使用 JavaScript 刷新 DIV 失败
failed to refresh DIV with JavaScript
我想在 10 秒内自动刷新某些 DIV (darksky widget id="1")。
我试了很多次都失败了。请看下面并评论逻辑错误的地方。
这是我糟糕的代码。
function autoRefresh_sample_div2() {
var currentLocation2 = window.location;
$("#1").fadeOut('slow').load(currentLocation2 + ' #1').fadeIn("slow");
}
setInterval('autoRefresh_sample_div2()', 10000); //10 seconds

- 不建议使用数字 ID
- 您的负载没有从天气频道重新执行 iframe 脚本
所以我拿了天气 JS 看看它做了什么。
我将他们预期的 ID 添加到您的 div,然后使用随机值重新加载脚本以停止缓存,而不是加载整个页面并从中提取 div。
我尝试附加到头部的 "load" 事件以淡入,但我改用超时
const weather = new URL('https://darksky.net/widget/default-small/36.2385,127.2047/ca12/en.js?width=100%&height=70&title=Full Forecast&textColor=333333&bgColor=FFFFFF&transparency=false&skyColor=undefined&fontFamily=Default&customFont=&units=ca');
const reloadWeather = () => {
$('script[id="weather"]').remove();
weather.searchParams.set("rdn", new Date().getTime());
$('<script id="weather">').attr('src', weather).appendTo('head');

这对我们来说是个坏消息,因为他们使用 document.write。我想绕过它,但想出了一个更酷的解决方案:更新
时只需重命名每个 div
let tId, $divs, cnt = 0;
const reloadWeather = () => {
const $div = $(divs[cnt]);
$('script[id="weather"]').remove();
$("#customize-script-container").prop("id", "temp"); // rename the last div
$div.prop("id", "customize-script-container"); // set the ID expected of the script
const lat = $div.data("lat");
const long = $div.data("long");
let weather = new URL(`https://darksky.net/widget/default-small/${lat},${long}/ca12/en.js?width=100%&height=70&title=Full Forecast&textColor=333333&bgColor=FFFFFF&transparency=false&skyColor=undefined&fontFamily=Default&customFont=&units=ca`);
weather.searchParams.set("rdn", new Date().getTime());
$('<script id="weather">').attr('src', weather).appendTo('head');
setTimeout(() => {
$div.fadeTo("slow","1")
}, 1000);
};
$(function() {
divs = $(".weather");
tId = setInterval(() => {
if (cnt >= divs.length) cnt = 0;
const $div = $(divs[cnt]);
if ($div) {
$div.fadeTo("slow",0, function() {
reloadWeather();
cnt++;
})
} else {
console.log("div", cnt, "not found")
}
