由于element-ui的弹窗确认组件是封装在message-box中，alert、confirm、prompt统一封装在一起的，那么如果只封装confirm组件要怎么做呢？

话不多说，直接上主干代码！如需了解组件库的边写步骤，请点击前往 Vue组件库开发>>
在 main.js中

import Vue from 'vue';
import Main from './main.vue';

let ConfirmBox = Vue.extend(Main);

// 全局注册组件
Confirm= (content, title, options) => {
    if (typeof title === 'object') {
        options = title;
        title = '';
    } else if (title === undefined) {
        title = '';
    }

    options = Object.assign({
        title: title,
        content: content
    }, options);

    let instance = new ConfirmBox({
        data: options
    }).$mount();

    document.body.appendChild(instance.$el);

    return instance.confirm();
}

export default Confirm;

在 main.vue 中

<template>
    <transition name="fade">
        <div class="confirm-wrap"
            v-if="visible"
            @cllck="closeOnClickModal && close()">
            <div class="confirm">
                <div class="confirm-close"
                    v-if="showClose"
                    @click="close">
                </div>
                <div class="confirm-title" v-show="title">{{ title }}</div>
                <div class="confirm-content">
                    {{ content }}
                </div>
                <div class="confirm-btn">
                    <button v-if="shwoCancelButton"
                        :button-name="cancelButtonText"
                        :button-type="curCancelButtonType"
                        @click="close">
                    </button>
                    <button v-if="shwoConfirmButton"
                        :button-name="ConfirmButtonText"
                        :button-type="curConfirmButtonType"
                        @click="close('confirm')">
                    </button>
                </div>
            </div>
        </div>
    </transition>
</template>

<script>
export default {
    name: 'Confirm',
    data () {
        return {
            visible: false,
            confirmButtonType: '',
            cancelButtonType: '',
            confirmButtonText: '确定',
            cancelButtonText: '取消',
            showCancelButton: true,
            content: '',
            title: '',
            showClose: true,
            showConfirmButton: true,
            closeOnClickModal: false

        }
    },
    computed: {
        curConfirmButtonType () {
            return this.confirmButtonType ? this.confirmButtonType : 'normal'
        },
        curCancelButtonType () {
            return this.cancelButtonType ? this.cancelButtonType : 'cancel'
        }
    },
    methods: {
        confirm () {
            this.visible = true;
            return new Promise((resolve, reject) => {
                this.promiseStatus = { resolve, reject };
            })
        },
        close (val) {
            this.visible = false;
            if (val == 'confirm') {
                this.promiseStatus && this.promiseStatus.resolve();
            } else {
                this.promiseStatus && this.promiseStatus.reject();
            }
        }
    }
}
</script>

调用方法：

this.$Confirm('删除后不可恢复，确定删除此文件？'，‘提示’,{
  confirmButtonText: '删除',
  cancelButtonText: '取消'
}).then(() => {
  // 成功
}).catch(err => {
  // 失败
})

第一次参与组件库的研发与制作，在实现上肯定存在不足的地方，欢迎大家来评论区里留言，感谢大家的批评与指正~
