How cn I get it in pyramid form ? Thanks Similar TutorialsHello. Recently my company's site has been acting funny. Images on the page bladv.com/work aren't displaying except in older/non-updated browsers. When I ran Firebug to check the javascript, I got the following message twice. "NetworkError: 404 Not Found - http://bladv.com/assets/_cache/00000000009939b9184d06e0feb33450dc78b54e11.js" Does anyone know why I'm getting this code, and would this be the reason images on the page bladv.com/work aren't showing up? If this is the problem, how do I fix it? I tried adding the js file into the cache folder but I'm still getting the error codes in Firebug and the images are still invisible. Hope that makes sense, I'm very very new to javascript.

Thanks I am trying to debug this with FireBug Code: function chapter12_nodeOne() {
//create an element
var element = document.createElement('input');
//set some attributes
element.setAttribute('type', 'button');
element.setAttribute('value', 'submit');
//appendd the element into a DIV
document.getElementById('myDiv').appendChild(element);
//uses EventUtil to attach an event listener
(1) EventUtil.addHandler(element, 'click', function() { alert('added event handler') });
}
var EventUtil = {
(2)addHandler: function(element, type, handler) {
//check if the element and the browser support DOM Level 2 event attachment
//if the user is not browsing with IE
if (element.addEventListener) {
element.addEventListener(type, handler, false);
}
//if user is browsing with IE
else if (element.attachEvent) {
element.attachEvent("on" + type, handler);
}
//if user is using a browser that only supports DOM Level 0 event attachment
else {
element["on" + type] = handler;
}
},
removeHandler: function(element, type, handler) {
//check if the element and the browser support DOM Level 2 event attachment
//if the user is not browsing with IE
if (element.removeEventListener) {
element.removeEventListener(type, handler, false);
}
//if user is browsing with IE
else if (element.detachEvent) {
element.detachEvent("on" + type, handler);
}
//if user is using a browser that only supports DOM Level 0 event attachment
else {
element["on" + type] = null;
}
},
preventDefault: function(event)
{
if(event.preventDefault)
{
event.preventDefault();
}
else
{
event.returnValue = false;
}
}
};
I put a breakpoint on the line marked with (1), I am trying to go to line (2) with all the available options FireBug gives, but unfortunately I get the end of chapter12_nodeOne function. Any ideas why? Hello. I'm coding a simple hover-opacity thing for some images on my site on the navigation bar. Although I'm receiving this message in my Firebug. uncaught exception: Syntax error, unrecognized expression: . Here's the navigation code: Code: <div class="navigation"> <a href="home"><img class="home" src="images/navigation/home.gif" /></a> - <a href="home" class="home">Home</a> <a href="news"><img class="news" src="images/navigation/news.gif" /></a> - <a href="news" class="news">News</a> </div> So the effect I've made is, when I hover the image, its opacity gets set to 1. And when I move my mouse away the image changes opacity to .5 And when I hover the text "Home" or "News" the same effect happens with the image. And here's my jQuery: Code: $(function(){
$('.navigation img').css({
opacity: .5
});
$('.navigation img').hover(function(){
$(this).stop().animate({ opacity: 1 },300);
}, function(){
$(this).stop().animate({ opacity: .5 },300);
});
$('.navigation a').hover(function(){
var imageClass = $(this).attr('class');
$('.navigation img.' + imageClass).stop().animate({ opacity: 1 }, 300);
}, function(){
var imageClass = $(this).attr('class');
$('.navigation img.' + imageClass).stop().animate({ opacity: .5 }, 300);
});
});
I can't seem to find the error in my script(s). Any help is appreciated. EDIT: Apparently the error appears when I make anchor tags around the image. Code: <a href="home"><img ... /></a> This gives the error. :S Code: <img ... /> But this doesn't? How can this be? Hey all, Whenever firebug detects a js error on a page, it prevents you from interacting with the page, so you can't scroll, you can't click, you can't do anything except close the window. Anyway around this? Thanks. I'm getting an '$active is not defined' error, which makes sense because the method that defines it isn't called till 10 seconds after I check if it is defined below. But that's the point. I'm actually checking to see if it is defined, and if it's not, then I defined. However, firebug still gives me the error for this: Code: if ($active == undefined) {
$active = $('.paging a.active');
}
var triggerID = $active.attr("rel") - 1;
var image_reelPosition = triggerID * imageWidth;
I also tried: if ($active === undefined) if (!$active) But nothing works. I'm just trying to check if it's not defined, then define it. Yet it won't let me check if it is undefined because it is telling me it's undefined despite the fact I'm checking for that very reason. Thanks for any response. Hey all, Firebug gives me the below error message: component.singularize is not a function [Break on this error] var component = component.singularize(); This is what I have: Code: var component = window.location.hash.replace('#', '');
var component = component.singularize();
alert("The component name is " + component);
var singularize = function(){
if(!String.prototype.singularize){
String.prototype.singularize = function(){
var context = this;
result = ((context.charAt(context.length -1, 1) == 's') ? context.substring(0, context.length - 1) : context);
return result;
}
}
}
Thanks for any response. hi, on my site, http://www.jbiddulph.com/john-drag.html when i move the box within the box, the results are only shown when I click on the firebug icon?! Can someone please help me here? I would like the results to be shown OnMouseUP thanks Hi, I have this web browser which opens up a website that has a drop down list showing values that the user can select. And when I the firebug to inspect the elements in the page, what shows in the inspection window is this: Code: <select id="instance2" name="instance2">
<option value="0">All instances</option>
<option value="1">Item0</option>
<option value="2">Item1</option>
<option value="3">Item2</option>
.
.
.
<option value="23">Item22</option>
What I'm supposed to do is to get the values and update them automatically to the database. I'm actually using HtmlUnit to do this project, and I've heard how I can use getElementById() to get the values. But I don't know how to start. I'm a beginner so I might need a lot of help on this matter. Help is kindly appreciated. Thanks. Hello JavaScripters! I was hoping you could help me with an application I'm working on using C# and the .NET Framework that incorporates Javascript. I'm trying to do something similar to to the FireBug / Firefox Inspect Element featu I came across http://www.selectorgadget.com/ which is exactly what I'm trying to do. It's in Javascript and after looking through the source code for the past 2 hours I still don't have a clue how to incorporate it into my program... From what I can tell it uses tokenizing and recursive analysis of DOM elements to figure out CSS selector paths: http://www.selectorgadget.com/stable/lib/dom.js. Here is what I have so far. The javascript code highlights HTML elements such as a <table> tag and changes the border and background color. Code: document.onmouseover = dohighlight;
document.onmouseout = dohighlightoff;
var BGCOLOR = "#444444";
var BORDERCOLOR = "#FF0000";
// Highlight <table> in grey
function dohighlight()
{
var elem = window.event.srcElement;
while (elem!=null && elem.tagName!="TABLE")
elem = elem.parentElement;
if (elem==null) return;
if (elem.border==0)
{
elem.border = 1;
// store current values in custom tag attributes
//
elem.oldcolor = elem.style.backgroundColor; // store backgroundcolor
elem.style.backgroundColor = BGCOLOR; // new background color
elem.oldbordercolor = elem.style.borderColor; // same with bordercolor
elem.style.borderColor = BORDERCOLOR;
var rng = document.body.createTextRange();
rng.moveToElementText(elem);
// Make a red border around <table>
function dohighlightoff()
{
var elem = window.event.srcElement;
while (elem!=null && elem.tagName!="TABLE")
elem = elem.parentElement;
if (elem==null) return;
if (elem.border==1)
{
elem.border = 0;
// recover values from custom tag attribute values
elem.style.backgroundColor = elem.oldcolor;
elem.style.borderColor = elem.oldbordercolor;
}
}
Any ideas on how to incorporate the Selectorgadget into my program would be greatly appreciated! Selectorgadget Source Code: https://github.com/iterationlabs/selectorgadget Hello, I wonder if someone could help me with this? I want to include a flights search box on a website I'm building and they have given me some JavaScript to produce it. Test page: http://gercia.co.uk/js.html I want to customise the search box but can't see where the css is contained. Can anyone point it out for me? Ok im doing a basic javascript program as i am just starting out.... I believe you will understand what I am trying to do, basically holiday company they have an initial price that the buyer puts in, then asks for age of the person if person <=5 it's free if person <= 15 its initialprice/2 (or I wanted it as a seperate var not sure if thats the best way to go about it though..) else initial price.... the code i have so far for it is.... Code: var initialPrice;
var age;
var halfPrice;
initialPrice =
window.prompt('Please enter the advertised price of the holiday in pounds', '');
initialPrice = parseFloat(initialPrice);
age =
window.prompt('Please enter age of holidaymaker', '');
age = parseFloat(age);
halfPrice = initialPrice/2;
if (age <= 5}
{
document.write('Your holiday is Free');
}
else
if (age < 15)
{
document.write('Your holdiday is ' + halfPrice + '');
}
else
{
document.write('Your holiday is ' + initialPrice + '');
}

Really have no idea why i't wont run.. it's really bugging me as I believe it will be something simple and I just need to know what so I remeber it for next time, any help is MAJORLY appreciated and the sooner the better :) Thanks James (yes i saw the one asking about the same question pretty much a few posts down haha) basically I have some programming doing delphi and pascal and im mixing them up with my very very limited javascript... hence why I think i messed something up.... everything seems to be ok ... but the prompts wont come up or anything.... all the var's match up so what am I doing wrong :( also couple of rules.... im assuming the people inputting are using valid numbers (dont need a check) no need to check for sensible values either dont worry about decimal places (basically the stuff like it checking is for a different part of the assignment that I am doing which i can do by myself if i get this actually working...) While these questions have probably been asked before, separately, I'd like to know how to put them together. What I want to do, is create a link, that goes to an url that I decide, after which, the page goes back to the previous page and refreshes. It would be ideal, if that could be done with AJAX, but that's probably asking too much. Especially if I want to use it for wordpress. hey friend i am trying to use automatic html input creation using java script for my new project .... my problem is the field "type propositon 1:is it answer? ignore this one:" not come into input variable such as $_POST['prop1'] i used PHP Code: pint_r($_POST) and the result was Code: Array ( [radio1] => on [cid] => 65 [desc] => dfdfdfdfd [submit] => Submit ) why my javascript created input field come into role? my php html code is PHP Code: <table> <form action="new.php" method="post"> <tr><td> question type:<br /> True or False:<input type="radio" name="radio1"> Objective:<input type="radio" name="radio2"> Other:<input type="radio" name="radio3" > </td></tr> <textarea name="desc" rows="6" cols="35" ></textarea> <br /> <a href="javascript:add()" ><b>add proposition</b></a> <div id="cat"></div> <div id="num" style="display:none;"></div> <br> </table> and the java script is ...

I have a dataTable in which on the keyup event, the cursor focuses to the next field. In IE7, after a field, the next field is not coming into the view. Please help.

autoTabFocus("SBuy",index);
}else if(ltdBuyUpSelected){

Hey, I was wondering what this tool is called: http://jsgame.mycdn.in/images/screen.png I assume it's some kind of text editor, I've seen it running in Windows and Linux. Thanks for your help I have a form that I am using for several different pages as they are exactly the same... however at the top you must make a choice from the drop down box that then shows the appropriate fields to fill in. Can I make the drop down default to a certain option depending on which page they are coming from? hi everyone, i am on a new computer and without my web designer, expresion web by ms, i want to know if anybody knows of a good, free, lightweight web developer that is good for javascript testing, and not a long download, Hey all, For the below code, I'm just trying to create a simple toggle menu for a Table of Contents.
