3、address.json
/** * Created by kk on 2017/4/20. */ new Vue({ el:".container", data:{ limitNum:3, addressList:[] }, mounted:function () { this.$nextTick(function(){ // alter(); this.getAddressList(); }); }, computed:{ filterAddress:function () { return this.addressList.slice(0,this.limitNum); // 方法和属性需要加this，不然会找不到 } }, methods:{ getAddressList:function(){ var _this=this; this.$http.get("data/address.json").then(function(response){ var res=response.data; if(res.status=="0"){ _this.addressList=res.result; } }); } , loadMore:function () { this.limitNum=this.addressList.length; } } });
4、address.css
{ "status":"0", "message":"", "result":[ { "addressId":"100001", "userName":"JackBean", "streetName":"北京市朝阳区朝阳公园", "postCode":"100001", "tel":"12345678901", "isDefault":true }, { "addressId":"100002", "userName":"JackBean", "streetName":"北京市朝阳区朝阳公园", "postCode":"100001", "tel":"12345678901", "isDefault":false }, { "addressId":"100003", "userName":"JackBean", "streetName":"北京市朝阳区朝阳公园", "postCode":"100001", "tel":"12345678901", "isDefault":false }, { "addressId":"100004", "userName":"JackBean", "streetName":"北京市朝阳区朝阳公园", "postCode":"100001", "tel":"12345678901", "isDefault":false }, { "addressId":"100005", "userName":"JackBean", "streetName":"北京市朝阳区朝阳公园", "postCode":"100001", "tel":"12345678901", "isDefault":false } ] }
