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 )
I have 3 sum fields which I want to change to a red colour if the value is > or < 100. Apparently this is a DAP, but I am using javascript to tweek some of the settings in DAP.

I want to implement a text input box for SMS text messages and the messages are limited to 160 characters (including spaces, etc.). I would like the font color of the text to be green as the user types and any text beyond 160 characters to be red. I would like to do this with one input box, the same box that the user is typing in not a separate display box. This will be on the users local PC it won't be on the Internet.
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 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 am trying to change the colour of the text in my menu bar, i know you can do this with css or jquery but i want to try and do it with javascript in an external script sheet. I want to use the onmouseover and onmouseout functions to change the colours, and i want it so their are different colours for each menu item.
I try and edit other peoples free codes, Ive got some input boxes and I want to change the colour of them, they are the default white, I want them transparent, there is no code I can see that says its colour, I'm not sure what to change or put in so I can make the white part inside the input field transparent
Here is my script. you will see some white boxes, its this I'm trying to change colour.
onChange it filters the results by either New/Old. What i would like to do is to change the colour of the select box to show that an option has been selected. I.E after i select New the results are filtered and the select box changes colour.
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).
I'm trying to use javascript to have my webpage black at night and bright blue (#2A7FFF) in the day time. How would I go about this? ::confused: I have also tried to use javascript to change a picture depending on the time of day, this is what I have used.

I've been using this bit of code to limit the number of characters in a text field (taken from http://www.shiningstar.net/articles/articles/javascript/dynamictextareacounter.asp:
<SCRIPT LANGUAGE="JavaScript"> function textCounter(field,cntfield,maxlimit) { if (field.value.length > maxlimit) // if too long...trim it!
