form表單提交是前端經常要用到的，vue.js的form提交只是比普通的多加幾個東西 其他都是大同小異的 上程式碼吧！

主要就是v-model的用法啦 

<form action=""  method="post" enctype="multipart/form-data">
  <div class="add-to">
    <div class="address">
      <p class="address-p">地址</p>
      <select class="address-contry address-s" v-model="formObj.contry">
        <option :value="item.val" v-for="(item,index) in contry" :key="index">{{item.text}}</option>
      </select>
      <select class="address-province address-s" v-model="formObj.province">
        <option :value="item.val" v-for="(item,index) in province" :key="index">{{item.text}}</option>
      </select>
      <select class="address-city address-s" v-model="formObj.city">
        <option :value="item.val" v-for="(item,index) in city" :key="index">{{item.text}}</option>
      </select>
      <select class="address-area address-s" v-model="formObj.area">
        <option :value="item.val" v-for="(item,index) in area" :key="index">{{item.text}}</option>
      </select>
      <input type="text" placeholder="請輸入詳細地址" class="address-text address-s" v-model="formObj.detail"/>
    </div>
    <div class="address-phone">
      <p class="address-num">聯絡方式</p>
      <input type="text" placeholder="請輸入電話號碼" class="address-text address-s" v-model="formObj.phone"/>
    </div>
    <div class="address-div">
      <p class="address-detailed">詳細地址：{{formObj.contry + formObj.province + formObj.city + formObj.area + formObj.detail + ' ' + formObj.phone}}</p>
    </div>
    <div class="number">
      <p class="address-num">數量</p>
      <input type="number" class="number-input" name="points" min="0" max="100" value="1" v-model="formObj.number"/>
    </div>
    <div class="shopping-cart">
      <button class="add-shopping-buy" @click="onSubmit($event)">購買</button>
    </div>
  </div>
</form>
export default {

　　data(){
　　　　return{

formObj:{
  contry:'',
  province:'',
  city:'',
  area:'',
  detail:'',
  phone:'',
  number:''
}

　　 　}
　　}
},

methods:{

onSubmit(event) {
  event.preventDefault();
  let formData = JSON.stringify(this.formObj);
  console.log(formData);
  this.$http.post('', formData).then(function (res) {
    if (res.status === 2000) {

    }
    else{

    }
  })
}

}
