上篇:vue基于vant的popup组件封装confirm弹框
为什么用到popup呢?主要是用到了其中的动画,其实这个动画可以通过transition标签实现
效果等同于前篇:
step:
1、components文件夹下新建MyConfirm文件夹,分别新建index.vue和index.js
index.vue:<template>
<transition name="my-confirm">
<div class="confirm" v-if="isShow" @click="handleClose()">
<div class="con_box" @click.stop="()=>{}">
<h3>{{text.title}}</h3>
<p>{{text.message}}</p>
<div class="btn">
<span @click.stop="handleClose()" v-if="text.btn.cancelText">{{text.btn.cancelText}}</span>
<span @click.stop="handleOk()" v-if="text.btn.okText">{{text.btn.okText}}</span>
</div>
</div>
</div>
</transition>
</template>
<script>
export default {
data() {
return {
isShow: false,
text: {
title: '提示',
message: '确定删除此条信息?',
btn: {
okText: '确定1',
cancelText: '取消1'
}
}
}
},
methods: {
handleClose() {
console.log('关闭')
},
handleOk() {
console.log('确定')
}
}
}
</script>
<style lang='less' scoped>
.confirm {
background-color: rgba(0, 0, 0, 0.7);
width: 100%;
height: 100%;
position: fixed;
top: 0;
.con_box {
width: 270px;
background: #ffffff;
border-radius: 10px;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
line-height: 1;
text-align: center;
color: #4d5c82;
padding: 15px;
box-sizing: border-box;
> h3 {
font-size: 20px;
margin-top: 10px;
margin-bottom: 20px;
}
> p {
font-size: 17px;
margin-bottom: 30px;
}
.btn {
display: flex;
justify-content: space-between;
> span {
display: block;
width: 114px;
background-color: #e0e5f5;
text-align: center;
line-height: 44px;
font-size: 17px;
}
> span:last-of-type {
background-color: #1288fe;
color: #ffffff;
}
}
}
}
// 命名动画
.my-confirm-enter,
.my-confirm-leave-to {
opacity: 0;
}
.my-confirm-enter-active,
.my-confirm-leave-active {
transition: all 0.8s;
}
</style> index.js:import Vue from 'vue'
import confirm from './index.vue'
let confirmConstructor = Vue.extend(confirm)
let myConfirm = function (text) {
return new Promise((resolve, reject) => {
let confirmDom = new confirmConstructor({
el: document.createElement('div')
})
document.body.appendChild(confirmDom.$el) // new一个对象,然后插入body里面
confirmDom.text = text // 为了使confirm的扩展性更强,这个采用对象的方式传入,所有的字段都可以根据需求自定义
confirmDom.isShow = true
confirmDom.handleOk = function () {
resolve()
confirmDom.isShow = false
}
confirmDom.handleClose = function () {
reject()
confirmDom.isShow = false
}
})
}
export default myConfirm 2、main.js中引入并注册// 自定义confirm
import myConfirm from './components/MyConfirm/index.js'
Vue.prototype.$confirm = myConfirm 3、使用this.$confirm({
title: '提示',
message: '确认删除此篇周计划吗?',
btn: {
okText: '确定1',
cancelText: '取消2'
}
})
.then(() => {
console.log('ok')
})
.catch(() => {
console.log('no')
}) 注意:在index.vue中isShow的初始值为false,在index.js中将该值设置为true。否则会有个bug:显示的时候没有动画而关闭时有动画
