I have data from the results stored in a child component that needs to be passed to the main component.
The Main Component is the parent, so whenever I click the button, the results should be collected in the main app
<button @click="showFinalResult">Click me</button>The data is currently in the Child component and I just need to display the results in JSON format in the Parent. The results are input results.
results: [],If you want to send data from a child component, you can emit an event:
Vue.component('Child', {
template: `
<div class="">
</div>
`,
data() {
return {
results: [1,2,3]
}
},
mounted() {
this.$emit('update', this.results);
}
})
new Vue({
el: '#demo',
data() {
return {
res: [],
show: false
}
},
methods: {
getResult(res) {
this.res = res
},
showResults() {
this.show = !this.show
}
}
})
