[英]Passing data from Parent to Child modal - Vue.js
我试图将一些数据从父组件传递到作为模态的子组件。 出于某种原因,向我抛出的错误是“Uncaught TypeError: Cannot set property 'domain' of undefined”。 我正在尝试使用其键传递父组件项,然后在父组件中找到此元素,然后在子组件中找到数据变量。 有人可以告诉我我错过了什么吗? 谢谢!
这是我的父组件 Domain.vue
<template>
<div class="container">
<div class="form-group">
<input type="text" class="form-control" id="filter" placeholder="Filter the Domains">
</div>
<div class="row content-holder">
<table>
<thead>
<tr>
<th class="client-name">Domain</th>
<th class="client-pm">Client</th>
<th class="client-pm">Add Log on Domain</th>
</tr>
</thead>
<tbody>
<tr v-for="domain in domains" :key="domain.id" :domain="domain" class="tr-table">
<td class="client-name">{{ domain.url }}</td>
<td class="client-pm">{{ domain.client }}</td>
<td class="client-pm center"><i class="fas fa-plus jobs-page" data-toggle="modal" @click="openAdd(domain)"></i></td>
</tr>
</tbody>
</table>
</div>
<Add :openmodal="addActive" @closeRequest='close'></Add>
</div>
</template>
<script>
import axios from 'axios';
let Add = require('./Add.vue');
export default {
name:'Domain',
data(){
return {
addActive:'',
domains: [],
domain: {id:'', url:'', client: ''},
errors:{}
}
},
methods:{
getDomains(){
window.axios.get('/develogger-app/public/api/domains').then(({data})=>{
data.forEach(domain =>{
this.domains.push(domain)
});
});
},
openAdd(key){
this.$children[1].domain = this.domains[key];
this.addActive = 'is-active';
},
save(){
},
close(){
this.addActive = '';
},
},
created(){
this.getDomains();
},
components:{
Add
}
}
</script>
这是子组件 Add.vue

},
// computed: {

</script>
您将data
指定为主 Vue 实例中的函数。 它应该是
主 Vue 实例中的一个对象:
data: {
....
}
而组件中的一个函数:
data() {
return {...}
}
见官方参考。
您将data
作为两者的功能。
