Dynamically Change The Colour Of The Numerical Meter Readings
Oct 23, 2011
How to use JavaScript to dynamically change the colour of the numerical meter readings to show if they are above or below the target value entered by the user in a text box on the page.Those below should be shown in green,those above in red and identical values may be shown in amber.This functionality must be completed client-side without a page submission to the server.You must consider putting the values in a particular tag and then using the getElementsByTagName() JavaScript method.

At this point I have been able to add the row. But what I want to do and am having trouble with is alternating the row colour to the dynamically added row element.
Sample of code I am using:
Code:
var tbody = document.getElementById('tableItems');
var row = document.createElement("tr");
var remainder = tbody.rows.length % 2;
if(remainder) {
row.setAttribute("class", "rowLightGreen");
}
var td1 = document.createElement("td");
td1.appendChild(document.createTextNode(qty));
td1.setAttribute("class","qty");
row.appendChild(td1);
tbody.appendChild(row);
One thing that puzzles me, is that even after adding a row the table my table.rows.length still = 0.
Does anyone know how I can determine the appropriate amount of rows so that I can apply the appropriate class?
Or is there just something blatantly wrong in my approach?

I am using javascript code to change the background colour and font colour of some elements called 'filled') dynamically. For example:
if(timeInputValue >= startcode && timeInputValue < endcode && stateInput.value == "playing") {
filled.style.backgroundColor = '#ffffff';
filled.style.color = '#000000';
}
I also want to put a border around these 'filled' elements too - how can I do this is javascript? I can't find an equivelent to style.border = "1px"

How do I do this? I've set up javascript to change the background colour depending on what colour square the user clicks on, this is working fine.However, I want to be able to set an initial colour, other than white, and then let the user chose their own.
here is my code so far.
<script language="JavaScript">
<!--
function changeBGC(color){
[code]....
I want the page to be initially set to the brown colour, then I want the user to be able to choose their own colour.

I have this script which, on mouseover, shows a nested element of a class.
I want to add a snippet which, on click, changes the color of the class... maybe with a fast fade.
Does it require creating a second class with the new color? Something like:
$(document).ready(function(){
$('.class').hover(function(){
$(this).find('.bit').show();
}); //existing script
[Code]....

I am trying to add some styling to the first word of all of my H2 headings.
Now obviously this would be very easy to do using a span, but let me clarify my situation.
I am working on a Joomla! site, so a lot of my code is read from php and sql files. I thus can't go and wrap my text in a span by hard coding it since it is dynamic and read from a database.
I thus decided that manipulating it using javascript will be the simplest. The only other chice is to write a php script that does pretty much the same thing, but I prefer javascript.
So here is what I am thinking of doing:
I want to select all of the H2 elements from my document, get access to their text content, single out the first word, and then wrap it in a span. The span will have a class, which will then simply be styled using CSS.
I though I was on a roll, but is seems that I have hit a snag. I am able to select and edit a single element with an id, but not all of the H2 elements in my document.
I was using 'getElementById' and assumed I could simply change it to 'selectElementByTagName' at some point.
I then used 'innerHTML' to retrieve and manipulate the contents.
Here is my code so far, and it work to some extent:
Code:
It seems though that 'innerHTML' does not work with 'selectElementByTagName', and I can't seem to find a similar command that does.
I also can't use ID's since I can't manipulate the HTML (at least not without scratching through a whole mess of php). Even then I need to manipulate various elements on one page, so ID's are no good anyway.
So my question finally is this: Is there a similar command I could use, or am I busy going in the wrong direction?

I want a set up some type of array/ IF statement within a textarea.
This is what i want it to do...
If textarea text = "[example]" then change colour of font #383838
I need it as a basic validation method to ensure the user has typed in the correct text. for example if the member uses { in stead of [ it will not turn a different colour and the user ill no they have not typed it in correct.
I presumed there would be some JQuery code out there that would enable this but I can't find it. ( or even know what search term to use )

How would I go about changing the colour of a div, using a list-box, as opposed to buttons? I think I have figured out how to create the list box, but I am stumped as to what to do using Javascript.
Looking on Google, there is no much help on what I am trying to do (e.g. there is only code on changing div colours via an image hover etc).

How can I change the font colour in the input fields such as the example below?
The default text for all input fields are set to be black by default in CSS.
But I want to set the font colour of input fields for First Name and Last Name to be grey by default, they input text will be black like other fields when the text is type in.
I put this line in my jquery code below but it doesnt change anything obviously,
this.value.css({color:'#999999'});
Code:
<input name="message_name_first" id="message_name_first" type="text" class="field field165px_width"/>
<input name="message_name_last" id="message_name_last" type="text" class="field field165px_width"/>
[Code]....

I'm wanting to have a button on a web page where if I click on that button it changes colour. Basically I have 3 images of leds being on, a green a yellow and a red. Depending on the state the normal running state would be green and if there was a problem I could make it yellow and if it was off make it red.
Rather than having 3 different buttons, I want to have 1 that can change when clicked and just cycle through the 3 colours.

How do I change the background colour of an input box in a form as soon
as the value is changed? Also the background should revert back to it's
original colour if the user decides that they do not want to make any
changes and hence retype back the orginial value.
I do not want the background to change after the user has moved to the
next form field but as soon as the value has been changed.
