我有一个Vue文件,看起来像这样:
import store from '@/store'
export default{
name: 'myList',
data: () => ({
show: true,
listContent: [{
name: '1',
icon: 'person',
value: function () {
return store.state.myStore.settings.one
}
}, {
name: '2',
icon: 'person',
value: function () {
return store.state.myStore.settings.two
}
}, {
name: '3',
icon: 'person',
value: function () {
return store.state.myStore.settings.three
}
}
]
})
}
不起作用的部分是从“ listContent”中获取“值”。
{
name: '3',
icon: 'person',
value: function () {
return store.state.myStore.settings.three
}
}
在我的代码中,我已导入视图,就好像要放入:
this.$store.state.myStore.settings.one
在值函数中,“ this”将引用对象
{
name: '3',
icon: 'person',
value: function () {
return store.state.myStore.settings.three
}
}
我无法去商店。但是,我的代码仍然无法正常工作。我需要访问listContent内的商店。
列表的呈现方式如下:
<v-data-table :items="listContent" hide-actions hide-headers>
<template slot="items" slot-scope="props">
<td>{{ props.item.name }}</td>
<td class="text-xs-right" v-text="props.item.value()"> </td>
</template>
</v-data-table>
我未正确引用商店,或模板不正确。有什么想法吗?

为什么要让value
是一个返回状态值的函数。您可以使用state
this.$store.state.myStore.settings.one
值
为此,请将data
选项设置为普通功能而不是箭头功能,以便this
仍表示vue实例
export default {
name: "myList",
data() {
return {
show: true,
listContent: [
{
name: "1",
icon: "person",
value: this.$store.state.myStore.settings.one
},
{
name: "2",
icon: "person",
value: this.$store.state.myStore.settings.two
},
{
name: "3",
icon: "person",
value: this.$store.state.myStore.settings.three
}
]
};
}
};

也许这会有所帮助。长了一个,但是行得通。
const myModule = {
state: {
test: "modulle",
settings: {
one: "This is one",
two: "This is two",
three: "This is three"
}
}
};
const store = new Vuex.Store({
modules: { myModule }
});
new Vue({
el: "#app",
store,
data() {
return {
listContent: [
{
name: "1",
icon: "person",
value: null
},
{
name: "2",
icon: "person",
value: null
},
{
name: "3",
icon: "person",
value: null
}
]
};
},
watch:{
'$store.state.myModule.settings.one':{
immediate:true,
handler:function(value){
this.listContent[0].value = value;
}
},
'$store.state.myModule.settings.two':{
immediate:true,
handler:function(value){
this.listContent[1].value = value;
}
},
'$store.state.myModule.settings.three':{
immediate:true,
handler:function(value){
this.listContent[2].value = value;
}
},
}
});
