💡 需求背景和解决方案
Textarea 当前缺少与 Input 一致的可清空能力。本 PR 为 React Textarea 组件补充 clearable API、交互逻辑、示例和测试,使多行文本输入可以快捷清空。
实现内容:
clearableproponClear回调change,trigger 为clear交互行为对齐现有 Input clearable:仅在
clearable开启、存在输入内容、非 disabled、非 readonly 且鼠标悬浮时展示清除入口,并复用CloseCircleFilledIcon作为清除控件。当前 demo 聚焦展示 clearable 的主交互流程,因此只提供一个非 disabled、非 readonly 状态下的可输入 Textarea:输入区有默认内容,鼠标悬浮时展示清除图标,点击后清空内容并触发
clear回调。这样可以直接覆盖本次 issue 关注的“快捷清空输入内容”能力,也与现有 Input clearable demo 的单输入框展示方式保持一致。disabled、readonly、empty 等状态的行为已在组件逻辑和单元测试中覆盖。如果维护者希望在文档中补充多状态静态展示,可以后续继续追加对应 demo。
公共视觉样式由
tdesign-common提供,本仓库只负责组件交互逻辑、事件触发、demo 与测试。效果展示:
