例如自定义变量：callbackdata
父组件：
<template>
<div class="top">
<div class='nav'>
<ul class='navHader'>
<li @click="current='Sunyi'" :class="{active:current=='Sunyi'}">损益完成情况分析表</li>
<li @click="current='Caiwu'" :class="{active:current=='Caiwu'}">财务快报资产分析表</li>
<li @click="current='Jingying'" :class="{active:current=='Jingying'}">经营指标完成情况分析表</li>
</ul>
<Menus></Menus>
</div>
<keep-alive>
<component :is="current" :callbackdata="callbackdata"></component>
</keep-alive>
</div>
</template>
<script>
import Menus from "./Button.vue"
import Sunyi from "./Tables/Sunyi.vue"
import Jingying from "./Tables/Jingying.vue"
import Caiwu from "./Tables/Caiwu.vue"
export default {
data() {
return {
current: 'Sunyi',
navs: [
'损益完成情况分析表',
'财务快报资产分析表',
'经营指标完成情况分析表',
],
callbackdata:{},//返回数据
}
},
mounted() {
this.toggleSwitch(this.current)
},
methods: {
toggleSwitch(parameter) {
const self = this;
let this_toggle = parameter;
switch (this_toggle) {
case 'Sunyi':
self.toggleDatainit('pl');
break;
case 'Caiwu':
self.toggleDatainit('bs');
break;
case 'Jingying':
self.toggleDatainit('t1');
break;
}
},
toggleDatainit(talbel_url) {
const self = this;
self.$http.get('getInitTable/init/'+talbel_url).then(res => {
if(res.data.status == 2000){
console.log(res.data);
self.callbackdata = res;
}
}).then(error => {
});
},
},
components: {
Menus,
Sunyi,
Caiwu,
Jingying
},
watch:{
current(newV){
this.toggleSwitch(newV);
}
}
}
</script>
子组件：
<script>
import Tools from '../../tools/tools'
export default {
data() {
return {
HT: new Tools(),// 实例一个对象
HTobjData: '',// HT的一个大集合
}
},
props: {
callbackdata: {
type: Object,
default: {}
}
},
mounted() {
},
methods: {
init(callbackdata) {
const self = this;
self.HTobjData = self.HT.init(callbackdata, self, Handsontable);
}
},
components: {},
//深度监听才能生效
watch: {
callbackdata: {
handler(newVal) {
//alert('call---'+newVal.questionId);
//alert('call---'+newVal);
alert("---call----"+callbackdata.questionId);
//TODO
},
deep: true,
immediate: true
}
}
</script>
以上通过监视变量callbackdata的变化，来达到父组件控制子组件
