vue实现点击按钮弹窗

你可以使用Vue.js框架中的模态框组件来实现点击按钮弹窗的功能。以下是一个简单的示例：

1. 在你的Vue组件中，引入模态框组件：

<template>
  <div>
    <button @click="showModal = true">点击弹窗</button>
    <modal v-if="showModal" @close="showModal = false">
      <h3>这是一个弹窗标题</h3>
      <p>这是弹窗的内容</p>
    </modal>
  </div>
</template>

<script>
import Modal from './Modal.vue';

export default {
  components: {
    Modal
  },
  data() {
    return {
      showModal: false
    }
  }
}
</script>

2. 创建一个模态框组件Modal.vue：

<template>
  <div class="modal-mask">
    <div class="modal-wrapper">
      <div class="modal-container">
        <div class="modal-header">
          <slot name="header"></slot>
          <button class="modal-close-btn" @click="$emit('close')">关闭</button>
        </div>
        <div class="modal-body">
          <slot></slot>
        </div>
      </div>
    </div>
  </div>
</template>

<script>
export default {
  name: 'modal'
}
</script>

<style>
/* 模态框样式 */
.modal-mask {
  position: fixed;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
  background-color: rgba(0, 0, 0, 0.5);
  z-index: 9998;
}
.modal-wrapper {
  display: table;
  width: 100%;
  height: 100%;
}
.modal-container {
  display: table-cell;
  vertical-align: middle;
  text-align: center;
}
.modal-header {
  margin-bottom: 10px;
  font-size: 18px;
  font-weight: bold;
  color: #333;
}
.modal-close-btn {
  position: absolute;
  top: 10px;
  right: 10px;
  padding: 5px 10px;
  border: none;
  background-color: #ddd;
  cursor: pointer;
}
.modal-body {
  padding: 20px;
  font-size: 16px;
  color: #666;
}
</style>

3. 在你的CSS文件中添加以下样式来美化模态框：

/* 模态框样式 */
.modal-mask {
  position: fixed;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
  background-color: rgba(0, 0, 0, 0.5);
  z-index: 9998;
}
.modal-wrapper {
  display: table;
  width: 100%;
  height: 100%;
}
.modal-container {
  display: table-cell;
  vertical-align: middle;
  text-align: center;
}
.modal-header {
  margin-bottom: 10px;
  font-size: 18px;
  font-weight: bold;
  color: #333;
}
.modal-close-btn {
  position: absolute;
  top: 10px;
  right: 10px;
  padding: 5px 10px;
  border: none;
  background-color: #ddd;
  cursor: pointer;
}
.modal-body {
  padding: 20px;
  font-size: 16px;
  color: #666;
}

4. 运行你的Vue应用程序，点击按钮就可以弹出模态框了。
