Change Button Color With Onclick Function?
Aug 22, 2011
I want to change the color of a button when it is clicked and have added this getElementById line in the function called by onclick but when I add the line the function won't run. The function also contains AJAX to change the button content but everything else is working fine as long as I don't add this line.
Code:
<input type = "button" id = "alternative1" value="$alt1" onClick="changeQuestion('alternative1')">
function changeQuestion(answer)

I have this markup:
[Code]...
There are two radio buttons, sometimes one will be disabled, other times the other will be disabled. I would like to make a script that: First: Changes the color of surrounding text of the disabled radio button to the color grey. Second: Checks the other radio button.
This was my plan: I would make a script that: First: Removes all the current classes and add the class "greyed_out" (or better: change only the color of) the parent element, all siblings and children of siblings (if any) of the radio button that is disabled at that time.Second: Sets the attribute "checked to the other radio button". I made a script, but when I set the bottom radio button to disabled the script doesn't work:

I've been trying to make a default value in a text box go away when clicked.
The general consensus on this forum and on the rest of the internet seems to be that this code:
<script>
function clearText(field){
if (field.defaultValue == field.value) field.value = ''
else if (field.value == '') field.value = field.defaultValue;
[Code]....
But I wonder how I can add a color change to this function. They default value "enter email address here" would be in grey, but when the user begins to type, it would be black. then deleted what'd been typed, back to grey.
document.getElementById(email_box).style.color='#000000'; .....is that too nave..? It didn't work no matter where I put it. And dreamweaver didn't like it when I tried to copy the syntax of the first function, but make it change colors instead. It furthermore hated me trying to assign two different functions to the onClick event.
It also didn't like at all when I tried to apply two classes to the same object..

I'm trying to make buttons that change from one color to another when you click them and change back when you click them a third time. I wrote this page (http://cf.lehigh.edu/ems/test.html) but it only works on Firefox(Not IE or Chome, untested on safari or Opera). I'm using javascript to change the button colors. Is there another way to do this that works universal or another tool such as CSS?

I'm trying to create a cell in a table which changes color depending which radio button is checked.
I found the following code which works for different cells but it doesn't work when the buttons are in the same cell. Think you'll see what i mean. I'm not too hot when it comes to Javascript though so i don't know how to adapt what I've got so far. Code:

I am trying to develop an exam system.Find my code below.I request you to copy the code and save it as an html file .I have 2 problems:
1. Kindly notice that when the quiz is loaded,it shows both the questions by default.I want only question 1 to be visible when the quiz loads.What happens presently is that ,both questions are visible even after I click on the link
Q.1( referring to question 1).However,when I click on
Q. 2,then only question 2 can be seen and then(after clicking on Q.2) if I click on Q.1,then only question 1 can be seen
What I want is that when the page loads only question 1 is visible.Then when I click on Q.2,I can see only question 2 and when I click on Q.1, I can see only question 1.I later plan on adding many questions,so it should be a general solution rather than a solution good only for 2 questions.
2.Also,what I want is that,if someone selects any of the answers of a particular question,it's link color should turn green to indicate to the user that he answered that question.So for,instance,if I select an answer to the first question(select one of London,New York,Seattle,Washington,Chicago), the link Q.1 should turn green.

I want to click a button called 'view report' and then depending on a value of a text field on the page the form will be directed to different php pages.
Code:
<input name="viewreport" type="submit" value="View report"onclick="workOutWhichReport()" />
</div>
[Code]....
I think the problem is that because the javascript has to be outside the form to read the text field value it can't execute on the form properly

I have a function that does some calculations and populates some text fields with the results. I also have a function that changes the font color of the numbers to red if they are less than zero. What I dont have is a way to make them work together. I imagine I need to pass the results of the calculation function to the change color function, but not sure how to go about doing that. Here is the calculation function:
function to calculate the total costs, gain/loss and return percent.

I know it's been addressed before but I don't understand how to implement it on my code.
I want the content on the div 'text' to change every time a new picture loads on the image array. So the first picture would trigger 'THIS IS IMAGE 1' on the 'text' div, while the second image would display 'THIS IS IMAGE 2' and so on.
Here is my code,
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

I have an image with an onclick function and parameters 0, 1. I want to change the parameters of the onclick function through the same function?
<img id="down0" onclick=swap(0,1) />
<javascript>
function swap(a,b){
var imgda=document.getElementById('down'+a);
imgda.onclick = swap(b,b+1);
}
</javascript>
Normally it should change the onclick to swap(1, 2) but it remains 0, 1.

have been trying to rework this to call additional, independent sets of colors to cycle through (so it would loop thru a set of grays, a set of primary colors, etc). I would use perhaps a different function name in the HTML to call different sets of colors. If this is more complex than I think it is, I think 3 sets would be plenty. demo link of script in current state at bottom)
<html><head><title></title>
<script language=javascript>
colors = ["#cacdca", "#b2b4b2", "#969896", "#7d7f7d", "#ffff00"];
cRGB = [];

Trying to click (onClick) an animated gif image of an on/off switch to start a second animation which is located on a different location on the web-page (a 7-frame animation of a generator with moving parts) immediately followed by a random image selection function placing an image in a 3rd location on the page (next to the generator image). The random images are supposed to look like the result of the generator animation---the item that �pops out� of the generator.
We thought the process to achieve this would be an �OnClick� on the on/off switch-animated-gif to start two javascript functions (generato animation function & random image function). To further complicate matters, we are doing this website in iWeb. We�re using iWeb SEO Tool to add the javascript to the header and HTML snippet in iWeb to place the HTML code. Not sure we�re actually doing the snippet right though---is it supposed to relate to the images---or is it separate? When the gifs are place on the iweb page, they work in the browser upon page load---the �on-click� & the random image function are NOT working...so we know we�ve done something(s) wrong.
We�re thinking that we�re probably missing some code that describes where the 3 different image-spots are on the page (image #1 is the on/off switch gif, image#2 is the generator gif, image#3 is the generator output.png)....or just aren�t coding the string of functions correctly---or maybe our strategy for achieving this is just no correct (?).Here is the code we have tried that didn�t work.

script language = JAVASCRIPT>
<!-- Hide script from old browsers

I have a form which contains FOUR text fields (e.g. TEXTFIELD1, TEXTFIELD2, TEXTFIELD3 & TEXTFIELD4). Each text field holds a HEX,DEC color value. ABOVE this form I have a table with TWO ROWS (ROW1 and ROW2). ROW1 should correspond with TEXTFIELD1, so that when the VALUE in TEXTFEILD1 is changed the background color of ROW1 will change to match the HEX,DEC VALUE entered in TEXTFIELD1. The same would happen with TEXTFIELD2 and ROW2. TEXTFIELD3 should be used to change the color of the TEXT inside ROW1 and TEXTFIELD4 should change the color of the TEXT in ROW2. I also wanted to know if it would be possible to achieve this without clicking any button.
------------------------------------------------------------------
| ROW1 | TEXT IN ROW 1
------------------------------------------------------------------
| ROW2 | TEXT IN ROW 2
------------------------------------------------------------------
TEXTFIELD1 <----HEXDEC VALUE GOES HERE to change color of ROW1---->[code]....
