1、HarmonyOS grid里面的item支持拖动问题？
想要grid里面的item支持拖动,拖出来后可以删除,下面的代码就是你们上次给我提供的,正常情况下是可以使用的但是,往下拖的过程中遇到了TextInput后,gridItem的onDragMove就不会走了,我给TextInput设置了draggable(false)后无法解决
import { media } from '@kit.MediaKit';

2、HarmonyOS Webview的onErrorReceive里回调的错误码，和文档里对不上？
Webview的onErrorReceive里回调的错误码，和文档里对不上：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/errorcode-webview-V5
有的返回-2，有的返回-106，有的-302。
参考以下文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-neterrorlist-V5
3、HarmonyOS 如何通过context: common.Context获取页面的名称和唯一性？
- 在当前页面可以使用router.getstat来获取页面名称：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-router-V5
- 使用getStringValue获取标识：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-resource-manager-V5
4、HarmonyOS 咨询文本动效、点击从某个位置显示Text并向上Y移动一定距离后自动隐藏；并在连续快速点击时，多个Text显示并根据点击的间隔时间，依次向上位置一段距离并隐藏，实现类似弹幕效果？
Text组件文本动效、点击从某个位置显示Text并向上Y移动一定距离后自动隐藏；并在连续快速点击时，多个Text显示并根据点击的间隔时间，依次向上位置一段距离并隐藏，实现类似弹幕效果。
参考下面的方法：
- 创建Image组件点击时文本出现
- 文本用@buildPrams，每点击一次出现文字
- 文本特效可以借助transition实现
