vue——公用方法

1. 新建methods.js

export function alertMessage(txt) {
    alert(txt)
}

2. 组件中引入并使用

<template>
    <div>
        <button @click="alertMessage(111)">弹窗</button>
    </div>
</template>

<script>
    import {alertMessage} from "../../assets/js/methods";
    
    export default {
        data() {
            return {
                alertMessage
            }
        }
    }
<script>
