# Utils

> Util function services

!>In `weex-ui` V0.6.0 version above, in order to reduce packaging size, `Binding related judgments` are transferred from `Utils.env` to `BindEnv`.

## Code Example

```vue
<script>
  import { Utils } from 'weex-ui';
  // Utils.env.getPageHeight();
  // 如果想使用 bind 相关判断
  // import { BindEnv } from 'weex-ui';
</script>
```
