vue2’s js syntax is posted for easy reference

1. Call the backend method

var _this = this; this.$http.get("data/address.json").then(function(response){ _this.addressList = response; //这里不能直接用this 此this非彼this 所以只能声明_this }); //以下为ES6写法，就可以直接用this了 let _this = this; //没用，就放这看看~ this.$http.get("data/cartData.json",{"id":123}).then(res=>{ this.productList = res.data.result.list; });

forEachLoop

this.productList.forEach(function(item,index){ if(typeof item.checked == 'undefined'){ //如果item中没有checked属性 在item对象中添加checked属性，值为true _this.$set(item,"checked",true);//局部注册 Vue.set(item,"checked",true);//全局注册 } });
