此刻我无法解决这个问题。主要父组件不呈现子组件。加载页面时不会引发错误。
到目前为止我有这个代码:
HTML:
<td class="countries-visible-filter">
<visible-filters>
<show-query-filter :selected ="true" query="all" name="All | "></show-query-filter>
<show-query-filter query="true" name="Visible | "></show-query-filter>
<show-query-filter query="false" name="Hidden"></show-query-filter>
</visible-filters>
父组件:
Vue.component('visible-filters', {
template: `
<div>
<span v-for="filter in queryFilters"
:class="{'text-muted' : !filter.isSelected}"
@mouseenter="changeClassMouseenter($event)"
@mouseout="changeClassMouseout($event)"
@click="countryTest(filter)"
>
{{filter.name}}
</span>
</div>
`,
methods: {
countryTest(filter) {
this.filters.forEach(singleFilter => {
console.log(singleFilter);
});
Event.$emit('country-filter', filter);
}
},
created() {
console.log(this);
this.queryFilters = this.$children;
},
data() {
return {
queryFilters: []
}
}
});
子组件:
Vue.component('show-query-filter', {
template: `
<div><slot></slot></div>
`,
props: {
query: '',
selected: false,
name: {required: true}
},
mounted() {
this.isSelected = this.selected;
},
methods: {
changeClassMouseenter(event) {
if(!this.selected)
event.target.classList.remove('text-muted')
},
changeClassMouseout(event) {
if(!this.selected)
event.target.classList.add('text-muted')
}
},
data() {
return {
isSelected: false
}
}
});
我在这里做错了什么?
答案 0 :(得分:2)
这种结构:
<visible-filters>
<show-query-filter :selected ="true" query="all" name="All | "></show-query-filter>
<show-query-filter query="true" name="Visible | "></show-query-filter>
<show-query-filter query="false" name="Hidden"></show-query-filter>
</visible-filters>
表示show-query-filter
的三个实例被用作slot
的内容,但visible-filters
未在其模板中使用slot
定义。
您已定义show-query-filter
以获得slot
,但您不会为其提供任何内容。目前尚不清楚您的预期结果是什么。请注意,插槽内容不是放入插槽的组件的子节点。
