ant is when I click the div(question) then the URL that is assigned to that question should load in the ReactPlayer..
This is how it looks so far:
import React, { useState } from "react";
import Ques tions from "../data/questions.json";
import style from "./Card.module.css";
import ReactPlayer from "react-player/youtube";
function Card() {
const handleClick = (item) => {
console.log(item);
};
return (
{ListQuestions.map((ListItem, index) => {
return (
handleClick(ListItem.url)} key={index} className={style.Card}>
...
< div class = "md_content_show e397 data - v - 3967" = "" >

这是我试图做的:当一个按钮被点击,一个段落元素被另一个段落元素取代。我希望它是无缝的,其中一个段落元素消失,而另一个段落元素出现在它的地方。但是无论我做什么尝试,我似乎都无法得到其他段落元素出现。要隐藏的段落元素很好地消失了,但另一个span元素没有在它的位置出现我尝试过很多不同的方法,比如text to show
...
document.getElementById('element _to_show').style.display = "block";
和text to show
...
document.getElementById('element_to_show').hidden = false;
和text to show
...
document.getElementById('element_to_show'). style.visibility = "visible";
但似乎什么都不起作用我知道,在Javascript中,我可以创建新的段落我想通过document.createElement(),然后使用replaceWith(),但有各种其他元素在段落元素,我将不得不重新创建,这将是混乱的编程。更不用说,当用户单击另一个按钮将该段落元素带回来时,我必须重新创建原始的段落元素。在HTML中编写元素代码...
我如何保存输出从终端在txt文件,也打印输出在终端在同一时间?I tried with python3 script_name>output. TXT ,但这将输出保存在TXT文件中,但终端中没有发生任何事情。我也有plt.show(),当脚本结束时,它需要显示输出图像,但说的错误:UserWarning: Named tensors and all their associated APIs a re an experimental feature and subject to change.

谢谢你的时间:这个想法是,Apple code -> ["APPLE"++show code]
Apples codes -> map (\x -> ["APPLE"++ show x]) codes
可以包含一个苹果的代码(以整数表示)苹果代码处理程序将分支的基础上输入如果是苹果则返回一个字符串如果是苹果,则返回一个字符串列表问题是,为什么Haskell编译器抱怨,它期望Apples codes -> map (\x -> ["APPLE"++ show x]) codes
Apple code -> ["APPLE"++show code]

当开始一个新项目时,OpenCV刚刚决定停止在我的PC和笔记本电脑上工作。我使用的是Python 3.9。像“imread”和“imshow”这样的基本命令不再有效。我已经卸载和重新安装了Python和Pycharm。我把模块拆了,重新安装了…然而,它仍然不能正常工作。这是我从未见过的错误。import cv2 as cv
img = "Nemo.jpg"
cv.imread(img)
cv.i mshow("feesh", img)
Traceback (most recent call last):
