我的案例
我有两个组成部分,父母和子组件
我的父组件:
<template>
...
<div class="row">
...
<location-select level="continentList" type="1"/>
...
<location-select level="countryList" type="2"/>
...
<location-select level="cityList" type="3"/>
...
</div>
</template>
<script>
...
export default{
...
}
</script>
父组件是模态bootstrap
我的孩子组成部分:
<template>
<select class="form-control" v-model="selected" @change="changeLocation">
<option value="0" disabled>Select</option>
<template v-for="option in options">
<option v-bind:value="option.id" >{{ option.name }}</option>
</template>
</select>
</template>
<script>
...
export default{
props: ['level','type'],
data() { return { selected: '' };},
computed:{
...mapGetters([
'getContinentList', 'getCountryList','getCityList'
]),
options(){
const n = ['getContinentList', 'getCountryList','getCityList']
return this[n[this.type-1]]
}
},
methods:{
...mapActions([
'getLocationList'
]),
changeLocation(event){
if(this.type==1){
this.getLocationList([{type:2},{level:'countryList'}])
this.getLocationList([{type:3},{level:'cityList'}])
}else if(this.type==2){
this.getLocationList([{type:3},{level:'cityList'}])
}
}
},
created() {
if(this.type==1)
this.getLocationList([{type:1},{level:'continentList'}])
if(this.type==2 && this.selected!='')
this.getLocationList([{type:2},{level:'countryList'}])
if(this.type==3 && this.selected!='')
this.getLocationList([{type:3},{level:'cityList'}])
},
mounted() {
$(this.$parent.$refs.modal).on('hidden.bs.modal', (e) => {
Object.assign(this.$data, this.$options.data())
})
},
};
</script>
如果模态秀,我选择了大陆,乡村和城市。然后我关闭模态
之后,我再次显示模式。然后我首先选择国家和城市,数据仍然存在
我想重置数据。因此,如果我再次打开模式,在我选择大陆之前,国家和城市数据未显示
我尝试:
Object.assign(this.$data, this.$options.data())
和此:
Object.assign(this.$data,this.$options.data.call(this))
也是如此:
this.$forceUpdate()
模态隐藏
但是,它不起作用
似乎必须更新数据computed:{...}
。但是我仍然为此感到困惑
如何解决此问题?
您是否尝试过重置mounted
LifeCycle Hook中的selected
数据属性?
...
mounted() {
let $vm = this;
$(this.$parent.$refs.modal).on('hidden.bs.modal', (e) => {
$vm.selected = '';
});
},
...
只是v-if f-if模态组件,切换时它将恢复/重新计算所有内容。
父母的父母:
<template>
<div class="parent-of-parent">
<your-modal-component v-if="isModalOpened" @close="closeModal"></your-modal-component>
</div>
</template>
<script>
export default{
data() {
return { isModalOpened: false };
},
methods: {
openModal() {
this.isModalOpened = true;
}, // method to open it
closeModal() {
this.isModalOpened = false;
}, // method to attach to emit event from modal on close
},
};
</script>
请确保将单击事件连接到您单击的图标上,以获取关闭或其他内容。并将一种方法附加到这样的事件中。
this.$emit('closeModal');
如果您在动画模态有问题的情况下使用<transition>
<transition name="fadeIn">
<your-modal-component v-if="isModalOpened" @close="closeModal"></your-modal-component>
</transition>
