错误/成功提示

H5内容，项目中有成功、错误的提示，并样式与使用组件不同，刚开始封装成组件的形式，但是使用的时候，需要设置v-model的值或者通过refs的方式来控制提示的显示，不方便，于是我想封装成像element-ui一样的通过this.$message的方式就可以调用，减少调用的复杂度。

1.首先修改组件，用于适应调用方式
参数说明：

• type：提示类型，默认 error，目前只支持error与success
• showCancelButton：是否展示取消按钮
• showConfirmButton：是否展示确认按钮
• confirmButtonText：确认按钮文字
• cancelButtonText：q

<template><van-overlay :show="visible" class="overlay column-flex center-flex" @click="handleOverlayClick"><div class="overlay-wrapper align-center column-flex" @click.stop><img class="overlay-wrapper-error":src="require(`@/assets/images/common/${type === 'error' ? 'error' : 'success'}.png`)" /><p class="color-main mgb-15 overlay-wrapper-tips flex-1">{{ message }}</p><div class="w-100" v-if=" $slots.footer || showCancelButton || showConfirmButton"><slot name="footer"><div class="footer-buttons"><van-button v-if="showCancelButton" size="small" @click="handleAction('cancel')" class="confirm-btn" round type="default">{{ cancelButtonText }}</van-button><van-button v-if="showConfirmButton" size="small" @click="handleAction('confirm')" class="confirm-btn" round type="primary">{{ confirmButtonText }}</van-button></div></slot></div></div><i class="close-icon nm-icon" @click="handleAction('close')"> </i></van-overlay>
</template><script>
export default {name: 'MessageTips',data() {return {visible: false, // 控制显示/隐藏message: '',    // 提示消息内容type: 'error',  // 提示类型，默认 errorshowCancelButton: false, // 是否显示取消按钮showConfirmButton: false, // 是否显示确认按钮confirmButtonText: '确认', // 确认按钮文本cancelButtonText: '取消', // 取消按钮文本distinguishCancelAndClose: false, // 是否区分取消和关闭resolve: null, // Promise resolve 函数reject: null  // Promise reject 函数};},methods: {// 处理按钮点击事件handleAction(action) {this.visible = false; // 关闭弹框if (action === 'confirm') {this.resolve && this.resolve();} else if (action === 'cancel') {this.reject && this.reject('cancel');} else if (action === 'close') {if (this.distinguishCancelAndClose) {this.reject && this.reject('close');} else {this.reject && this.reject('cancel');}}},// 处理遮罩层点击事件handleOverlayClick() {if (this.distinguishCancelAndClose) {this.handleAction('close');} else {this.handleAction('cancel');}},// 显示弹框show(options) {this.message = options.message || '';this.type = options.type || 'error';this.showCancelButton = options.showCancelButton || false;this.showConfirmButton = options.showConfirmButton || false;this.confirmButtonText = options.confirmButtonText || '确认';this.cancelButtonText = options.cancelButtonText || '取消';this.distinguishCancelAndClose = options.distinguishCancelAndClose || false;this.visible = true;// 自动关闭if (options.duration) {setTimeout(() => {this.handleAction('close');}, options.duration);}// 返回 Promisereturn new Promise((resolve, reject) => {this.resolve = resolve;this.reject = reject;});}}
};
</script><style lang="scss" scoped>
.overlay {z-index: 40;&-wrapper {min-height: 150px;max-width: 302px;border-radius: 16px;padding: 13px 21px 19px 21px;background: linear-gradient(180deg, rgba(255, 250, 222, 1) 0%, rgba(255, 253, 245, 1) 41.84%, rgba(255, 255, 255, 1) 72.6%);&-error {width: 70px;height: 70px;object-fit: contain;margin-bottom: 12px;}&-tips {font-size: 14px;line-height: 20px;display: flex;align-items: center;}}.close-icon {width: 40px;height: 40px;margin-top: 25px;background: url(~@/assets/images/common/border-close.png);}.footer-buttons {display: flex;justify-content: space-between;gap: 8px;.confirm-btn + .confirm-btn{margin-left:0;}}
}
</style>

2. 将组件挂载到this.$message，并在main.js中引入

import Vue from 'vue';
import MessageTips from '@/components/messageTips/indexJs.vue'; // 引入组件// 创建插件对象
const messageTips = {install(Vue) {// 创建子类构造函数const MessageTipsConstructor = Vue.extend(MessageTips);// 定义全局方法 $messageVue.prototype.$message = function (options) {// 创建组件实例const instance = new MessageTipsConstructor({propsData: options // 传递 props});// 挂载到 DOMinstance.$mount();document.body.appendChild(instance.$el);// 支持自定义 footer 插槽if (options.footerSlot) {instance.$slots.footer = [options.footerSlot];instance.$forceUpdate(); // 强制更新组件}// 显示弹框并返回 Promisereturn instance.show(options);};}
};// 使用插件
Vue.use(messageTips);

3.使用方式：

• 取消和确认按钮都显示

 this.$message({distinguishCancelAndClose: true,confirmButtonText: '继续录入',cancelButtonText: '前往查看',message: '提示',showCancelButton: true,showConfirmButton: true}).then(() => {console.log('点击保存')}).catch((action) => {// action来区分是点击取消按钮还是关闭按钮console.log('点击关闭', action)});

• 只显示确认按钮

 this.$message({message: '提示',showCancelButton: false,showConfirmButton: true}).then(() => {console.log('点击保存')}).catch(() => {console.log('点击关闭')});

• 成功提示

        handleSuccess() {this.$message({message: '工单处理结果已提交成功！',type: "success",}).catch(() => {console.log('点击关闭')})},

• 自定义底部内容及自动关闭

 const customFooter = this.$createElement('div', {class: 'custom-footer'}, [this.$createElement('van-button', {props: {type: 'primary',size: 'small',round: true},on: {click: () => {this.$message({ message: '你点击了自定义按钮', type: 'success' });}}}, '自定义按钮'),this.$createElement('van-button', {props: {type: 'primary',size: 'small',round: true},on: {click: () => {this.$message({ message: '你点击了自定义按钮', type: 'success' });}}}, '自定义按钮')]);this.$message({message: '这是一个自定义 footer 的提示框',type: 'success',footerSlot: customFooter,duration: 3000}).catch(() => { });
