vue页共用一个组件(对话框提示框)

需求是写一个组件(对话框/提示框)
    这个组件的提示内容自定义,其他页面如果使用这个组件的话
    可以引用个组件 自定义对于的内容就可以

    优点是 不用当每个页面需要这个组件时,重写一遍这个方法
    直接可以写一个 多个页面进行使用

对话框

 在components里面写入dialog.vue

<template>
  <div class="dialog">
    <div class="dialog_cover" v-show="dialog"></div>
    <transition name="fade">
      <div class="dialog_content" v-show="dialog">
        <div class="dialog_head">提示</div>
        <div class="dialog_main">{{ message }}</div>
        <div class="dialog_foot">
          <div @click="hide"><span>取消</span></div>
          <div @click="hide"><span>确认</span></div>
        </div>
      </div>
    </transition>
  </div>
</template>
<script>

    },
    message: {
      type: String,

    },
  },
  methods: {
    cancel() {
      this.$emit("hide", null);
    },
  },
};
</script>
<style lang="scss" scoped>

    width: 100%;
    height: 100%;
  }
  //放大再还原的回d动画
  @keyframes move {
    0% {
      transform: scale(0);/*初始0看不到*/
    }
    50% {
      transform: scale(1.1);/*放大*/
    }
    100% {
      transform: scale(1);/*还原*/
    }
  }
  .fade-enter-active {
    //进入
    animation: move 0.5s;
