问题 I have a code segment that looks like this: async function autoScroll(page, maxDate = null) { await page.evaluate(async () => { await new Promise(async (resolve, reject) => { try { const scrollHeight = document.body.scrollHeight; let lastScrollTop = 0; const interval = setInterval(async () => { window.scrollBy(0, scrollHeight); const scrollTop = document.documentElement.scrollTop; let lastDate = null; if (maxDate) { const html = new XMLSerializer().serializeToString(document.doctype) +

问题 I am a newbee to the express nodejs applications. I want to make a todo list. This is how it looks so far. My question is when I add a todo, it takes some time to show the change since it reloads the page. How can I see the change in realtime without reloading the page. Thanks in advance. in tasks.jade h1= title .list .item.add-task div.action form(action='/tasks', method='post', id='12345') input(type='hidden', value='true', name='all_done') input(type='hidden', value=locals._csrf, name='

问题 I've been searching around the internet and combining lots of different pieces of code, but I'm just not succeeding at creating a callback for my asynchronous job. The idea is that I want to run multiple jobs, and using the callback methods I will be able to parse the output from the different jobs to change certain states and output in the main script. Currently I have this, and although the event gets called, I'm unable to get the actual output. What am I missing here? $rsPool =

问题 I'm reallt trying to get my head around async/await and Tasks . I'm trying to get one method down so that I can use it throughout my program. Basically I have my own version of BusyIndicator that I want to display whilst work is being done. Here is a basic example; private async void OnPageLoad(object sender, RoutedEventArgs e) { var waitWindow = new PleaseWaitWindow(); waitWindow.Show(); await LoadCompanyContracts(); waitWindow.Close(); } private async Task LoadCompanyContracts() { await
