Fade in images after they have loaded

巧了我就是萌 提交于 2019-11-28 17:07:00
I found this code to achieve the desired effect and tried it on JSFiddle http://jsfiddle.net/AndyMP/7F9tY/366/ It seems to work in that it fades the image in after it has loaded. Then I tried it in a webpage and it didn't work the same way, loading the image first rather than fading it in. Although sometimes it seemed like it was fading in at the same time as it loaded. Is there a more reliable way of achieving this, preferably by amending this code if possible? $("#image").ready(function(){ $("#preload").fadeIn(1000); }); jfriend00 The only reliable way to fadeIn() an image that is in your

Understanding load average vs. cpu usage [closed]

南笙酒味 提交于 2019-11-28 15:48:53
Okay, I'm very much a Windows user myself, so my knowledge of Linux-y type things is a bit limited. However it was my general understanding that "Load Average" is an indication of how many processed are being run at any given time, on average over the last minute, five minutes and... fifteen minutes? Anyway, I've been monitoring my server because we had a big opening and lots of people! I've been watching top and noticed something that seemed contrary to what I thought I knew. If the load average is at 7, with 4 hyper-threaded processors, shouldn't that means that the CPU is working to about 7

jQuery .load() not working

孤者浪人 提交于 2019-11-28 13:24:11
On my website, I'm trying to pull the content of a post in my forum (hosted on the same domain) and display it in a div on the homepage, using jQuery. Here's the code for the header: <script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"> <script type="text/javascript"> jQuery("#contain").load("http://examplepage.com/forum/showthread.php?tid=NN #pid_NN"); </script> Then, there's the div I'd like to display the post: <div id="contain"></div> Things to consider: The library loads just fine. If I enter any other code, it works (like testing alert(1);). The

Do zombies exist … in .NET?

送分小仙女□ 提交于 2019-11-28 13:07:49
问题 I was having a discussion with a teammate about locking in .NET. He's a really bright guy with an extensive background in both lower-level and higher-level programming, but his experience with lower level programming far exceeds mine. Anyway, He argued that .NET locking should be avoided on critical systems expected to be under heavy-load if at all possible in order to avoid the admittedly small possibility of a "zombie thread" crashing a system. I routinely use locking and I didn't know what

Saving content of Interactive JTable to .txt file to read it upon next run

雨燕双飞 提交于 2019-11-28 13:00:22
问题 Hey guys I am currently writing a program that displays a JTable to the user, so they can input some data into the table window. Problem is, I can't figure out how to save any data, so the data can be re-opened when the app is run again. I would prefer the data to be saved automatically when the app is closed, but I'm happy to use a button if I need to. 回答1: I can't figure out how to save any data, From the JTable API (and all Swing components) you will see: Warning: Serialized objects of

谁都会走 提交于 2019-11-28 12:40:18
How do i load multiple html files and putting them into a specified html element? I tried with no changes: $('#asd').load('file.html,pippo.html'); you could get multiple items and add them to the element. jQuery.ajaxSetup({ async: false }); //if order matters $.get("file.htm", '', function (data) { $("#result").append(data); }); $.get("pippo.htm", '', function (data) { $("#result").append(data); }); jQuery.ajaxSetup({ async: true }); //if order matters Try this, using deferred objects. var defArr = []; defArr.push($.get('file.html')); defArr.push($.get('pippo.html')); $.when.apply($,defArr)

jQuery - Wait till background images have loaded then show element

♀尐吖头ヾ 提交于 2019-11-28 12:35:57
I did find a few places where it was told how to do this but it was either super inconvenient or just didnt work.. ( the guys own example did not work.. ) Basically i have background images that i would like to show at the same time instead of letting them to load in to the document when ever they please... I dont necessarily need them to be loaded first or anything but to wait until specific background images load up and then show their parent div.. Also if its possible.. it would make big difference if those background images could be defined to be loaded through classes rather than

问题 This is LC3 Assembly code I am working with .ORIG x3000 LOOP LDI R0, KBSR BRzp LOOP From LC3 Assembly, I know that LDI is a load indirect addressing mode, meaning it read in an address stored at an location and then read the value at that location From Lc3 Keyboard, I know that KBSR is the keyboard status register, which is one when keyboard has received a new character. Here is my test run in Lc3 simulator? I entered the character 'a' After executing LDI R0, KBSR, register 0 stores a value
