这篇文章给大家分享的是有关Vue如何实现模态框的内容。小编觉得挺实用的,因此分享给大家做个参考,一起跟随小编过来看看吧。
项目基础工程文件是使用vue-cli3.0搭建的,这里不过多介绍。开发Vue组件系列之模态框,主要有标题、内容、定时器、按钮文案、按钮事件回调、遮罩层这些可配置项。本次开发得组件是本系列的第一个组件,后期也会有更多系列教程推出。
使用命令行
$ Vue create echi-modal
$ cd echi-modal
$ npm install
$ npm run serve
$ npm run build
$ npm run lint
添加vue.config.js文件,配置如下
const path = require("path");
function resolve(dir) {
return path.join(__dirname, dir);
}
module.exports = {
// 基本路径
publicPath: "./",
// eslint-loader 是否在保存的时候检查
lintOnSave: false,
// webpack配置
// see https://github.com/vuejs/vue-cli/blob/dev/docs/webpack.md
chainWebpack: config => {
config.resolve.alias
.set("@", resolve("src"))
},
// 生产环境是否生成 sourceMap 文件
productionSourceMap: false,
// css相关配置
css: {
// 是否使用css分离插件 ExtractTextPlugin
extract: true,
// 开启 CSS source maps?
sourceMap: false,
// css预设器配置项
loaderOptions: {},
// 启用 CSS modules for all css / pre-processor files.
modules: false
},
// use thread-loader for babel & TS in production build
// enabled by default if the machine has more than 1 cores
parallel: require("os").cpus().length > 1,
devServer: {
port: 9595, // 端口号
open: true, // 自动开启浏览器
compress: true, // 开启压缩
overlay: {
warnings: true,
errors: true
}
}
};

modal组件模板
使用 transition 可以为组件添加动效;对应的组件模板内容如下
<template>
<transition name="toggle">
<section class="modal" v-show="visible">
<div class="modal-mask" v-show="showMask" @click="clickMask"></div>
<section class="modal-content modal-center" :>
<header class="modal-header" :class="{ 'modal-plain': plain }" v-if="showHeader">
<slot name="header">{{ title }}</slot>
<span class="closed" v-if="showClose" @click.stop="onClose">
关闭
</span>
</header>
<main class="modal-body">
<slot>
<div class="text-tips">{{ text }}</div>
</slot>
</main>
<footer class="modal-footer" v-if="showFooter">
<slot name="footer">
<button class="modal-btn modal-btn-primary" @click.stop="onConfirm">
{{ confirmBtnText }}
</button>
<button class="modal-btn modal-btn-default" @click.stop="onClose">
{{ cancelBtnText }}
</button>
</slot>
</footer>
</section>
</section>
</transition>
</template>
添加组件属性及操作方法
添加组件的属性,其中duration属性如果设定的数值小于10,则会乘以1000;否则按传递的数值计算
<script>
export default {
name: "EchiModal",
props: {
visible: {
type: Boolean,
default: false
},
title: {
type: String,
default: "标题"
},
text: {
type: String,
default: "提示信息"
},
tinyBar: {
type: Boolean,
default: false
},
confirmBtnText: {
type: String,
default: "确定"
},
cancelBtnText: {
type: String,
default: "返回"
},
contentStyle: {
type: Object,
default: () => {}
},
showClose: {
type: Boolean,
default: true
},
plain: {
type: Boolean,
default: false
},
showHeader: {
type: Boolean,
default: true
},
showFooter: {
type: Boolean,
default: true
},
showMask: {
type: Boolean,
default: true
},
onMask: {
type: Boolean,
default: false
},
duration: {
type: Number,
default: 0
}
},
watch: {
visible(nv) {
if (nv) {
this.closeTimerHandle()
}
}
},
data() {
return {
closeTimer: null,
}
},
methods: {
onClose() {
this.$emit("on-close");
this.hide();
},
onConfirm() {
this.$emit("on-confirm");
},
hide() {
this.$emit("update:visible", false);
this.$emit("on-closed");
clearTimeout(this.closeTimer);
this.closeTimer = null;
},
clickMask() {
if (this.onMask && this.showMask) {
this.hide();
}
},
closeTimerHandle() {
try {
if (this.duration <= 0) {
return;
}
const duration = (this.duration < 10) ? (this.duration * 1000) : this.duration;
clearTimeout(this.closeTimer);
this.closeTimer = setTimeout(() => {
this.onClose();
}, duration);
} catch (e) {
console.log(e)
}
}
}
};
</script>
添加样式声明
<style scoped lang="scss">
