Vue.js 组件在 data 属性中调用一个方法

Question

I'd like to assign component methods to data variables, see the example code below. Sadly it does not work, what is the correct way?

<li v-for="item in items" @click="item.action">
    {{ item.title }}
</li>

export default {
    data: () => ({
        items: [
            { title: "One", action: this.funcOne },
            { title: "Two", action: this.funcTwo },
        ]
    }),
    methods: {
        funcOne() {
            alert("Hi")
        },
        funcTwo() {
            alert("Hello")
        }
    }
}

Try to pass the vue instance ( this ) as parameter to the data function data: (vm) => then use it action: vm.funcOne

 Vue.config.devtools = false; Vue.config.productionTip = false; new Vue({ el: '#app', data: (vm) => ({ // vm the component instance this items: [ { title: "One", action: vm.funcOne}, { title: "Two", action: vm.funcTwo }, ] }), methods: { funcOne() { alert("Hi") }, funcTwo() { alert("Hello") } } })
