開發Vue元件系列之模態框
專案基礎工程檔案是使用vue-cli3.0
搭建的,這裡不過多介紹。開發Vue元件系列之模態框,主要有標題、內容、定時器、按鈕文案、按鈕事件回撥、遮罩層這些可配置項。本次開發得元件是本系列的第一個元件,後期也會有更多系列教程推出。
使用命令列
$ Vue create echi-modal $ cd echi-modal $ npm install $ npm run serve $ npm run build $ npm run lint 複製程式碼
新增vue.config.js檔案,配置如下
const path = require("path"); function resolve(dir) { return path.join(__dirname, dir); } module.exports = { // 基本路徑 publicPath: "./", // eslint-loader 是否在儲存的時候檢查 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")) }, // 生產環境是否生成 sourceMap 檔案 productionSourceMap: false, // css相關配置 css: { // 是否使用css分離外掛 ExtractTextPlugin extract: true, // 開啟 CSS source maps? sourceMap: false, // css預設器配置項 loaderOptions: {}, // 啟用 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,// 埠號 open: true, // 自動開啟瀏覽器 compress: true, // 開啟壓縮 overlay: { warnings: true, errors: true } } }; 複製程式碼

modal元件模板
使用transition
可以為元件新增動效;對應的元件模板內容如下
<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" :style="contentStyle"> <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"> 關閉 </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> 複製程式碼
新增元件屬性及操作方法
新增元件的屬性,其中duration
屬性如果設定的數值小於10,則會乘以1000;否則按傳遞的數值計算
<script> export default { name: "EchiModal", props: { visible: { type: Boolean, default: false }, title: { type: String, default: "標題" }, text: { type: String, default: "提示資訊" }, tinyBar: { type: Boolean, default: false }, confirmBtnText: { type: String, default: "確定" }, 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> 複製程式碼
新增樣式宣告
