实现dialog组件

<template>
  <van-overlay :show="visible" class-name="dialog-overlay flex-center">
    <div class="dialog">
      <div class="dialog-container bg-fff width-590 radius-16 flex-start-column">
        <div class="title flex-center" v-if="title">
          <img v-if="isShowIcon" class="tips-icon m-r-10" src="@/assets/service/tishi.png" />
          <div>{{ title }}</div>
        </div>
        <div class="content">{{ message }}</div>
        <div class="html" v-html="htmlContent"></div>
        <div class="footer">
          <div class="btn-group" v-if="!isSingle">
            <div class="btn cancel" @click="cancel">{{ cancelButtonText }}</div>
            <div class="btn confirm" @click="confirm">{{ confirmButtonText }}</div>
          </div>
          <div class="btn-group" v-else>
            <div class="single" @click="confirm">{{ confirmButtonText }}</div>
          </div>
        </div>
      </div>
    </div>
  </van-overlay>
</template>
<script>
export default {
  name: "c-dialog",
  data() {
    return {
      visible: false,
      title: "", // 标题
      message: "",
      htmlContent: "",
      confirmButtonText: "确定",
      cancelButtonText: "取消",
      isSingle: false, // 是否单按钮
      isShowIcon: false, // 是否展示提示icon
      resolve: null,
      reject: null
    };
  },
  methods: {
    open(options) {
      this.title = options.title || this.title;
      this.message = options.message || this.message;
      this.htmlContent = options.htmlContent || this.htmlContent;
      this.confirmButtonText = options.confirmButtonText || this.confirmButtonText;
      this.cancelButtonText = options.cancelButtonText || this.cancelButtonText;
      this.isSingle = options.isSingle || this.isSingle;
      this.isShowIcon = options.isShowIcon || this.isShowIcon;
      this.visible = true;
      return new Promise((resolve, reject) => {
        this.resolve = resolve;
        this.reject = reject;
      });
    },
    close() {
      this.cancel();
    },
    cancel() {
      this.reject();
      this.visible = false;
    },
    confirm() {
      this.resolve();
      this.visible = false;
    }
  }
};
</script>
<style lang="less" scoped>
.dialog {
  margin: 0 auto;
  .dialog-container {
    align-items: center;
    padding: 40px 40px 56px;
  }
  .title {
    height: 44px;
    font-size: 32px;
    font-weight: 600;
    color: #0a0707;
    line-height: 44px;
    font-family: PingFangSC-Medium, PingFang SC;
  }
  .tips-icon {
    width: 28px;
    height: 28px;
  }
  .content {
    font-size: 28px;
    color: #000000;
    line-height: 60px;
    margin-top: 40px;
    font-weight: 400;
    text-align: center;
  }
  .footer {
    margin-top: 60px;
    .btn-group {
      display: flex;
      justify-content: center;
      align-items: center;
    }
    .btn {
      width: 240px;
      height: 80px;
      line-height: 80px;
      border-radius: 16px;
      border: 2px solid #609e39;
      text-align: center;
    }
    .cancel {
      color: #609e39;
    }
    .confirm {
      background: #609e39;
      color: #fff;
      margin-left: 30px;
    }
    .single {
      width: 324px;
      height: 80px;
      line-height: 80px;
      background: #609e39;
      color: #fff;
      border-radius: 40px;
      text-align: center;
    }
  }
}
.dialog-overlay {
  z-index: 3000;
}
</style>

实现install和uninstall方法

import Vue from "vue";
import CDialog from "./index.vue";
import router from "@/router";

const DialogConstructor = Vue.extend(CDialog);

const cDialogPlugin = {
  install(Vue) {
    const instance = new DialogConstructor();
    instance.$mount(document.createElement("div"));
    document.body.appendChild(instance.$el);

    Vue.prototype.$cDialog = {
      open(options) {
        return instance.open(options);
      },
      close() {
        if (instance && instance.visible) {
          instance.close();
        }
      }
    };
  },
  uninstall(Vue) {
    Vue.prototype.$cDialog = null;
  }
};

router.afterEach(() => {
  Vue.prototype.$cDialog && Vue.prototype.$cDialog.close();
});

export default cDialogPlugin;

全局或局部注册

main.js

import CDialog from "@/components/c-dialog/index";

Vue.use(CDialog);
