How can I stay informed about any changes in Banana.vue?
I have tried using addEventListener, @watch but it doesn't seem to be working...
The index.vue file is importing both Apple.vue and Banana.vue
In Apple.vue:
localStorage.setItem('fruit', 'apple)In Banana.vue:
@watch(localStorage.getItem('fruit' || '')
changeFruit() {
this.fruit = localStorage.getItem('fruit')
}Implement the getter and setter methods in your code.
data() {
return {
get token() {
return localStorage.getItem('token') || 0;
},
set token(value) {
localStorage.setItem('token', value);
this.fruit = localStorage.getItem('fruit')
}
};
}
LocalStorage might not be reactive, but you can still retrieve the localStorage value within the component using this approach :
Vue.component('apple', {
props: ['childmsg'],
template: '<p>{{ childmsg }}</p>',
mounted() {
localStorage.setItem('fruit', 'apple');
}
});
Vue.component('banana', {
data: {
fruit: ''
},
props: ['childmsg'],
template: '<p>{{ childmsg }}</p>',
mounted() {
if (localStorage.fruit) {
this.fruit = localStorage.fruit;
console.log(this.fruit);
}
}
});
var app = new Vue({
el: '#app'
});<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<apple childmsg="This is Apple"></apple>
<banana childmsg="This is Banana"></banana>
