vue-observable （拟vuex）

Vue.observable( object )

1.创建 /src/store.js

import Vue from 'vue'
export const store = Vue.observable({
    url: {},
    user: {}
});
export const mutations = {
    setUrl(data) {
        store.url = data;
    },
    setUser(data) {
        store.user = data;
    }
}
export default {
    store,
    mutations
}

window.addEventListener('beforeunload', () => {
    sessionStorage.setItem('StoreUrl', JSON.stringify(store.url));
    sessionStorage.setItem('StoreUser', JSON.stringify(store.user));
});
mutations.setUrl(JSON.parse(sessionStorage.getItem('StoreUrl')));
mutations.setUser(JSON.parse(sessionStorage.getItem('StoreUser')));
sessionStorage.removeItem('StoreUrl');
sessionStorage.removeItem('StoreUser');

2.修改 /src/main.js

import store from './store'
Vue.prototype.$store = store;
