Creating A Checkerboard - Consists Of An 8 By 8 Grid Of Black And Red Squares
Sep 28, 2009
I am to create a checkerboard which consists of an 8 by 8 grid of black and red squares in which no two squares of the same color are adjacent. Write a graphics program that displays a checkerboard.
When I compile this I receive an error Checkerboardwindow.java:14: 'class' or 'interface' expected
Checkerboardwindow.java:18: 'class' or 'interface' expected
The first coding is my CheckerboardWindow and the second coding is Checkerboard...

I have been struggling with a loop of mine. The loop should create a grid, of 204,000 squares(div's). And the total would create a grid field of 340 pixels by 600 pixels. All div's are sized 1 pixel.The idea is to create a grid, that shows temperature data in a gradient style, like a weather heat map. The data is collected from temperature sensors which are connected to a database.The only problem is that because it's such a massive amount of calculations to be calculated by javaScript, the whole thing freezes. Here is a sample of my code:
Code:
function makeGrid()
{
for (var i = 0; i < 8160; i++)
{
[code]....
Another problem is, the grid should be reloaded every 5 seconds or less.Because that's the interval used by the temp sensors, and for the usage that's planned for the project, its really important that the data is constantly up to date. using another web based language are welcome, as long as they are combinable with PHP or AJAX. Or maybe there is a ready to use library that I dont know of. Couldn't find anything for jQuery.

I am looking for creating a grid/table that is editable online. I have browsed online for solutions, but I am short of time & I seem to getting more confused the more I search.
Basically I am trying to create a staff rota that the admin staff can edit online and save out so it is viewable - but not editable by staff members.

I am creating a grid of thumbnails. When a user hovers over a thumbnail, the image enlarges. The *trick* is, I want the "active area" to only be the size of the thumbnail. That is, the thumbnails are 180x120, and when the mouse leaves that area, I want the large image to shrink back to normal size.
I have a working demo here:[url]
The way I accomplished this feels hacky though, and I's like to know if there's a simpler/more elegant way to accomplish it. The thumbs are an unordered list of images.
Here is my javascript:
In essence, I add an overlay div over each thumbnail which acts as the trigger to shrink the enlarged image. I thought I could use the parent <li>, as it doesn't appear to expand with the image (since I've set its size in my CSS) but that didn't work.

I have a question for flexigrid jquery grid control users.
I am able to display json data returned from my WCF service in my Flexigrid in my application.
The paging toolbar displays correctly and it's clear that the paging toolbar understands how I've configured it.
However, the grid is not actually implementing the paging filter on the data in the grid. For example, the paging toolbar says "Displaying 1 to 10 of 12 items". However, all 12 items are displayed in the grid.
I guess I'm missing a config setting or callback. Any idea what the problem might be?
Here is my grid config block:

I have got a DIV that I need to refresh, its content consists of an image that will change on the insertion of a row to the SQL Database, however, when I use a refresh on my div it does refresh but does not change the image...
My refresh code is ajax:
And my PHP code contains the MYSQL that has a mysql_num_rows, so that PHP can see if there are rows or not.
I would like my page not to redirect or refresh on my div change.. So I would just like my div to refresh.

I'm trying to make a web page that will have an extremely simple minesweeper, where a 2x2 grid is created and only 1 square will have a mine. Upon clicking the squares and no mine is present the square turns green and the square with the mine turns red. I cannot get the squares to stay their respective color once clicked.

In this game i have the letters as images and they are listed at the top in two rows.
This is the code
As this is not really the best way to do it, I was wondering if i could set the letter squares to be objects of a Button class. I just don't know how to do it.

I know this is a known issue but I have had no luck with finding a fix for the issue I am getting with IE8. I get a nasty black border around my png that I am using the Jquery fade function. Does anyone have any useful hacks/tricks to fix this?

I have two grids, they both display buttons. One grid displays numbers, true or false and yes or no, and the other grid displays letters, true, false, yes and no.
The second grid is not displayed in the code (used css to not display second grid buttons (.answerBtns)) Now using the getButtons() function, if the user selects button "1" in first grid (the grid which you have to open using (Open Grid) link, then it should display button "A" in second grid, if user selects button "2" in first grid, then it should displays buttons "A" and "B" in second grid, if "3" then display "A", "B" and "C" and so on.
Now except using if statements and stating which buttons should be displayed and not displayed depending on the button chosen in first grid, is there a more efficent way of coding this so that the display of buttons in second grid depends on what is selected in the first grid?
If it is using an array can somebody show a sample of this in their answer. You can just do it for one example and then I should be able to use that to fill it for the other buttons.

I taught it to myself without even having any true JavaScript experience and am sure that while functional, many of my implementations could/should be written completely differently. I'm running some animations that look great in everything except for IE. In IE I'm seeing a thin, ragged black border around some of the elements that I'm animating.

When the site loads it takes a while for all the scripts to load and then the images to settle down - more so in IE, naturally. I would like to display a black screen or cover everything with a div while it settles down. I have tried a few Timeout scripts but they appear to be conflicting and don't work. how I can either display a blank screen while it all settles down or just avoid the problem all together.[URL]

I'm using a feature carousel on my new website - this is a horrible test version but take look and you'll see my problem - [URL]... It works fine in Chrome, FF and IE9 - however in IE8 and IE7, on the fade, an ugly black outline is added to the transparent PNG.
Does anybody know how I can remove the black outline in IE8 and IE7.

What I would like to do is enable swapping between the black images? I would like to drag and drop to another image and that image will fill up the dragged earlier image position?

I created a button with 2 states for mouse-over effects using css sprites. This has always worked well and I have no issues. I recently added some jquery to my buttons to create a smooth transition for the mouse over and this is where I see the issue. When the page is initially loaded the image looks fine. When I hover over the image there is a brief flash of black around the transparent edges then the transition begins and everything looks okay. When I un-hover the image shows the black edges. From this point any time the image is in the un-hovered state the edges are black, and when I hover the black goes away.
Example: [URL]
Here is the jquery code:
$('p.rss-button a')
.css({ 'backgroundPosition': '0 0' })
.hover(
function(){
$(this)
.stop()
.animate({
'opacity': 0
}, 325);
}, function(){
$(this)
.stop()
.animate({
'opacity': 1
}, 325);
});

I'm trying to create a slide show using the script here:[URL]Here's my page.[URL] The problem is in IE (I'm testing this in IE7) there is a small black rectangle that displays in the fade. (I've tested this in Opera, Safari and Chrome. It works in all. I also tested it using an IE tester [URL]. Only 8 and 6 versions work correctly.) I can see on the dynamic drive page the slide show works correctly.I've tried changing the "background='black'" in the .js in a variety of places to transparent and tried to put an image, a transparent .png, in place of the background. No success with either one.

I'm having trouble getting FireFox 2 to play nicely with a jQuery fade. Here's a paired-down example:[URL]..I've made the source code VERY basic here to make it clear what's what. When you click the link, some jQuery fades the image in and out. But it also makes all the text go thinner. Clicking away from the link then sets the text back to how it was.
Any ideas why this could be? I've googled it and although I can find people with issues around jQuery's fades, I can't seem to find a solution to this one.

When the page loads for the first time or after refresh the text within the scroller is black for a brief time and then it turns to white. I have tried changing the values but can't get it to start with white text?
The other thing is I would like to be able to have a hypertext link within the text but I tried using the normal <a href> tags but this doesn't work. Can you see a way of doing this? Code:

Should work on IE5.5+ and recent Mozilla clones.
Download size ~30K
Open source (GPL license)
Not released yet, no API documentation (will be soon)
Basically the question is - does it make sense at all? What's your current experience with client-side widgets - too slow, too heavy or there is still a place for things like that?
