Alternating Background Colors: JS V PHP
Oct 24, 2010
Out of pure curiosity: Assuming tabulated data in HTML is being generated by a PHP script, would it be better to alternate each row's background color with PHP or rely on JS to do it? One is run client-side and the other server-side so my guess you have to take the whole web app as a whole and see which side should be spared the additional workload. Is it situational or is there an absolute rule? In a vacuum, I guess you could argue PHP would be better since it cannot be turned off in the way JS can (unless plugins like NoScript can block PHP as well), but I don't have enough experience with either to be sure.

I read this article: [URL]...I want to Combine this example with the example given in Part 1 to give this table of revenues alternating row colors!
Here are my combining codes: It is quite clear there must be something with them because I can't see the expected result after running. Help me find that mistake.

I'm using a javascript to alternate table rows and it works fine by table id, and on the first loop. This is all inside a conditional, in which the table tag is repeated.
On the second and subsequent loops, the alternating row color fails because there can only be one unique id call to a page. Right?
What's the script that will allow unlimited reiterations of tables with alternating row colors, using class?

I have a form which displays correctly in FireFox. In IE, 2 of the 3 fields appear with a pale yellow (#FCFEA4) background color. Why is this, and how can I fix it?
There is only 1 style sheet, and everything else conforms to the sheet. Remember: this problem is in IE, not FireFox. My task is to make it render correctly in IE.
<FORM ACTION="/bbp/t11s.php" METHOD="GET" name="lastform">
<div style="padding-left:10px;font-family:monospace;">
First Name <input type=text value="" name="fname">
</div>
<div style="padding-left:10px;font-family:monospace;">
Last Name <input type=text value="" name="lname">
</div>
<div style="padding-left:10px;font-family:monospace;">
Building <input type=text value="" name="bld">
</div>
<br>
<div style="padding-left:75px;"><input type="Submit" value=" Post Information " /></div>
</form> Code:

I seem to be having a slight problem.
Code:
<script type="text/javascript">
<!--
document.bgColor='#33CCFF';
var x = 300;
while (x < 1500)
[Code]...
Basically, this makes the background flicker for a brief second. Great. However, if I set a background color using CSS (so the page isn't white if javascript is turned off) the flicker won't work.

Alright so for a school assignment I need to create a button with the name of the color it is going to turn the background to. the assignment says nothing about naming the buttons the hex numbers for the color therefore: I was curious if someone could show me how to create a button in java script that would generate a random hex number for a color ie: #+()+()+()+()+()+() and the text shown on the button would be the same as the hex number generated.

I want to have <div> cells that the background-color css style dynamically change between 4 colors depending on how many times they are clicked. The options are none, yellow, red and green then repeat. So when the page loads, they are all at none, and if you click once it goes to green, twice to yellow, three times to red, then back to none.

what I'm trying to do is, when a user hover overs an element, in this case, a li within a div, I want the background color to animate to a different color besides the background color of the body (in this case, black).
It works, but the behavior is erratic. For instance, yes, the color will change when I hover over the element but it when I'm within the div ul li, and hover over for instance the paragraph, the background color of the element will animate 2-3 times.
Actually when I move around any element within that UL the animation will flicker, how would I go about stopping that?
Also sometimes, not all the times, on pageLoad, the animation will fire.
Here's the code.
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

so I have this script that alternates my CSS stylesheets and it's working great. The thing is, there was a cookie coding that was included but it doesn't work. Basically what I want to do is that the browser remembers which stylesheet the user had chosen and keep it the same for all pages, for a determined period of time.
Here's my code:

I am new to JavaScript and have been plugging away at it trying build a menu for site I am developing. My colleague has suggested I use Flash, which I could, but I think it is unnecessary and JavaScript is ideal for this use.
I have been building a menu that has a sub menu that appears below all of the main menu items. I have got this working and will include the code I used to do this below.
Now I want to change the button image so that it is visible which sub-menu the items that appear below belong to. Code:
which was very helpful and with some playing around I can now get my existing menu to complete part of my task. But I have 4 menu items and therefore need to use a "var" command to allow me to define different button images for different menus. Code:

I am working on a Windows application (in C#) that displays some HTML. In one place the HTML is a status window. What happens is the static HTML page is embedded into the application. The static page displayed and then the C# code gets a hold of the HTML DOM from the web browser and updates what pieces need to be updated.
What I need to do now is change the colors of everything on the static page. At present there is an embedded CSS style in the HTML and all the colors are defined there. Using the DOM, via C# code, how do I change the colors of everything?
1: Can I simply update the CSS and it will auto magically happen? If so, how does one update the CSS via the DOM?
2: Do I need to go to each individual item and change the color there?
3: Is there a better way to do this all the way around?

I just read "JavaScript 101 - Part 1," and had a question about the specific part linked to above:
Is there a more efficient way of switching colors every row other than calling it every time you want to start a new row? Also, how can the row number be increased each time if the variable rownumber is only increased by one within the second half of the function? What if the row is even? Is the number not increased? Code:

I want to run a script that will cycle through all the available colors, but can't even get the following to work:
<html>
<head>
<script type="text/javascript">
function setStyle()
{
i=255;
[Code]....
What am I doing wrong? Eventually I want put all the above in a loop that updates 1,j, and k - and so cycles through all colors.

I got 3 sections on the site, at the bottom of each are 5 bars which are used to change the text color. I'm trying to minimize the code, so I created an array which contains all the colors, but I'm not sure where to put the call to the array. If I put it in the for loop, the selected color will always be green no matter which color you click. The bars should also go up to 40px when clicked and when the next bar is clicked the current bar at 40px should go back to it's originals size(20px)
this is the JS
var colors = new Array(4);
colors[0] = "#ed1c24";
colors[1] = "#736257";
colors[2] = "#620460";
colors[3] = "#e87e01";
colors[4] = "#00a650";
[Code]....

I'm writing a FireFox extension and I have the dom and therefor the
links[] collection
window.getBrowser().contentDocument.links[i]
Is there a way to change the color of these links based on the stuff I'm
checking for from the JavaScript?
For example. If I have this loop
var number_of_links = window.getBrowser().contentDocument.links.length;
for (var i=0; i < number_of_links; i++)
{
var domain = window.getBrowser().contentDocument.links[i].hostname;
//Check hostname here and change color
}
how could I change the links color?

I need to make the backgrounds on certain rows a different color to get the info to read better. I used the following:
<!-- Directory of Staff Row Backgrounds -->
<script type="text/javascript">
$(document).ready(function() {
$('tr:odd').addClass('odd');
});
</script>
But instead of starting over with a new table it seems to just have counted them all so it looks off. Here is the page: [URL].
