JavaScript - Javascript To Set Bg Colour And Than Change To Another Colour On Click.
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){ document.bgColor = color; } //--> </script> Then on the buttons: <a href="#" onclick="javascript:changeBGC('#486970')"><img src="images/blueSquare.jpg" alt="a" width="25" border="0" /></a> <a href="#" onclick="javascript:changeBGC('#dd737b')"><img src="images/pinkSquare.jpg" alt="x" width="25" /></a> <a href="#" onclick="javascript:changeBGC('#4f814e')"><img src="images/greenSquare.jpg" alt="cx" width="25" /></a> <a href="#" onclick="javascript:changeBGC('#594b31')"><img src="images/brownSquare.jpg" alt="s" width="25" /></a> <a href="#" onclick="javascript:changeBGC('#ffffff')"><img src="images/whiteSquare.jpg" alt="x" width="25" /></a> 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. Thanks for any help. Similar TutorialsHi Guys, I have a little question... I know that adding Code: onclick="document.body.style.backgroundColor='#F3B90C'; to a div will change the body background colour to the above colour.. But what I was wondering was this.. Is it possible, instead of adding the code to the actaul div itself to pass the function like this... Code: <script type="text/javascript">
$("Object").click(function(){
document.body.style.backgroundColor = "#000000";
});
</script>

Thanks Hi 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. Can anybody help me? Hi All I'm trying to get a drop down box to change the colour of more than 1 td cell at a time. I can get the boxes to work with single cells but not more than one.

Hi, Sorry to bother you all with this but I'm really new to JavaScript and can't figure this out but I'm sure it's probably quite simple for you guys. 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/...reacounter.asp: Code: <SCRIPT LANGUAGE="JavaScript">
function textCounter(field,cntfield,maxlimit) {
if (field.value.length > maxlimit) // if too long...trim it!
field.value = field.value.substring(0, maxlimit);
// otherwise, update 'characters left' counter
else
cntfield.value = maxlimit - field.value.length;
}
// End -->
</script>
<form name="myForm"
action="/articles/articles/javascript/dynamictextareacounter.asp?ID=<%=siteID%>"
method="post">
<b>One Function to Count and Limit Multiple Form Text Areas</b><br>
<textarea name="message1" wrap="physical" cols="28" rows="5"

onKeyUp="textCounter(document.myForm.message1,document.myForm.remLen1,125)"></textarea>
<br>
<input readonly type="text" name="remLen1" size="3" maxlength="3" value="125">

</form>
What I'd like to do is make the background colour and maybe the font colour change on the 'characters left' field depending on the value of that field. So most of the time the colour is green but when the field = 0, the background colour changes to red. Can I just add to the function above or will I need a new one? If anyone could help, that would be great Cheers how to change placeholder text colour in javascript? Code: <script> // this is inside a html form form['height'].placeholder+="enter password"; </script> how do I change the text above from grey to a different colour? Also, how do I check for isnotanumber in a form submission? Code: if(isNaN(form['weight'].value)) {
console.log('use a number');
it still outputs that console.log error!!!!!!!!! Dear All, I have tried to change the text colour and size but with no successful. I have two files.

Any suggestions on how to add the colour within the loops Hi All, I quite new to JavaScript and find myself stuck while trying to change the background colour of an input box. I have an external js file and everything seems to work perfectly but for some reason I cant get the colour to change. Any help is REALLY appreciated! Code:
function validateID(id, name, value)
{
var regEx = /(abc)/;
var result = regEx.test(value);
alert(value + " " + result + " " + regEx + " " + name);
if (result == true)
{
userFeedback(id, '<--Input Is Valid');
document.getElementsByName(name).style.backgroundColor='green';
}
else
{
userFeedback(id, '<--Error: Input Is Not Valid');
}
}

In order to separate the concerns (content/style/behavior) you should add/remove a class to the element and apply styles with CSS using that class as selector. Every contemporary browser has a developer console built in, look into the JS console and see if there are any errors coming up. Other than that, it helps if you posted a link to your page so we can see ourselves without having to guess. Reply With Quote 01-12-2015, 11:59 AM #3 murtagh View Profile I'm just trying to do something pretty simple which is an alert box which will give me the background color. So simple...that it doesn't want to work, that is! The line the body is onmouseover: Code: <p id="metallic" onMouseOver="switchElementColour('metallic');">metallic c-prints</p>
The function is as follows Code: function switchElementColour(elementName){
var tryId = document.getElementById(elementName);
var yrf = tryId.style.backgroundColor;
alert(yrf);
}
I've tried a number of different variations, including: messing with the quotes 'hard coding' the id ("metallic") in the function (although I don't want to leave it there) changing the code around based on stuff found online ...but I keep coming back to the above. The result is a blank alert box (no errors, just blank). The element name is getting passed, because when I create an alert box in the function that looks like this: Code: alert(elementName); The result is an alert box that says metallic (no quotation marks). Au secours por favore? Hi. I am looking for a way to have a button that toggles the background colour of my website. So for instance, I will have one button called 'switch to light', when its clicked it switches the colour of the background to a light colour, and another button replaces this that says 'switch to dark', and so on. The main problem is I have no idea how to store this information when the user is on the site so when the page is refreshed the colour is remembered. I am a complete newbie to Javascript, so any help will be greatly appreciated! Thanks Hey guys, I have a colour picker on my site, see it at http://www.ludatha.com Now I want to change the colour of the links on the page, don't worry I know how to do all this. It's just if someone chooses full black (#000000) the theme looks awesome, but the links on the dark background are invisible. Similarly if someone chooses full white (#ffffff) then you can't see the text on the white background. So I want to know if you geniuses can make it so when a variable containing a hex, like #000000 is set as the main colour, then the link colour is changed to #666666 so you can still see it, but I want it to work with colours, so if you had #360000 (dark red) then the link colour would be something like #a10000. I know this is possible, somehow... I hope I have explained it well enough for you to understand, here is my code to change the background: Code: onChange: function (hsb, hex, rgb) {
$('.colour-picker-colour').css('backgroundColor', '#' + hex);
$('.background').css('backgroundColor', '#' + hex);
$('.colour').css('backgroundColor', '#' + hex);
$('.colour-text').css('color', '#' + hex);
$('a .colour-text').css('color', '#' + hex);
$('.colour-text-hover:hover').css('color', '#' + hex);
$('.tabs a:hover').css('color', '#' + hex);
$('.seperator').css('backgroundColor', '#' + hex);
$.cookie('ludatha_colour', hex, { expires: 365 });
}
P.S. My site may not look right for a few hours as the images and CSS is updating. I have a JS that works, but only on the first Dynamically created check box and once the colour has chaned it wont change back when clicked again Please inspect my code to see exactly what I mean ... Code: <?php
function create_time_range($start, $end, $by='30 mins') {
$start_time = strtotime($start);
$end_time = strtotime($end);
$times = array();
for ( ;$start_time < $end_time; ) {
$times[] = $start_time;
$start_time = strtotime('+'.$by, $start_time);
}
$times[] = $start_time;
return $times;
}
// create array of time ranges
$times = create_time_range('0:00', '23:00', '1 hour');
// $times = create_time_range('9:30am', '5:30pm', '30 mins');
// format the unix timestamps
foreach ($times as $key => $time) {
$times[$key] = date('H:i', $time);
}
//print '<pre>'. print_r($times, true).'</pre>';

'Sunday',

I am at my wits end and have spent over 2 hours looking into this... Hello All I was hoping you guys can help. I have 3 radio fields which when clicked on I want it to change the background colour of the table its within. The radio fields have the same name so only one can be selected at once. At the moment its changing the background yellow but if I click another radio field its not resetting back to normal (white). Im not sure how to achieve this is javascript... Here is the code im using now: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<script type="text/javascript" language="javascript">
function swapColor(oCheckbox) {
var pop = oCheckbox, checkedcolor = 'yellow';
while (pop.nodeType != 1 || pop.nodeName.toLowerCase() != 'table')
pop = pop.parentNode;
if (typeof pop.oldcolor == 'undefined') pop.oldcolor = pop.style.backgroundColor;
pop.style.backgroundColor = (oCheckbox.checked) ? checkedcolor : pop.oldcolor;
}
</script>
</head>
<body>
