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.

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.
