一般调用组件是在各个页面上用标签的形式添加组件，但有时这样会比较麻烦，所以可以使用vue.extend实现，github地址：https://github.com/xyouzi/MessageBox
效果图：
按钮都可用
目录结构：
MessageBox组件的vue文件:
<template>
<div class="mask">
<div class="messageBox">
<h2 class="title">
<p>{
{
title}}</p>
<span @click="handleCancel">×</span>
</h2>
<div class="content">{
{
content}}</div>
<div class="btns">
<div class="btn-ok" @click="handleOk">{
{
ok}}</div>
<div class="btn-cancel" @click="handleCancel">{
{
cancel}}</div>
</div>
</div>
</div>
</template>
<script>
export default {
};
</script>
<style scoped>
* {
box-sizing: border-box;
padding: 0;
margin: 0;
}
.mask {
width: 100vw;
height: 100vh;
position: fixed;
top: 0;
left: 0;
bottom: 0;
right: 0;
background: rgba(0, 0, 0, 0.5);
}
.messageBox {
width: 450px;
height: 220px;
border-radius: 4px;
background: #fff;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
overflow: hidden;
padding: 20px;
}
.title {
display: flex;
justify-content: space-between;
/* 强制不换行 */
white-space: nowrap;
overflow: hidden;
/* 多余文字显示省略号 */
text-overflow: ellipsis;
}
.title span {
cursor: pointer;
}
.content {
height: 100px;
overflow-y: auto;
padding: 5px;
display: flex;
justify-content: center;
align-items: center;
}
.btns {
display: flex;
flex-direction: row-reverse;
margin-top: 20px;
text-align: center;
line-height: 34px;
}
.btn-cancel,
.btn-ok {
width: 80px;
height: 34px;
border: none;
outline: none;
color: #fff;
background-color: #409eff;
border-color: #409eff;
margin-left: 10px;
border-radius: 3px;
cursor: pointer;
}
.btn-cancel {
color: #409eff;
border: 1px solid #409eff;
background-color: #fff;
}
.btn-ok:hover {
background-color: rgb(0, 146, 238);
}
.btn-cancel:hover {
color: #fff;
background-color: rgb(0, 164, 255);
}
</style>
js文件：
import Vue from 'vue';
import MessageBox from './MessageBox';
export let messageBox = (function () {
let defaults = {
// 默认值
title: '',
content: '',
cancel: '取消',
ok: '确定',
handleCancel: null,
handelOk: null
};
let MyComponent = Vue.extend(MessageBox);
return function (opts) {
// 配置参数
for (let attr in opts) {
defaults[attr] = opts[attr];
}
let vm = new MyComponent({
el: document.createElement('div'),
data: {
title: defaults.title,
content: defaults.content,
cancel: defaults.cancel,
ok: defaults.ok
},
methods: {
handleCancel() {
defaults.handleCancel && defaults.handleCancel.call(this);
document.body.removeChild(vm.$el);
},
handleOk() {
defaults.handleOk && defaults.handleOk.call(this);
document.body.removeChild(vm.$el);
}
}
});
document.body.appendChild(vm.$el);
}
})()
可以在main中全局注册，这里我在页面中调用：
<template>
<div id="app"></div>
</template>
<script>
import {
messageBox } from "@/components/youziComs";
export default {
name: "App",
components: {
},
mounted() {
messageBox({
title: "提示",
content: "确定删除吗",
handleCancel() {
console.log(1);
},
handleOk() {
console.log(2);
}
});
}
};
</script>
<style>
</style>
