Vue组件系列开发之模态框

网络
掉漆的栏杆上，反射着夕阳的余晖渐渐消逝。我们的青春就随这样随着夕阳落幕。绮丽多姿扮靓妆，繁花锦簇沁心香。长歌游宝地，徒倚对珠林。家门口的风景，其实眼前的就是最好的，爱你选择的一切!

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好代码教程推出。

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
 }
 }
};

部分截图

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" :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">
   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>

  显示素样式
  </button>
  <button @click.stop="showModel_2 = true">
  修改提示语

  <button @click.stop="showModel_3 = true">
  自定义内容

  <button @click.stop="showModel_4 = true">
  去除Footer
  </button>
  <button @click.stop="showModel_5 = true">
  去除Header
  </button>
  <button @click.stop="showModel_6 = true">
  设置3秒后自动关闭
  </button>
 </div>
 <EchiModal :visible.sync="showModel_0" title="显示默认样式"></EchiModal>
 <EchiModal :visible.sync="showModel_1" title="显示素样式" plain></EchiModal>
 <EchiModal :visible.sync="showModel_2" title="修改提示语" text="哈哈哈哈哈,我把提示信息修改了"></EchiModal>
