Input ​

Text-input foundation for controlled values, formatting, readonly, invalid state, length, and textarea autosize.

Runtime ownership ​

useFieldRoot comes from @varo-ui/headless; IME, DOM/WXML, and autosize stay target-owned.

Demo ​

Package@varo-ui/headless

Install ​

bash
pnpm add @varo-ui/headless @varo-ui/h5
# or
pnpm add @varo-ui/headless @varo-ui/weapp

Why this is foundational ​

  • Every form field needs one value and invalid contract.
  • Business wrappers can reuse formatter timing without replacing the primitive.

Parts ​

PartRole
InputRootValue, state, formatting, and native input events

State and events ​

  • State：value, defaultValue, disabled, readonly, and invalid
  • Events：update:value, valueChange, focus, and blur.

Platform notes ​

H5 supports textarea autosize; Weapp preserves the public contract on native inputs.
