            <div class="c1" v-for="i in addresslist" 
            :id=i.AddrSeq @click="checkAddress(i.AddrSeq)"
 
>
            </div>

  // 選擇地址
            checkAddress(id) {
                if (this.lastel != null) {
                    this.lastel.style.boxShadow = null
                }
                var el = document.getElementById(id)
                this.lastel = el;
                el.style.
 
boxShadow = ' 0 2px 12px 0 #409EFF'
                this.currentAddress = id;
            },

    .footerstyle {

    }
    .test2 {

data() {
      return {      
      	isChoose:false,
