仅当recaptcha已解决且用户复选框已选中时，Vue才应发送邮件

<template>
  <div>
    <input type="checkbox" v-model="isChecked" @change="sendEmail" />
    <div v-if="isChecked && isRecaptchaSolved">
      <!-- 邮件发送的相关表单和内容 -->
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      isChecked: false,
      isRecaptchaSolved: false,
    };
  },
  methods: {
    sendEmail() {
      if (this.isChecked && this.isRecaptchaSolved) {
        // 发送邮件的逻辑代码
      }
    },
  },
};
</script>
