VUE开发小应用：查看各地区天气预报。废话不多说，直接上代码：

<div><img src="img/logo.png" alt="logo" /></div>
<div>
<input

<button @click="searchWeather">搜 索</button>

<div>

<ul v-cloak="block">

</div>
<div>
<b>{{item.low}}</b>

</div>
<div><span>{{item.date}}</span></div>

</ul>
</div>
<!-- 开发环境版本，包含了有帮助的命令行警告 -->
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<!-- 官网提供的 axios 在线地址 -->
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
<!-- 自己的js -->
<script src="./js/main.js"></script>
</body>
</html>
至于样式CSS，这里就不想多说，大家自己去布局咯，只是分享下main.js代码：
/*
请求地址:http://wthrcdn.etouch.cn/weather_mini
请求方法:get
请求参数:city(城市名)
响应内容:天气信息
1. 点击回车
2. 查询数据
3. 渲染数据
*/
var app = new Vue({
el: "#app",
data: {
city: '',
weatherList: []
},
methods: {
searchWeather() {
if (this.city == '') {
alert("请输入城市！");
} else {
var that = this;
axios.get('http://wthrcdn.etouch.cn/weather_mini?city=' + that.city).then(function (response) {
if (response.data.status == 1002) {
alert("您输入的城市有误！请重新输入！");
that.city = '';
} else {
that.weatherList = response.data.data.forecast;
console.log(response.data);
}
}).catch(function (error) {
console.log(error);
})
}
},
searchWeatherByCity(city) {
this.city = city;
this.searchWeather();
}
},
})
大家可以去试试吧。
