Access parent methods from component template in vuejs

Question

I have this code:

     new Vue({
        el: '#app',
        components: {
            'app-component': AppComponent
        },
        data: {
            message: 'Hello Vue.js!'
        },
        methods: {
            doSomething: function(){
                console.log('arrived!')
            }
        }
    })

How can I call "doSomething" method from AppComponent html template? like this:

<app-component>  
    <a href="#" v-on:click="doSomething()">text</a>
</app-component>

I get this error:

Uncaught TypeError: scope.doSomething is not a function

Answer 1

试试v-on:click="$parent.doSomething()"

Answer 2

You can use $dispatch from the child to trigger an event. Example:

// App component
<app-component>  
    <a href="#" v-on:click.prevent="$dispatch('do-something')">text</a>
</app-component>


// Parent
new Vue({
    el: '#app',
    components: {
        'app-component': AppComponent
    },
    data: {
        message: 'Hello Vue.js!'
    },
    events: {
        'do-something': function(){
            console.log('arrived!')
        }
    }
});

您可以根据此答案使用此功能。

this.$parent.$options.methods.someParentMethod(data)

Answer 4

In addition to Wiljan response, I extend all components with new Vue instance that has methods and data. Now I access to methods and etc.
