hotkeys-react

说明

本仓库由https://github.com/jaywcjlove/react-hotkeys改进而来，因为原来仓库在react19.0会存在类型问题。由此我想重新改写一遍。

React component to listen to keydown and keyup keyboard events, defining and dispatching keyboard shortcuts. Uses a fork of hotkeys.js for keydown detection of special characters. You give it a keymap of shortcuts & it bind it to the mousetrap singleton. The, it'll unbind it when the component unmounts.

Example

Install

npm i -S hotkey-react

  const handleKeyUp = (keyName, e, handle) {
    console.log("test:onKeyUp", e, handle)
    setOutput(`onKeyUp ${keyName}`)
  }
  const handleKeyDown(keyName, e, handle) {
    console.log("test:onKeyDown", keyName, e, handle)
    setOutput(`onKeyDown ${keyName}`)
  }

  return (
      <Hotkeys
