export default {
    data() {
        return {
            value: 0,
        };
    },
    methods: {
        change() {
            this.value++;
        },
    },
    mounted() {
        window.addEventListener('click', () => this.change());
    },
}

data(){
    return{
        someData: 'aaa'
    }
},
created(){
    let _self = this;
    window.addEventListener('click',function(){
        _self.someData = 'bbb'
        _self.someMethod()
    })
},
methods: {
    someMethod(){
        alert(1)
    }
}
