## 使用示例
## dataList 为对象数组时,name为实际保存的value值,text为显示的值
## dataList 为对象数组[{name:'张三', age:'18'}, {name:'李四', age:'19'}]时,需要设置name、text属性,name为实际保存的value值,text为显示的值
## <hpy-form-select :dataList="dataList" text="name" name="age" v-model="formData.age" @change="change" />
## ======================================================================================================
## dataList 为普通数组['张三', '李四'] name、text可不设置
## <hpy-form-select :dataList="dataList" v-model="formData.name" @change="change" />
## 类似:
## <select><option value="name">text</option></select>
```html
<hpy-form-select :dataList="hobbyList" text="text" name="value" v-model="formData.hobbySelect" @change="change" />
<uni-group title="基础信息" margin-top="0">
<uni-forms-item label="姓名" name="name">
<uni-easyinput type="text" v-model="formData.name" placeholder="请输入姓名" />
</uni-forms-item>
<uni-forms-item label="爱好2" name="hobby2">
<hpy-form-select :dataList="hobbyList" text="text" name="value" v-model="formData.hobbySelect"/>
</uni-forms-item>
<uni-forms-item label="爱好3" name="hobby3">
<hpy-form-select :dataList="hobbyList" text="text" name="value" v-model="formData.hobbySelect3" islot="true">
<view class="my-select">可自定义显示</view>
</hpy-form-select>
</uni-forms-item>
<uni-forms-item label="出生时间(年)" name="birthYear" >
<hpy-form-select mode="date" fields="year" v-model="formData.birthYear" />
</uni-forms-item>
</uni-group>
```
```javascript
export default {

console.log(e.index);
console.log(e.value);
console.log(e.data);
