var app = new Vue({
el:"#app",
data:{
city:'',
weatherList:[]
},
methods: {
searchWeather:function(){
// console.log('天气查询');
// console.log(this.city);
// 调用接口
// 保存this
var that = this;
axios.get('http://wthrcdn.etouch.cn/weather_mini?city='+this.city)

console.log(response.data.data.forecast);
that.weatherList = response.data.data.forecast
})
.catch(function(err){})
