Вопрос:
Привет 🙂 Я пытаюсь немного угадать игру с числами в JS, чтобы я мог, наконец, выучить этот язык, и, несмотря на то, что функциональность выполнена, у меня есть некоторые проблемы с добавлением кнопки, сгенерированной JS, в div контейнера вместо тела.
let randomNumber = Math.floor(Math.random() * 100) 1;
const guesses = document.querySelector(".guesses");
const lastResult = document.querySelector(".lastResult");
const lowOrHi = document.querySelector(".lowOrHi");
const guessField = document.querySelector(".guessField");
const guessSubmit = document.querySelector(".guessSubmit");
let guessCount = 1;
let resetButton;
guessField.focus();
function checkGuess() {
let userGuess = Number(guessField.value);
if (guessCount === 1) {
guesses.textContent = "Previous guesses: ";
}
guesses.textContent = userGuess " ";
function setGameOver() {
guessField.disabled = true;
guessSubmit.disabled = true;
resetButton = document.createElement('button');
resetButton.textContent = 'Start new game';
document.body.append(resetButton);
resetButton.addEventListener('click', resetGame);
}
function resetGame() {
guessCount = 1;
const resetParas = document.querySelectorAll('.resultParas p');
for (let i = 0; i < resetParas.length; i ) {
resetParas[i].textContent = '';
}
resetButton.parentNode.removeChild(resetButton);
guessField.disabled = false;
guessSubmit.disabled = false;
guessField.value = '';
guessField.focus();
lastResult.style.backgroundColor = 'white';
randomNumber = Math.floor(Math.random() * 100) 1;
}
if (userGuess === randomNumber) {
lastResult.textContent = "Congratulations! You got it right.";
lastResult.style.backgroundColor = "green";
lowOrHi.textContent = " ";
setGameOver();
} else if (guessCount === 10) {
lastResult.textContent = "Game over! No more turns!";
setGameOver();
} else {
lastResult.textContent = "Wrong";
lastResult.style.backgroundColor = "red";
if (userGuess < randomNumber) {
lowOrHi.textContent = "Your last guess was too low!";
} else if (userGuess > randomNumber) {
lowOrHi.textContent = "Your last guess was too high!";
}
}
guessCount ;
guessField.value = " ";
guessField.focus();
}
guessSubmit.addEventListener("click", checkGuess);

Мне бы очень хотелось, чтобы кнопка «Начать новую игру» находилась внутри div вместе с остальными элементами, чтобы я мог сделать ее более привлекательной.
Ответ №1:
Вы можете получить элемент, к которому вы хотели бы прикрепить кнопку, с помощью document.getElementsbyClassName
функции, а затем добавить к нему:
В следующем примере я присоединил элемент к form
классу div.
let randomNumber = Math.floor(Math.random() * 100) 1;
const guesses = document.querySelector(".guesses");
const lastResult = document.querySelector(".lastResult");
const lowOrHi = document.querySelector(".lowOrHi");
const guessField = document.querySelector(".guessField");
const guessSubmit = document.querySelector(".guessSubmit");
let guessCount = 1;
let resetButton;
guessField.focus();
function checkGuess() {
let userGuess = Number(guessField.value);
if (guessCount === 1) {
guesses.textContent = "Previous guesses: ";
}
guesses.textContent = userGuess " ";
function setGameOver() {
guessField.disabled = true;
guessSubmit.disabled = true;
resetButton = document.createElement('button');
resetButton.textContent = 'Start new game';
formElem = document.getElementsByClassName("form")[0]
formElem.append(resetButton);
resetButton.addEventListener('click', resetGame);
}
function resetGame() {
guessCount = 1;
const resetParas = document.querySelectorAll('.resultParas p');
for (let i = 0; i < resetParas.length; i ) {
resetParas[i].textContent = '';
}
resetButton.parentNode.removeChild(resetButton);
guessField.disabled = false;
guessSubmit.disabled = false;
guessField.value = '';
guessField.focus();
lastResult.style.backgroundColor = 'white';
randomNumber = Math.floor(Math.random() * 100) 1;
}
if (userGuess === randomNumber) {
lastResult.textContent = "Congratulations! You got it right.";
lastResult.style.backgroundColor = "green";
lowOrHi.textContent = " ";
setGameOver();
} else if (guessCount === 10) {
lastResult.textContent = "Game over! No more turns!";
setGameOver();
} else {
lastResult.textContent = "Wrong";
lastResult.style.backgroundColor = "red";
if (userGuess < randomNumber) {
lowOrHi.textContent = "Your last guess was too low!";
} else if (userGuess > randomNumber) {
lowOrHi.textContent = "Your last guess was too high!";
}
}
guessCount ;
guessField.value = " ";
guessField.focus();
}
guessSubmit.addEventListener("click", checkGuess);

Ответ №2:
Просто найдите свой родительский div:
const yourDiv = document.getElementById('yourDivId');
А затем добавить к нему кнопку:
yourDiv.appendChild(resetButton);
