<template>
  <view>

      <text>{{ activity.name }}</text>
      <button @click="gotoSignup(activity.id)">报名</button>
    </view>
  </view>
</template>

<script>
export default {
  data() {
    return {
      activities: [
        { id: 1, name: '活动1' },
        { id: 2, name: '活动2' },
      ],
    };
  },
  methods: {
    gotoSignup(activityId) {
      uni.navigateTo({
        url: '/pages/signup?id=' + activityId,
      });
    },
  },
};
</script>

    <input v-model="name" placeholder="姓名" />
    <input v-model="contact" placeholder="联系方式" />

<script>
export default {
  data() {
    return {
      name: '',
      contact: '',
    };
  },
  methods: {
    signup() {
      // 根据活动id和用户信息进行报名操作
    },
  },
};
</script>

<template>
  <view>
    <text>{{ activity.name }}</text>
    <text>已报名人数：{{ activity.signupCount }}</text>
  </view>
