent">
<h3>Parent.vue</h3>
<radio-button-vuex :pickedIndex="0" />
<radio-button-vuex :pickedIndex="1" />
</div>
</template>
<script>
import RadioButtonVuex from './RadioButtonVuex.vue'
export default {
components: {
RadioButtonVuex
}
}
</script>
store/index.js
import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex);
export default new Vuex.Store({
state: {
radioSelections: [
{
picked: 'One'
},
{
picked: 'Two'
}
]
},
mutations: {
updateSelection(state, payload) {
state.radioSelections[payload.index].picked = payload.newValue;
}
}
})
