我遇到了,这似乎是“相似”,以应对在反应的JSON对象等问题的问题,但我似乎无法如何将这些答案翻译。我创建一个小游戏内作出反应(没有反应过来母语)。我可以打电话给我的JSON对象和拉文本,但是,当涉及到拉的图像路径,也不会呈现。要获得这个游戏的基本概念(这是在HTML / JS)采取look at this link for the overall functionality。
这是问题,我有一个基于状态的父Component(GameLogic.js)对象的动态渲染集。我再穿过状态下至玄孙孙子元素,其中将呈现两张照片。这些照片路径存储在本地JSON文件(我可以阅读在这个级别从在的console.log的characters.json文件中的字符串)。虽然它可以读取路径(通过执行console.log),不渲染这些图像。我是怎么过能只要渲染这些图像,因为我不串在一起很长的动态路径。
下面是该文件的结构:
-components folder
|-GameLogic.js (parent element that handles the render)
|-Bandersnatch.js (child element)
|-NewComponents folder
|-ImageContainer.js (grandChild element)
|-ImageSquare.js (great grandChild element)
-images folder
|-snatch_images folder (yes... I know how bad this sounds...)
|-escape_snatch.png
|-The rest of the images (there are about 20)
-characters.json
-App.js
JSON例如:我需要在阵列的文件路径[0] .scene [0] .choiceOneImg
[
{
"name": "Giraffe",
"alive": true,
"active": true,
"staticImg": "images/characters/static/static_giraffe.png",
"animatedImg": "images/characters/animated/animated_giraffe.png",
"cagedImg": "images/characters/caged/caged_giraffe.png",
"scene": [
{
"used": false,
"backgroundImg": "images/BG_images/zooBG.png",
"question": "........." ,
"answerTrue": ".......",
"answerFalse": ".......",
"choiceOne": "RUN FOR IT!",
"choiceTwo": "Stay loyal",
"choiceOneImg": "../images/snatch_images/escape_snatch.png",
"choiceTwoImg": "images/snatch_images/stay_snatch.png",
"incorrectResult": 0,
"correctAnswer": "choiceOne",
"correct": true
},
下面是通过当前字符,从不断变化的状态,现场位置的父,GameLogic.is:
import React, { Component } from "react";
import Snatch from "./Bandersnatch";
import characters from "../characters.json";
class GameLogic extends Component {
state ={
unlockedCharacters : 0,
currentCharacter : 0,
sceneLocation : 0,
points : 0,
showCaracterSelect: true,
showMessage: false,
showSnatch: false,
showCanvas: false,
}
componentDidMount() {
}
render() {
return (
<Snatch
sceneLocation = {this.state.sceneLocation}
currentCharacter = {this.state.currentCharacter}
choiceOneAlt = "ChoiceOne"
choiceOneImg = {characters[this.state.currentCharacter].scene[this.state.sceneLocation].choiceOneImg}
choiceTwoAlt = "ChoiceTwo"
choiceTwoImg = {characters[this.state.currentCharacter].scene[this.state.sceneLocation].choiceTwoImg}
/>
)
}
}
export default GameLogic;
那么这个被传递到子组件,Bandersnatch.js:
import React, { Component } from "react";
import characters from "../characters.json";
import { HeaderH2, ImageContainer, ImageSquare, ImageText, ProgressBar, Timer } from "./NewComponents/AllComponents";
const Snatch = (props) => {
return (
<>
<title>Decision Time</title>
<div className="w3-container">
<div className="container">
<HeaderH2 text="What Would You Like To Do?" />
<div className="row">
<ImageContainer
sceneLocation = {props.sceneLocation}
currentCharacter = {props.currentCharacter}
choiceOneAlt = {props.choiceOneAlt}
choiceOneImg = {props.choiceOneImg}
choiceTwoAlt = {props.choiceTwoAlt}
choiceTwoImg = {props.choiceTwoImg}
/>
{/* <ProgressBar /> */}
{/* <ImageText
sceneLocation = {props.sceneLocation}
currentCharacter = {props.currentCharacter}
/> */}
</div>
</div>
</div>
</>
);
}
export default Snatch;
然后传递给ImageContainer:
import React, { Component } from "react";
import ImageSquare from "./ImageSquare";
import characterObject from "../../characters.json";
const ImageContainer = (props) => {
return (
<>
<div className="col-md-6 optionOneclassName">
<ImageSquare
imgsrc={props.choiceOneImg}
altText={props.choiceOneAlt}
/>
</div>
<div className="col-md-6 optionTwoclassName">
<ImageSquare
imgsrc={props.choiceTwoImg}
altText={props.choiceTwoAlt}
/>
</div>
</>
)
};
export default ImageContainer;
然后终于接受在ImageSquare.js:
import React from "react";
const ImageSquare = (props) => { // passing in the img src
return (
<img src={props.imgsrc} alt={props.altText} height="600" width="600" />
)
};
export default ImageSquare;
非常感谢你的帮助!我不知道这是否是更容易,but the repo is here
使用需要加载图像。传递路径IMG直接将无法正常工作。要么你需要输入或需要加载图像
你需要的路径前添加../
更改
import React from "react";
const ImageSquare = (props) => { // passing in the img src
return (
<img src={props.imgsrc} alt={props.altText} height="600" width="600" />
)
};
export default ImageSquare;
至
import React from "react";
const ImageSquare = (props) => { // passing in the img src
const path = "../"+props.imgsrc;
return (
<img src={require(path)} alt={props.altText} height="600" width="600" />
)
};
export default ImageSquare;
