如何通过自动更新实现天气预报?

请帮忙，目前我有一个错误'类型错误：天气.sys是未定义的。我使用开放天气图。我希望每个块根据城市自动更新日期、水和空气温度。我必须马上说，地理位置将集中在俄罗斯我会很高兴你的回答。

发生这种情况是因为您将整个标签作为城市名称而不是 innerHTML 传递：

getResults(city.innerHTML);

您收到天气.sys错误，因为天气变量不包含任何数据。因此，您应该在 displayResults 函数内或调用它之前添加一些错误处理。

编辑：添加了温度更新：

var parent = document.querySelector('.' + weather.name.toLowerCase()).parentNode
parent.querySelector('.weather__current-temp .weather__temperature').innerHTML = Math.round(weather.main.temp) + '<sup>o</sup>C - air';

这段代码非常丑陋，但它只是它应该如何工作的一个例子。您应该将温度 html 构建和父搜索移动到单独的函数中。如果您为所有weather__city元素提供城市类，这将起作用。

如果您不想添加城市类，并且想通过innerText搜索父级，请检查此答案：如何通过innerText获取元素

它的工作原理是这样的：

const api = {
	key: "11c85ec89d2ab590110511a07349dd25",
	baseurl: "https://api.openweathermap.org/data/2.5/"
}
const weather__wrapper = document.addEventListener('DOMContentLoaded', setQuery);
var check = document.querySelector('.weather__city').textContent;
function setQuery(evt) {
	const wrappers = document.querySelectorAll('.weather__wrapper');
	wrappers.forEach( w => {
	   var city = w.querySelector('.weather__city');
	   getResults(city.innerHTML);
	});
}
function getResults (query) {
	fetch(`${api.baseurl}weather?q=${query}&units=metric&APPID=${api.key}`)
	.then(weather=> {
		return weather.json();
	}).then(displayResults);
}
function displayResults(weather) {
	let city = document.querySelectorAll('.weather__text .weather__city');
	city.innerText = `${weather.name}, ${weather.sys.country}`;
	let now = new Date();
	let date = document.querySelector('.weather__text .weather__date');
	date.innerText = dateBuilder(now);
document.querySelector('.' + weather.name.toLowerCase()).parentNode.querySelector('.weather__current-temp .weather__temperature').innerHTML = Math.round(weather.main.temp) + '<sup>o</sup>C - air';
}
function dateBuilder(d) {
	let months = ["01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12"];
	let date = d.getDate();
	let month = months[d.getMonth()];
	let year = d.getFullYear();
	return `${date}.${month}.${year}`;
}
