今日目標
按下分享經驗後跳出表單，填寫完後按分享經驗按鈕就可以囉

實作分享表單

在 src/components 中新增 NewPostModal.vue

<script setup>
import { ref, reactive } from 'vue'

const props = defineProps({
  visible: { type: Boolean, default: false }
})

const emit = defineEmits(['close', 'submit'])

const isSubmitting = ref(false)

const formData = reactive({
  pSchool: '',
  pDep: '',
  pYear: '',
  pScore: '',
  pGPA: '',
  pExp: '',
  pResult1: '',
  pURL: ''
})

function close() {
  emit('close')
  resetForm()
}

function resetForm() {
  Object.keys(formData).forEach(key => {
    formData[key] = ''
  })
}

async function submitExperience() {
  if (isSubmitting.value) return
  
  isSubmitting.value = true
  
  try {
    const newExperience = {
      pId: `p_${Date.now()}`,
      pDate: new Date().toLocaleDateString('zh-TW', {
        year: 'numeric',
        month: '2-digit',
        day: '2-digit'
      }).replace(/\//g, '/'),
      pDcardId: null,
      pURL: formData.pURL || null,
      pYear: formData.pYear,
      pContent: `背景：
學校/系所：${formData.pSchool} ${formData.pDep}
${formData.pScore ? `成績排名：${formData.pScore}` : ''}
${formData.pGPA ? `GPA：${formData.pGPA}` : ''}

經歷：
${formData.pExp}

結果：
${formData.pResult1}`,
      pSchool: formData.pSchool,
      pDep: formData.pDep,
      p_sd_sId: "user_submitted",
      p_sd_dId: "user_submitted",

      pGPA: formData.pGPA || null,
      pExp: formData.pExp,
      pResult1: formData.pResult1
    }
    
    emit('submit', newExperience)
    
    alert('感謝你的分享！你的經驗已成功加入資料庫 ✨')
    
    close()
  } catch (error) {
    console.error('提交失敗:', error)
    alert('提交失敗，請稍後再試')
  } finally {
    isSubmitting.value = false
  }
}
</script>

修改 App.vue

<script setup>
import NewPostModal from './components/NewPostModal.vue'
...
const showShareModal = ref(false)
const allPosts = ref([...posts])

function openShareModal() {
  showShareModal.value = true
}

function handleNewExperience(newExperience) {
  allPosts.value.unshift(newExperience)
  showShareModal.value = false
  keyword.value = ''
  currentPage.value = 1
}
...
</script>

<template>
  <Header @share="openShareModal" />
  <main>
      ...
    <NewPostModal :visible="showShareModal" @close="showShareModal=false" @submit="handleNewExperience" />
  </main>
</template>

修改原本的分享經驗按鈕

<template>
  <header class="header">
    <div class="header-content">
      <h1 class="logo">
        ✦ 推甄經驗分享 ✦
      </h1>
      <button class="add-btn" @click="handleShare">
        ✍ 分享經驗
      </button>
    </div>
  </header>
</template>


<script setup>
  const emit = defineEmits(['share'])

  function handleShare() {
    emit('share')
  }
</script>

但是目前還沒接到資料的 API，所以資料只會暫時新增上去

ref 和 reactive

ref

• 適合單一值，例如: string、number 和 boolean
• 會回傳一個物件，值放在 .value 裡
• 在 templat 裡用 ref，則不需要加上 .value

import { ref } from 'vue'

const count = ref(0)     
console.log(count.value) // 讀寫要用 .value
count.value++

<template>
  <button @click="count++"> {{ count }} </button> <!-- 在模板可直接用 -->
</template>

reactive

• 適合物件、陣列，像是表單、清單等等
• 會回傳一個 Proxy（代理），屬性存取都被 Vue 追蹤
• 不需要 .value，直接用屬性就好

import { reactive } from 'vue'

const form = reactive({
  school: '',
  dep: '',
  year: ''
})

form.school = '台大' // 直接改屬性

<template>
  <input v-model="form.school" placeholder="學校"/>
  <p>輸入的學校是：{{ form.school }}</p>
</template>

小結

• 實作新增資料功能
• ref 與 reaactive 差異
