使用vue2.0实现一个简单的弹出对话框

<template>
  <div>
    <button @click="openDialog">打开对话框</button>
    <div v-if="showDialog" class="dialog-wrapper">
      <div class="dialog">
        <h2 class="dialog-title">对话框标题</h2>
        <p class="dialog-content">对话框内容</p>
        <button @click="closeDialog" class="dialog-button">关闭</button>
      </div>
    </div>
  </div>
</template>

<style>
.dialog-wrapper {
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  display: flex;
  align-items: center;
  justify-content: center;
  background-color: rgba(0, 0, 0, 0.5);
}

.dialog {
  background-color: white;
  padding: 20px;
  border-radius: 8px;
  box-shadow: 0 2px 4px rgba(0, 0, 0, 0.2);
  max-width: 400px;
  width: 80%;
}

.dialog-title {
  font-size: 20px;
  margin-bottom: 10px;
}

.dialog-content {
  margin-bottom: 20px;
}

.dialog-button {
  background-color: #007bff;
  color: white;
  border: none;
  padding: 10px 20px;
  border-radius: 4px;
  cursor: pointer;
}

.dialog-button:hover {
  background-color: #0056b3;
}
</style>

<script>
export default {
  data() {
    return {
      showDialog: false
    };
  },
  methods: {
    openDialog() {
      this.showDialog = true;
    },
    closeDialog() {
      this.showDialog = false;
    }
  }
};
</script>
