taro-hooks/es/useFrom/index.js

为 Taro 而设计的 Hooks Library

import { useRef } from '@taro-hooks/core';
import usePage from '../usePage';
function useFrom() {
  var _usePage = usePage(),
    stackLength = _usePage[0],
    pageStack = _usePage[1].pageStack;
  var generateFromInfo = function generateFromInfo() {
    return stackLength > 1 ? pageStack[stackLength - 2] : null;
  };
  return useRef(generateFromInfo()).current;
}
export default useFrom;
