vue城市选择组件(按城市首字母排序)
- 我出生了
示例(vue@1.0+) 点我.
基于 vue.js@1.0+ 版本,模块使用es6编写(需babel转译),css使用scss编译(需scss-loader转译)。
当然你可以使用自己的数据,格式与此相符即可
$ npm install vue-city-picker china-city-data
参考示例,城市列表需要按指定的格式,并声明全局变量。
名称 | 类型 | 默认 | 说明 |
---|---|---|---|
value | String | "" | 要双向绑定的城市Id |
field | String | "" | 会给input标签添加name及id属性 |
placeholder | String | "" | 你懂的 |
no-hot | Boolean | false | 没有‘热门城市’ |
city-list | Object | window.CITY_PICKER_LIST | 可以自定义城市列表 |
<div id="app">
<label for="city">出发城市</label>
<city-picker field="city" placeholder="选择您的出发城市" :city-list="cityList" :no-hot="true" :value.sync="cityId"></city-picker>
</div>
<script>
import 'babel-polyfill'; //因为使用了es6的一些方法,需要babel垫片,如果你项目中已有相关兼容性方案,可忽略
import cityList from 'china-city-data';
import Vue from 'vue';
import myCityPicker from 'vue-city-picker';
//默认值,可以注册一个城市列表全局变量(考虑到cityList会比较大,如项目中多次使用,单独为一个js文件比较好)
window.CITY_PICKER_LIST = cityList;
new Vue({
el: '#app',
data: {
cityId: '',
cityList
},
components: {
'city-picker': myCityPicker
}
});
</script>
