JavaScript - Change Div Background Using Javascript
I currently have a web site in which I am using some Javascript to change the Background of a DIV.
The DIV is defined as follows : <div id="outerscreen"> <div id="mainscreen"> </div> </div> and the Javascript I am using is as follows : var docEl = document.getElementById('outerscreen'); docEl.style.backgroundImage = "url('pics/intro.gif')"; My problem arises where this function works perfectly on IE but fails for Chrome, FF and Safari. Can anyone shed any light on what the problem is and how I might be able to resovle this. Thanks in advance Chris Similar Tutorialscan you explain someone step by this code?i didn't get it. <script language="Javascript"> <!-- function backcolor(form){ temp = "" for (var i = 0; i < 16; i++) { temp = form.color[i].value if (form.color[i].checked){ document.bgColor = temp } } } function randombackground(){ document.bgColor = getColor() } function getColor(){ currentdate = new Date() backgroundcolor = currentdate.getSeconds() if (backgroundcolor > 44) backgroundcolor = backgroundcolor - 45 else if (backgroundcolor > 29) backgroundcolor = backgroundcolor - 30 else if (backgroundcolor > 15) backgroundcolor = backgroundcolor - 16 if (backgroundcolor == 0 ) return "olive"; else if (backgroundcolor == 1 ) return "teal"; else if (backgroundcolor == 2 ) return "red"; else if (backgroundcolor == 3 ) return "blue"; else if (backgroundcolor == 4 ) return "maroon"; else if (backgroundcolor == 5 ) return "navy"; else if (backgroundcolor == 6 ) return "lime"; else if (backgroundcolor == 7 ) return "fuschia"; else if (backgroundcolor == 8 ) return "green"; else if (backgroundcolor == 9 ) return "purple"; else if (backgroundcolor == 10 ) return "gray"; else if (backgroundcolor == 11 ) return "yellow"; else if (backgroundcolor == 12 ) return "aqua"; else if (backgroundcolor == 13 ) return "black"; else if (backgroundcolor == 14 ) return "white"; else if (backgroundcolor == 15 ) return "silver"; } // --> </script> I have a div that changes background on click.

Hi, what I want to do is create a menu with rollover buttons but each button also changes the background image of a div. I've managed to change the colour of the div but not add an image there. I've added my code so you can have a look. Case 0 shows me attempting to change the background image. I must be doing something wrong. I've left the other cases as colours so you can see how I did that. I eventually want it all to be images. I'm creating a Joomla website (not sure if that makes a difference). Code: <body onload="addHandlers()">
<script type="text/javascript" language="javascript">
function addHandlers(){
var allMenus = document.getElementById("services_menu").getElementsByTagName("li");
for(var k = 0; k < allMenus.length; k++)
{
allMenus[k].setAttribute('onmouseover', 'ChangeContentBg('+ k + ')' );
allMenus[k].setAttribute('onmouseout', 'Reset()');
}
}
</script>
<script type="text/javascript">
function ChangeContentBg(i)
{
var Num = parseInt(i);
var ContentDiv = document.getElementById("content");
switch(Num)
{
case 0:
ContentDiv.style.background-image = 'url(../images/waxingtinting_rollover_image.jpg)';
break;
case 1:
ContentDiv.style.backgroundColor = 'red';
break ;
case 2:
ContentDiv.style.backgroundColor = 'purple';
break ;
case 3:
ContentDiv.style.backgroundColor = 'green';
break ;
case 4:
ContentDiv.style.backgroundColor = 'yellow';
break ;
/*For each new color you would have to add a new case and change ChangeContentBg() parameter , to the case you want in <li> tag*/
}
}
function Reset()
{
document.getElementById("content").style.backgroundColor = '';
}
</script>
Hi, I am trying to work out a code where I can change the background colour of an HTML page via external JS page. Please note that I will be using different HTML pages with different colours so have to use Arrays. Here is what I have so far!!! here is my function, <script language="JavaScript"> var backColor = new Array(); backColor[0] = '#000000'; backColor[1] = '#111111; backColor[2] = '#222222'; backColor[3] = '#333333'; function changeBG(whichColor){ document.bgColor = backColor[whichColor]; } </script> ------------------------------------- What I need is to apply changeBG function to my HTML page using colour [0] Any help would be greatly appreciated! Hi 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>
Any help/info is appreciated Kind regards, paffley Hello. The code below lets a user select a drop down option and a picture changes depending on the selection. I am trying to make it so when you select an option on the dropdown the picture shows up in the center of the screen and in the background behind the text. Here is the code. Code: <html>
<head>
<style type='text/css'>
#txt {background-repeat:no-repeat;width:200px;height:200px;}
</style>
<script type='text/javascript'>
function div_bg(team){
document.getElementById('txt').style.backgroundImage="url(images/" + team + ".jpg)";
}
</script>
</head>
<body>
<select name='team' onChange='div_bg(this.value);'>
<option name='arsenal' value='arsenal'>Arsenal</option>
<option name='liverpool' value='liverpool'>Liverpool</option>
</select>
<div id='txt'></div>
</body>

Nothing happens. What am I doing wrong? Hi , I have 5 or 6 textboxes and all of them are required ( have required field validators ) .. I want to change their background color to yellow when they are left blank and when the box is filled the backgorund color to white ..Is it possible to do via javascript ..I am a beginer so any help is greatly appreciated How do I change a text input's background when the user hits "Enter" or Key #13. The text-input field currently light's up to blue when hovered over, then it turns green when it is focused on, and now I want it to turn pink when you submit it. (This can be seen at http://ocmd.co.nr/ap) ------------------ Also, if anyone knows how I can redirect the user depending on there input, that'd be great. Regularly, it just runs a Google Search, but if I could get it so that when someone typed in, "chat room 1" for example, it'd open up a link or a new window w/ that. Could anyone show me a script that would allow the user whos on my site change the background image from the default color to an image from a URL? And then it would have to save their choice in a cookie. Thanks!
Hi, i have a <td> with a background image and 3 other <td>'s that contains blank photos in them, i need 2 things that they'll make: 1. when i click on one td that contain blank image lets call it tdimg1 it will toggle the visibility of the div inside the first td lets call it tdframe and for the div lets call it divframe1, (i have a script that works) but the main issue is that when i click tdimg1 tdimg2 and tdimg3 it will show divframe1 divframe2 and divframe3 what i want is that it will show only one at a time, so if ill hit the tdimg2 it will show me divframe2 and if after that ill hit tdimg3 it will hide the divframe2 and appear the divframe3. 2.the tdframe have an image as a background lets call it basicbg.jpg, i want that when i will hit tdimg1 the background of the tdframe will change to lets say newbg1.jpg, and as ill hit it again it will go back to basicbg.jpg, as ill hit tdimg3 it will change to newbg3.jpg and if i wont "close" it and click tdimg2 it will just change it to newbg2.jpg thanks! I am wondering if it would be possible to add a Cookie to this code i found, i am wanting the browser to remember the chosen background image and save it when the user closes the browser. Currently when the option is selected it does not remember the choice when you then go back to the page, any help on this would be much appreciated! Many Thanks Code: <script type="text/javascript">
function changeTheme()
{
var e = document.getElementById("themes");
var theme = e.options[e.selectedIndex].value;
console.log(theme);
document.getElementById("shelf").style.backgroundImage = "url("+theme+")";
}
</script>
<body id="shelf"> <select id="themes" onChange="changeTheme()"> <option value="images/background1.jpg">Default</option> <option value="images/background2.jpg">Oriental</option> </select> Hi Complete novice with Java so need some help please! I want to put a button on a website that when clicked changes the background. The button needs to be an image. For example, click on the image and it makes the background image1 and then click again to switch to background image2. The image/button that is being clicked will be 2 images (one says "turn lights on" then when clicked shows other image "turn lights off") I have managed to pick up bits of code from the net that change the background and got another code that makes 2 images a toggle button. The button changes the background on the first click but no back again on the second click. I guess it needs an if/else statement but not sure. Thanks for any help!!!! 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"
onKeyDown="textCounter(document.myForm.message1,document.myForm.remLen1,125)"
onKeyUp="textCounter(document.myForm.message1,document.myForm.remLen1,125)"></textarea>
<br>
<input readonly type="text" name="remLen1" size="3" maxlength="3" value="125">
characters left
<br>
<textarea name="message2" wrap="physical" cols="28" rows="5"
onKeyDown="textCounter(document.myForm.message2,document.myForm.remLen2,125)"
onKeyUp="textCounter(document.myForm.message2,document.myForm.remLen2,125)"></textarea>
<br>
<input readonly type="text" name="remLen2" size="3" maxlength="3" value="125">
characters left
<br>
<input type="Submit" name="Submit" value="Submit">
<br>
</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 I just cannot get the html to load for each linked button to the Iframe. If I remove the "onclick" command for the backround images, the links load to the Iframe. If I leave the "onclick" command in there only the background changes. So, I would assume there is a conflicting issue with loading the "a href" and the "onclick" commands together. Maybe I need to know how to do multiple "onclick" commands...suggestions?
