是什么阻止了这个 function 执行其中的钩子？ 反应机制如何使这成为不可能？

Question

I'm trying to execute a function that executes other functions. The function itself executes but the functions inside of it do not. I thought I had a good grasp on React mechanics and it's lifecycle but I guess not. I do not understand why react is acting this way. Hoping for guidance/an explanation on the react component lifecycle and what about it that prevents this particular code from working.

Link directly to the function in question on CodeSandbox:

https://codesandbox.io/s/practical-gates-rr81j0?file=/src/hooks/getInfo.jsx:2112-2357

Context: I'm trying to make it so double clicking on the picture of the gun sets the camo boxes underneath it to "active". Each hook function for each box works individually, but when called together in a function nothing happens. Both console.log()'s execute, but not the functions in between them. I was under the impression that calling each "handle${Camo}Click" function in a separate function would work fine, but it doesn't. I don't know what to search to start figuring out the mechanics of why this happening. If anyone could point me in the right direction that would be very much appreciated.

Answer 1

Issue

The issue is that you've defined a useGetCompletionData hook with its own state, but use several instances of the hook so each instance has and maintains its own state independently.

The setAllCamos callback the the ASM10 image is calling is from a different instance of the useGetCompletionData hook that it's related CamoList component is using. In other words, when the image is double-clicked it's updating state the Camolist doesn't have access to.

Solution

I suggest creating a CompletionDataProvider component to wrap individual sets of images and CamoList components so they can share and reference the same state.

Example:

getInfo.jsx

import { createContext, useContext, useState } from "react";

export const CompletionData = createContext({
  goldIsActive: false,
  setGoldActive: () => {},
  totalCamo: 0,
  setTotalCamo: () => {},
  sandIsActive: false,
  handleSandClick: () => {},
  handleDragonClick: () => {},
  dragonIsActive: false,
  splinterIsActive: false,
  handleSplinterClick: () => {},
  tigerIsActive: false,
  handleTigerClick: () => {},
  handleReptileClick: () => {},
  reptileIsActive: false,
  jungleIsActive: false,
  handleJungleClick: () => {},
  setAllCamos: () => {},
});

const CompletionDataProvider = ({ children }) => {
  const [sandIsActive, setSandActive] = useState(false);
  const [dragonIsActive, setDragonActive] = useState(false);
  const [splinterIsActive, setSplinterActive] = useState(false);
  const [tigerIsActive, setTigerActive] = useState(false);
  const [reptileIsActive, setReptileActive] = useState(false);
  const [jungleIsActive, setJungleActive] = useState(false);
  const [totalCamo, setTotalCamo] = useState(0);
  const [goldIsActive, setGoldActive] = useState(false);

  const handleSandClick = () => {
    // 👇️ toggle isActive state on click
    setSandActive((current) => !current);
    if (sandIsActive) {
      setTotalCamo((prev) => prev - 1);
    } else {
      setTotalCamo((prev) => prev + 1);
    }
  };

  const handleDragonClick = () => {
    // 👇️ toggle isActive state on click
    setDragonActive((current) => !current);
    if (dragonIsActive) {
      setTotalCamo((prev) => prev - 1);
    } else {
      setTotalCamo((prev) => prev + 1);
    }
  };

  const handleSplinterClick = () => {
    // 👇️ toggle isActive state on click
    setSplinterActive((current) => !current);
    if (splinterIsActive) {
      setTotalCamo((prev) => prev - 1);
    } else {
      setTotalCamo((prev) => prev + 1);
    }
  };

  const handleTigerClick = () => {
    // 👇️ toggle isActive state on click
    setTigerActive((current) => !current);
    if (tigerIsActive) {
      setTotalCamo((prev) => prev - 1);
    } else {
      setTotalCamo((prev) => prev + 1);
    }
  };

  const handleReptileClick = () => {
    // 👇️ toggle isActive state on click
    setReptileActive((current) => !current);
    if (reptileIsActive) {
      setTotalCamo((prev) => prev - 1);
    } else {
      setTotalCamo((prev) => prev + 1);
    }
  };

  const handleJungleClick = () => {
    // 👇️ toggle isActive state on click
    setJungleActive((current) => !current);
    if (jungleIsActive) {
      setTotalCamo((prev) => prev - 1);
    } else {
      setTotalCamo((prev) => prev + 1);
    }
  };

  const setAllCamos = () => {
    handleSandClick();
    handleDragonClick();
    handleSplinterClick();
    handleTigerClick();
    handleJungleClick();
  };

  const value = {
    goldIsActive,
    setGoldActive,
    totalCamo,
    setTotalCamo,
    sandIsActive,
    handleSandClick,
    handleDragonClick,
    dragonIsActive,
    splinterIsActive,
    handleSplinterClick,
    tigerIsActive,
    handleTigerClick,
    handleReptileClick,
    reptileIsActive,
    jungleIsActive,
    handleJungleClick,
    setAllCamos
  };
