2.js代码
<script type="text/javascript">
var app = new Vue({
el:"#app",
data: {
    AdrList :{
      'id':'' ,
      'phone':'',
      'name':'',
      'province':'',
      'city':'',

      if(id>0){
          var loading = layer.load();
          $.post("/shop/member/user/member",{'_token':'{{csrf_token()}}',class:'adrOne',id:id},function (res) {
              if(res.code){
                app.AdrList = res.data;
                console.log(res.data)//后台没问题，前台取到的市、区确实undefined

              } else {
                  layer.msg(res.data);
              }
              layer.close(loading);
          });
      }
    },

      this.initialize();//自动执行
  },
});

Answer 1

$.post("/shop/member/user/member",{'_token':'{{csrf_token()}}',class:'adrOne',id:id},function (res) {

              if(res.code){
                app.AdrList = res.data;
                $('#address-form').distpicker('destroy');//强制赋值前需要做的
                $("#address-form").distpicker({
                  province: app.AdrList.province,
                  city: app.AdrList.city,
                  district: app.AdrList.district
                });

              } else {
                  layer.msg(res.data);
              }
              layer.close(loading);
          });
