Running JavaScript function before page load (setting background of appropriate size)

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-31 22:35:27
问题 I've got an image background which content I want to be always visible, no matter what is the user's resolution. Therefore, I want to be able to determine what is the resolution and set appropriate background image file before page loads, on the very beginning. Is it possible somehow? 回答1: The earliest point at which you can run a Javascript function with access to the DOM (without waiting for page load) is by placing a <script> tag right after the opening <body> tag. Scripts inside the <head

问题 Let's take a really simple example on using jQuery to ajaxify our page... $.load("getOrders.aspx", {limit: 25}, function(data) { // info as JSON is available in the data variable }); and in the ASP.NET ( HTML part ) page (only one line) <%@ Page Language="C#" AutoEventWireup="true" CodeFile="getOrders.aspx.cs" Inherits="getOrders" %> and in the ASP.NET ( Code Behind ) page public partial class getOrders : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { string lmt =

How were the weightings in the linux load computation chosen?

由 柔情痞子 提交于 2019-12-31 11:08:09
问题 In Linux, the load average is said to be on 1min/5min/15min. The formula used by the kernel is actually an Exponential moving average. If we define cpuload(1) as the first computation of the cpu load 1min, and active() as the function returning the number of process in state "running" or "runnable" on the system, then the formula used by the kernel to compute the nth cpu load 1min is: cpuload(0) is 0; it is the value stored in memory before the first execution of cpuload() . My question is,

问题 I am having trouble with IE 10 and jQuery .load(). I have a PHP page that I load once the website proper has loaded: $(document).ready( function() { $('#words').html('<div id="loading"><div id="loading-text">Analyzing frequency data...</div><div id="loading-image"><img src="loading.gif"></div></div>'); $('#words').load('translate.php?character=<?php echo $character1;?>'); }); It works fine in Chrome, but in IE the "loading" text appears for about 1 second and disappears, and the translate.php

How to load page synchronously using jQuery

由 余生长醉 提交于 2019-12-31 02:43:27
问题 Currently I am using jQuery to choose what my index page should load depending whether a cookie is set. For example, the body tag of the index.html should load hasCookie.html if the cookie is set and noCookieSet.html if no cookie is set. My index page currently has: load user scripts load styling scripts <html><body></body></html> The user script has the code that checks whether the cookie is set. If it is, I use jQuery's load to load the content into the body: $(document.body).load(

Loading Java JTable: Why does it not work?

由 删除回忆录丶 提交于 2019-12-31 02:01:05
问题 I have created a simple GUI which includes a JTable. This table may be saved & loaded via the appropriate Object Stream. At this point the Save function is working as intended, and I can see the table object is stored in a file when looking in the save directory. However, when I try to load the table from the file, the GUI never displays the loaded table. The actionlistener function is called, as I have a system.out "Data loaded", but the table never displays updated data. I have tried to

Memory Continues to Increase when Loading and Releasing NSImage

由 别说谁变了你拦得住时间么 提交于 2019-12-30 11:22:16
问题 I have a problem where my application aggressively consumes memory to a "thrashing point" with successive image file loads. For example, consider the following code, which repeatedly loads and releases a 15MB JPEG file (large file size for test purposes): NSURL *inputUrl = [NSURL URLWithString:@"file:///Users/me/Desktop/15MBjpeg.jpg"]; for(int i=0; i<1000; i++) { NSImage *image = [[NSImage alloc] initWithContentsOfURL:inputUrl]; [image release]; } It performs quickly for the first several

jQuery: Dynamic image handling (waiting for load)

由 倖福魔咒の 提交于 2019-12-30 07:19:08
问题 I'm trying to write a plugin that has a built in function to wait until all images that are on the page to be loaded before it executes itself. $(window).load() only works if it's the initial load of the page, but if someone wants to pull down some HTML through AJAX that contains images, it doesn't work. Is there any good way of doing this AND implementing it so that it can be self-contained in the plug-in? I've tried looping over $('img').complete , and I know that doesn't work (the images

How to know if all elements in a DIV have been fully loaded?

由 谁说我不能喝 提交于 2019-12-30 01:26:08
问题 There is a div in which there will be some elements (images, iframe, etc) being loaded via Ajax. After those elements have been fully loaded, I need to execute a function for the div . How do I determine if all elements in the div have been fully loaded? I use jQuery as the library. 回答1: For images and iframes you can use load event: // get all images and iframes var $elems = $('#div').find('img, iframe'); // count them var elemsCount = $elems.length; // the loaded elements flag var
