### 使用
> 到 [GitHub](https://github.com/Rattenking/WXTUI-DEMO) 下载 WX-RUI 的代码，将 component 目录拷贝到自己的项目中。然后按照如下的方式使用组件，以 dtpicker 为例，其它组件在对应的文档页查看：
#### 1. 添加需要的组件。在页面的 json 中配置（路径根据自己项目位置配置）：
```
"usingComponents": {
"rui-dtpicker": "../../component/picker/picker"
}
```
#### 2. 在 wxml 中使用组件：
2.1 时间粒度为second的实例
```
<rui-dtpicker
start="2018-03-15 10:45:00"
end="2050-03-15 10:45:00"
value="{{value}}"
fields="second"
bindchangedatepicker="changeDate"
bindcanceldatepicker="cancelDate"
></rui-dtpicker>
```
2.2 时间粒度为year的实例
```
<rui-dtpicker
start="2018"
end="2050"
value="{{value}}"
fields="year"
bindchangedatepicker="changeDate"
bindcanceldatepicker="cancelDate"
></rui-dtpicker>
```
