吐司组件在前端中算是最常用的组件了,这里简单实现一下;
# 封装toast组件
ui部分,主要是显示内容;
<template>
<div class="w-toast" v-show="visible">
<span class="w-toast-title">{{ title }}</span>
<slot>
<p class="w-toast-content">{{ content }}</p>
</slot>
</div>
</template>
<script>
export default {
name: 'WToast',
props: {
title: String,
content: String,
duration: {
default: 3000
}
},
data() {
return {
visible: false,
}
},
methods: {
open() {
this.visible = true;
setTimeout(this.close, this.duration);
},
close() {
this.visible = false;
this.remove();
}
}
}
</script>
<style scoped>
.w-toast {
position: fixed;
left: 50%;
top: 20%;
max-width: 300px;
height: 40px;
line-height: 40px;
padding: 0 20px;
transform: translateX(-50%);
background: #ccc;
}
.w-toast-content {
margin: 0;
display: inline-block;
}
</style>

# 创建create函数
方法用于随时创建使用 toast 提示;
import Vue from 'vue';
// 方式一
function create(component, props) {
// 完成vue的初始化但是没有要挂载的节点;
const _vm = new Vue({
render(h) {
return h(component, { props })
}
}).$mount();
// 挂载到 body 节点上
document.body.appendChild(_vm.$el);
// 给组件示例添加销毁方法;
const comp = _vm.$children[0];
comp.remove = () => {
document.body.removeChild(_vm.$el);
_vm.$destroy();
}
return comp;
}
// 方式二;
function create(component, props) {
const Ctor = Vue.extend(component)
const comp = new Ctor({ propsData: props });
comp.$mount();
document.body.appendChild(comp.$el);
// 给组件示例添加销毁方法;
comp.remove = () => {
document.body.removeChild(comp.$el);
comp.$destroy();
}
return comp;
}
export default create;
