JavaScript - How To Display 'loading Pls Wait Message' Using Javascript

Hi,

I am a newbie in JS, and have already been stuck with this problem for
the whole day.

Basically I want to display a var returned from a function with
<fmt:message/> tag. It sounds easy, but somehow I just can't get it
to be display correctly (Tried with alert() and it worked). Here is
my code:

-------------------------------------------------------------------------------------------
<script>
function ReturnTime() {
var dateobj=new Date();
if (dateobj.getSeconds()%30==0) {
return dateobj.getSeconds();
}
else {
return dateobj.getSeconds();
}
}

time1 = ShowTime();

alert(time1);

</script>

<fmt:message key='content.currentTime'/>: <cut value="${time1}"/>

-------------------------------------------------------------------------------------------------------------------------

I might have done some stupid things here. But I am very new to JS (2
days of experience so far). So please be patient.

Your kind help will be very much appreciated.

Regards,

Robert

Hi guys im trying to give users a warning message with javascript when the submit my login form without inserting any new data.
But I can't seem to find out how to stop the form from going to the login.php

here is my code.

Code:

<form name="te" onsubmit='login();' action='login.php' method='post'>
         <input name='username' maxlength='14' value='Username' type='text' />
          <input name='password' maxlength='20' value='Password' type='password' />
          <input type="submit" name="login" value="Login" />
</form>

javascript:
Code:

<script type="text/javascript">
function login() {
	var username = document.te.username.value;
	var password = document.te.password.value;
	
	if (username == 'Username' || username == '') {
		alert('empty username!');
		return false;
	}
	else {
		if (password == 'Password' || password == '') {
                                       alert('empty pass');
                                       return false;
		}
	}
             return true;
}
</script>

Hello. I've recently implemented this really cool jQuery preloader called queryLoader. When a visitor comes to my site they are fed all the important images for the entire site (it's a very small site). During that time queryLoader shows a percentage loading animation, and once all the images are loaded it wipes the screen & displays the website.

I've placed another custom animation in the "page loading" div, and i want to make sure it loads first so that it is displayed while the rest of the images get downloaded. I've tried pre-loading with javascript as the very first script in my header, before jQuery or queryLoader get loaded, like this:

Code:

<script type="text/javascript">
     pic1= new Image(250,300); 
     pic1.src="images/page_loading.gif"; 
</script>
<script type="text/javascript" src="scripts/jQuery.js"></script>
<script type="text/javascript" src="scripts/queryLoader.js"></script>

However, this doesn't seem to be that effective. When i clear browser cache and reload the page, the page_loading.gif sometimes doesn't appear until the site is almost completely loaded. Is there a more effective way to assure the page_loading.gif gets loaded before any other images?

My site is jugtones.com if that helps in any way. Thanks for your time, -Scott

Firebug is giving me no error messages, but alert() message is never triggered. I want the alert() message defined below to alert what the value of the variable result is (e.g. {filter: Germany}). And it doesn't. I think the javascript breaks down right when a new Form instance is instantiated because I tried putting an alert in the Form variable and it was never triggered. Note that everything that pertains to this issue occurs when form.calculation() is called:

markup:

Code:

        <fieldset> 
        <select name="filter" alter-data="dropFilter"> 
            <option>Germany</option> 
            <option>Ukraine</option> 
            <option>Estonia</option> 
        </select>    
        <input type="text" alter-data="searchFilter" /> 
    </fieldset>

javascript (below the body tag)
Code:

<script> 
(function($){ 
 
var listview = $('#listview'); 
 
var lists = (function(){ 
    var criteria = { 
        dropFilter: { 
            insert: function(value){ 
                if(value) 
                    return handleFilter("filter", value);   
            }, 
            msg: "Filtering..." 
        }, 
        searchFilter: { 
            insert: function(value){ 
                if(value) 
                    return handleFilter("search", value); 
            }, 
            msg: "Searching..."

Hi guys,

I am new here and am looking for a bit of help! I am building a website for a friend and am using Javascript. When I preview the site from my computer in Chrome/Firefox then all the JS elements render correctly.

I am using jCarouselLite by the way and have used HTML Boilerplate too.

However, when I upload the site the Carousel does not work...

Also, I seem to have a lot of scripts kicking around inside the html so I will give you a list of those, but here are my external JS files so my question before posting up all the code are 1.) what is the problem with rendering the JS elements live on t'internet, and 2.) can I reduce the amount of JS files/scripts to help page loading times?
css_browser_select.js modernizr-1.7.min.js jquery-1.6.1.min.js jcarousellite.js functions.js Code:

$(document).ready(function(){
	// Activate the main slider	
	$("#mainSlider").jcarousellite({
		btnNext: "#sliderBtnNext",
		btnPrev: "#sliderBtnPrev",
		visible: 1
	});
});

plugins.js script.js jquery.placeholder.min.js
and this is the code inside my HTML:

Head:

Code:

    <!-- CSS: implied media="all" -->

Hi, im having a problem adding a frame busting killer that counteracts a frame killer script on sites so i can load them inside my iframes..

here is the code i use

<?php
$result = mysql_query("SELECT ru.id, ru.username, ru.owid FROM raidbar_users ru LEFT JOIN raidbar_groups rg ON ru.groupid = rg.id WHERE rg.id = '".(int)$_REQUEST['group']."'") or die(mysql_error());
$myRaidid = raidid();

if(isset($_GET['gm']))

Now im told to use the following..
<script type="text/javascript">
var prevent_bust = 0
window.onbeforeunload = function() { prevent_bust++ }
setInterval(function() {
if (prevent_bust > 0) {
prevent_bust -= 2
window.top.location = 'http://server-which-responds-with-204.com'
}
}, 1)
</script>

or
var prevent_bust = 0;

// Event handler to catch execution of the busting script.
window.onbeforeunload = function() { prevent_bust++ };

// Continuously monitor whether busting script has fired.
setInterval(function() {
if (prevent_bust > 0) { // Yes: it has fired.
prevent_bust -= 2; // Avoid further action.
// Get a 'No Content' status which keeps us on the same page.
window.top.location = 'http://server-which-responds-with-204.com';
}
}, 1);


But the window.top.location i dont know how to incorporate that to work.

Can anyone help?

I know this was here previously but no solution was found and I wonder if someone could help.

JavaScript loads before even DOM is fully loaded but only in Chrome browser.

I know I could use setTimeout function but it's now ideal in my case.

I am working on a program based on Chromium and have a html page inside it. Page has 4 images that resize (useing javascript) depending on window size

Here is load finction
Code:

window.onload = function(){
			window.document.body.onload = initDocument;
		};
		
		function initDocument()
		{
			stretchFit("divMy", "bg");
			stretchFit("divG", "bgG");
			stretchFit("divTech", "bgTech");
			stretchFit("divKB", "bgKB");
		}

Any ideas how to load function after DOM is loaded?

I have a form that used php to load a random image but now i would like to use javascript instead and am sure I nearly have it. I need to have a random number between 0 -5.
Here is my code
Code:

<script type='text/javascript'>
var random = Math.floor( Math.rand() * 6);
document.write("<img src='images/'"+random+"'.jpg' alt='random image' /><input name='image' type='hidden' value='"+random+"' />")
</script>

Hi,

I'm currently working on my portfolio website and would like to have information about my movie clips be retrieved from an XML document when a thumbnail is clicked. I am building my website in HTML and would like to retrieve the Xml using JavaScript. Any help would be appreciated.

My XML is valid and structured as such:


<?xml version="1.0" encoding="UTF-8"?>
<work>

<motion>

<reel>
<title id="Demo Reel 2009" project="Self Promotion" client="Self">
<![CDATA[This demo reel is primaraly a collection ......]]>
</title>
</reel>
.
.
.
.


These are my initial variable definitions and readXML function in javascript:


<script language="javascript">

var xmldom, workNode, motionNode, printNode, fineartNode, displayNode, titleNode;


function readXMLDocument()
{

xmldom=createDocument();
xmldom.async=false;


if (xmldom.parseError != 0) {
alert("An error occurred: \nError Code " + xmldom.parseError.errorCode + "\n" + "Line: " + xmldom.parseError.line + "\n" + "Line Pos: " + xmldom.parseError.linepos + "\n" + "Reason: " + xmldom.parseError.reason);
} else {
alert("Document: " + xmldom.documentElement);
alert("Root: " + xmldom.documentElement.tagName);
alert("Child: " + xmldom.documentElement.firstChild.tagName);
alert("Xml DOM: " + xmldom.xml);
}


xmldom.load("workinfo.xml");


workNode=xmldom.documentElement;

motionNode=workNode.firstChild;

printNode=motionNode.nextSibling;

fineartNode=printNode.nextSibling;
}
.
.
.
.



A call to function revealText is called "onClick" of a thumbnail as such:


<a href="videopages/reel.html" class="vid" target="video" onClick="revealText(0)">


This is function revealText:


function revealText(x)
{
var title, project, client, info;

readXMLDocument();

displayNode=motionNode.childNode[x];


titleNode=displayNode.firstChild;


title=titleNode.getAttribute("id");
project=titleNode.getAttribute("project");
client=titleNode.getAttribute("client");
info=titleNode.getNodeValue();

titleSpan.innerHTML=title;
projectSpan.innerHTML=project;
clientSpan.innerHTML=client;
infoSpan.innerHTML=info;
}
</script>

and these are the spans they are written to:


<span id="titleSpan" class="vidinfo">

<span id="projectSpan" class="vidinfo">

<span id="clientSpan" class="vidinfo">

<p id="infoSpan" class="content">


If you have read this far, I REALLLLY appreciate it. And any ideas as to what is wrong would help alot.

Hello everyone,

I am just beginning to learn javascript, and I am trying to create a little game where when a user hovers over a picture it changes, and things like that.

At the moment I have been trying to make it so that the pictures tile so they fill the whole page area, dynamically so that it changes depending on the users browser size (px). The images have many attributes so I can't just tile them with css as they need to be actual elements.

The problem is the code doesn't run, and I can't work out why. I think all the lines that require it have semi colons and its all correct.

Forgive me if the answer is clear but as I said I only just started learning.

Anyway, on with the code:
Code:

<!doctype html>
<html lang="en">
<head>
<title>Hi, I'm a button.</title>
<link rel="stylesheet" type="text/css" href="style.css">
<script type="javascript">
