使用组件

<template>
    <div>
        <service-dialog :show.sync="show"></service-dialog>
        <el-button @click="open">click</el-button>
    </div>
</template>
 
<script>
    import serviceDialog from './serviceDialog'
 
    export default {
        data () {
            return {
                show: false
            };
        },
        methods: {
            open () {
                this.show = true;
            }
        },
        components: {
            serviceDialog
        }
    };
