问题 I am trying to print the current timestamp in a file using Timers in Nodejs. If I'm using setInterval , I am able to print the current timestamp in the output file, but the the value of it never changes... (it takes the first value of timestamp and then it just prints it every 1000ms....) This was the code: export class App { private getData() { return Date.now(); } private async printToFile(path: string, data: number) { try { fs.writeFile(path, data + '\n', { 'flag': 'a' }, function (err) {

问题 I've implemented a standard jQuery auto grow/expand textarea plugin into iPhone my web app . It's working fine except for two issues (listed below) .

问题 So I have very limited knowledge of javascript, so I apologize in advance for my stupidity. I am trying to make it so that these alerts play 16 seconds after the website is initially opened. In the background, there is a video playing and it seems like the video has an effect on the website, but in reality, it's just played in a particular way. How can I get it so that the three alerts play 16 seconds from the opening of the website? Where do you put the settimeout, or where in the code do

问题 I'm trying to make image rotator with Jquery, but my rotator won't stop when I put the mouse over the images, so I'm guessing that something's wrong with clearTimeout. Here's my code: $(document).ready(function () { var o = 0 var t = null; stop = false; $("img:gt(0)").hide(); broj = ($("img").size()); function promena() { o++; if (o == broj) { o = 0; $("img:lt(3)").hide(function () { $("img").eq(3).delay(1000).fadeOut(1000); }); } $("img").eq(o).delay(1000).fadeIn(1000, function () { t =

问题 I have the following function which runs OK except for one thing. There is no consequence in what it appends first. (function biograf(){ var placeholder = $('#top-imageholder'); $('ul#biomenu > li').each(function(){ var obj = $(this); var pageLink = obj.find('a:first').attr('href'); $.get(pageLink, function(data) { placeholder.append( $(data).find('#top-imageholder').html() ); placeholder.append( $(data).find('#top-imageholder').siblings('ul') ); }); }); })(); I would like the function to

问题 Im trying to simulate a Typewriter effect with javascript. Theorically it should work with my code: function TypeWriteToDoc(txt, id, x){ document.getElementById(id).innerHTML = document.getElementById(id).innerHTML + txt.charAt(x); } function TypeWrite(txt,id){ for (var i = 0; i < txt.length; i++){ setTimeout(function() { TypeWriteToDoc(txt, id, i); }, 1000*(i+1)); } } That should be it, when i call TypeWrite("example", "p_test"); it should write each character of "test" in the "p_test" html.
