在使用ant design vue的时候,发现有一种消息弹窗可以直接这样调用:
this.$info({
title: 'This is a notification message',
content:'some messages...some messages...'
onOk() {},
});
弹窗
然后我在想,能不能自己也封装一个这种组件,不用每次都import事先写好的组件,能全局调用呢?正好工作中做到一个删除确认框的功能,就研究了一下。
一、创建一个组件(deleteconfirm.vue)
<template>
<a-modal
:title="null"
width="416px"
:bodyStyle="{ padding: '0px' }"
:visible="visible"
:confirm-loading="confirmLoading"
okType="danger"
okText="删除"
:closable="false"
@ok="handleOk"
@cancel="handleCancel"
>
<div class="delete-confirm-wrap">
<div class="title-wrap mb10">
<a-icon
class="mr10"
type="exclamation-circle"
theme="filled"
:style="{ color: '#f9ad15' }"
/>
<span class="confirm-title">{{ title }}</span>
</div>
<div class="warning-title mb10">
删除后相关数据一并删除,此操作不可逆!
</div>
<div class="confirm-tip mb10">如确认删除,请输入:{{ validateText }}</div>
<a-input
class="flex-one"
:placeholder="placeholder"
v-model="userInputText"
/>
</div>
</a-modal>
</template>
<script>
export default {
name: "deleteConfirm",
props: {
title: {
type: String,
default: "您确定要删除吗?",
},
placeholder: {
type: String,
default: "",
},
validateText: {
type: String,
default: "",
},
onOk: {
type: Function,
default() {
return () => {};
},
},
onCancel: {
type: Function,
default() {
return () => {};
},
},
},
data() {
return {
//是否显示
visible: false,
//确定Loading
confirmLoading: false,
//用户输入的确认文案
userInputText: "",
};
},
computed: {},
methods: {
//点击确定按钮
async handleOk() {
//点确定之前校验用户输入的与需要校验的文案是不是一致
if (this.userInputText !== this.validateText) {
this.$message.error("输入错误");
return;
}
this.confirmLoading = true;
//回调用户函数
await this.onOk(this.userInputText);
this.confirmLoading = false;
this.visible = false;
},
//取消按钮
handleCancel() {
this.onCancel("cancel");
this.visible = false;
},
},
};
</script>
<style lang="scss" scoped>
.delete-confirm-wrap {
border-radius: 6px;
height: 170px;
padding: 24px;
.title-wrap {
font-weight: 500;
font-size: 16px;
display: flex;
align-items: center;
}
.warning-title {
color: #ff4d4f;
}
.confirm-tip {
color: #8591a1;
}
}
</style>
二、在该组件同目录下新建index.js
import Vue from 'vue'
//导入组件
import deleteConfirmComp from './deleteconfirm'
//创建构造函数
const deleteConfirmConstructor = Vue.extend(deleteConfirmComp);
//构建删除方法
const deleteConfirm = (options = {}) => {
//动态实例化组件
let instance = new deleteConfirmConstructor({
//此处针对子组件的props进行合并覆盖
propsData: {
...options
}
});
//挂载实例渲染
instance.$mount();
//绑定到body上
document.body.appendChild(instance.$el);
//显示出弹窗
instance.visible = true;
}
//导出该方法
export default deleteConfirm;
三、在main.js中挂载deleteConfirm方法到Vue原型对象上,以便能够全局调用该方法
import Vue from 'vue'
import deleteConfirm from "./components/deleteconfirm/index";
Vue.prototype.$confirm = deleteConfirm;
...
四、使用
this.$confirm({
title: `确定要删除「我叫你一声」吗?`,
placeholder: "请输入要删除的页面名称",
validateText:'我叫你一声',
async onOk() {
//此处是点击确定按钮的回调
...
},
});
