jQuery: Fire mousemove events less often

由 给你一囗甜甜゛ 提交于 2019-12-20 15:23:25
问题 I'm trying to figure out a clean way to aggregate mousemove events so that I ensure my code gets called, but only once every 250-300 milliseconds. I've thought about using something like the following, but was wondering if there was a better pattern, or something jQuery provides that will do the same thing: var mousemove_timeout = null; $('body').mousemove(function() { if (mousemove_timeout == null) { mousemove_timeout = window.setTimeout(myFunction, 250); } }); function myFunction() { /* *

Prevent Socket IO from ping timeout on inactive or not focused browser page on Chrome, firefox & Safari mobile browsers

由 怎甘沉沦 提交于 2019-12-20 06:47:15
问题 I have a simple chat app using socket io. Very similar to the socket io chat official demo. Socket io goes to ping timeout on all mobile browsers whenever the user minimizes the page or opens another app or page gets out of foucs. In my web app whenever, the user clicks on file input upload from their chrome/firefox/safari browser on mobile, it opens up the phone dialog box to select the file from galley to select and upload. During this time (my chat page gets out of focus due to visibility)

JavaScript: setTimeout doesn't pause the loop

由 我只是一个虾纸丫 提交于 2019-12-20 05:22:07
问题 I need to make some delays in my loop, every time after some amount of data (after a few cycles/iterations through my loop) is sent to the server. Sending data and receiving respond from the server works fine, but requested delays in loop still don't work. Thanks a lot for your help. EDIT: Code was changed, please check the third answer (mine). <!DOCTYPE html> <html> <body> <h2>AJAX</h2> <button type="button" onclick="loadDoc()">Request data</button> <p id="demo"></p> <script> function

Firefox setTimeout(func, ms) sending default parameters to callback

由 我与影子孤独终老i 提交于 2019-12-20 03:43:21
问题 I am unable to find out more about this default parameter that I ran across and was hoping that someone could point out an explanation. In Firefox (3.6 in this case) if you call the following code: function test(someVar) { console.log('test ' + someVar); } setTimeout(test, 0); It will log a "random" number to the console. I know you can pass parameters in Firefox like so: setTimeout(test, 0, param1, param2); But it appears as though Firefox is automatically sending a value. I think it's the

Question about setTimeout that I need answer to

由 最后都变了- 提交于 2019-12-20 02:06:13
问题 So we all know setTimeout waits a certain amount of time before executing something. My question is, does it wait for the above code to finish executing first, before waiting a second to execute something else, or does it just wait for a second, and whether or not the above code has finished executing, it executes the rest of the code anyways? if (1 == 1) { //huge chunk of code } //end of if (1 == 1) var theTime = 1000; var timeout = setTimeout("location.reload(true);", theTime); function

How to pass parameters to setTimeout function

问题 I am relatively novice to javascript. I have written a simple counter program that starts count down from 10 till it reaches 1. <script type="text/javascript"> function countDown(secs) { var element = document.getElementById("status"); element.innerHTML = "Please wait for "+secs+" seconds"; if(secs < 1) { clearTimeout(timer); element.innerHTML = '<h2>Countdown Complete!</h2>'; element.innerHTML += '<a href="#">Click here now</a>'; } secs--; ---> **var timer = setTimeout('countDown('secs')'
