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
    }
  }
};

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>

      <button @click.stop="showModel_6 = true">
        设置3秒后自动关闭
