Change The Colour Of The First Word In An H2 Element

Feb 25, 2011

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?

Border Around An Object - Change The Background Colour And Font Colour Of Some Elements

Sep 22, 2009

I am using javascript code to change the background colour and font colour of some elements called 'filled') dynamically. For example:

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"

Storing An Element's Colour As A Variable?

Jun 4, 2009

I tried and tried for so long to get this to work, but I just can't.

Here's what I did:

var testvar = document.getElementById('example').style.color;
alert(testvar);

Not only would the alert come up empty each time, but IE reports that "testvar" is undefined. Why isn't it working? And if I'm going about it the wrong way, how can I store an element's style info, such as font colour like in this example, as a variable?

JQuery :: Change Colour On A Class?

Jul 9, 2010

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

Font Colour Change In Textarea

Nov 29, 2011

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 )

JQuery :: Making A Button Change Colour On Clicks?

Nov 11, 2011

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 To Change Background Colour Of Form Input Field As Soon As Thevalue Is Changed?

Oct 1, 2006

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.
