JavaScript - How To Set Background-color On Page Load When Using Iframes
I've tried the following:
Code: <script type="text/javascript" language="javascript" charset="utf-8">
// <![CDATA[
if ( top.location.href!= window.location.href ) {
document.getElementById( 'bodybg' ).style.background='#12111C';
}
// ]]>
</script>
and Code: <script type="text/javascript" language="javascript" charset="utf-8">
// <![CDATA[
if ( top.location == location ) {
document.getElementById( 'bodybg' ).style.background='#12111C';
}
// ]]>
</script>
I've tested the if statement and the set background code, using a button. I'm guessing it fails since there is no background when the script runs. Any ideas? Similar TutorialsHi, I created a simple menu: Code: <html>
<head>
<style type="text/css">
table {width:400px;height:35px;border-collapse:collapse;border:1px solid #000}
td {text-align:center;padding:3px;cursor:pointer;font:bold 12px Verdana;color:#FFFFFF;background-color:#555}
</style>
</head>
<body>
<table border="1" bordercolor="#000">
<tbody>
<tr>
<td onClick="parent.location='home.htm'" onMouseover="this.style.backgroundColor='#000'" onMouseout="this.style.backgroundColor='#555'">Home</td>
<td onClick="parent.location='news.htm'" onMouseover="this.style.backgroundColor='#000'" onMouseout="this.style.backgroundColor='#555'">News</td>
<td onClick="parent.location='articles.htm'" onMouseover="this.style.backgroundColor='#000'" onMouseout="this.style.backgroundColor='#555'">Articles</td>
</tr>
</tbody>
</table>
</body>

Was wondering if you knew of a way to keep the button on the mouse-over style for as long as a user is on the page they clicked. This would mean that if a user clicked on a page named 'News', the 'News' button would stay in the mous-over style to indicate which page they were on. Regards Rain Lover Hi, As you will see with the code below when the text ONE and TWO are clicked on it displays a background color. When ONE is activated TWO is off. When TWO is activated ONE is off. But when the page loads I want ONE to display the background color. When ONE displays the background color after the page has loaded, I want to click on TWO to display it's background color and ONE should turn off as it does now. I can't figure out how to activate the background color for ONE when the page loads. Then if it is activated when the page loads, how to turn off ONE and turn on TWO when clicked on and visa versa.

Hi, I'm faced with a problem trying to set background color under IE7. I have the following Javascript: Code: function showLayer793BKColor(id)
{
var txtObj = document.all(id);
if (txtObj.style.display == 'none')
{
txtObj.style.display = ''
txtObj.style.backgroundColor = 'grey';
}
}
function hideLayer793BKColor(id)
{
var txtObj = document.all(id);
if ( txtObj.style.backgroundColor == 'grey' )
txtObj.style.display = 'none';
}
These functions are used to show or hide div blocks. These blocks are, for example, specified in the following way: Code: <div id="l_gct5tekst" style="display:none"> <b>GCT 5. Eerste verkenning problematiek</b> and, for example, Code: <div id="l_Keuze" style="display:none"> <br/> <b>GCT 5</b> <br/> </div> The whole configuration works smoothly when using IE8. However, when using IE7 I get an error msg like "Invalid value for property". When I use the Color propert iso the BackgroundColor property I get no error anymore but of course I don't have a background color anymore then. In what way can I specify the use of a background color under IE7 ? Or is just not possible in one way or the other. Furthermore, what more differences between JS under IE7 and IE8 do I have to take into account ? Do I also have to rewrite my div block in some way (using some attribs ?) to cope with IE7 ? Thanks in advance, Diederick van Elst Hi! New to JS... 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. Would be hugely grateful for any help, thanks so much in advance. (demo link of script in current state at bottom) Code: <html><head><title></title>
<script language=javascript>
colors = ["#cacdca", "#b2b4b2", "#969896", "#7d7f7d", "#ffff00"];
cRGB = [];
function toRGB(color){
var rgb = "rgb(" + parseInt(color.substring(1,3), 16) + ", " + parseInt(color.substring(3,5), 16) + ", " + parseInt(color.substring(5,7), 16) + ")";
return rgb;
}
for(var i=0; i<colors.length; i++){
cRGB[i] = toRGB(colors[i]);
}
function changeColor(target){
var swapper = navigator.appVersion.indexOf("MSIE")!=-1 ? toRGB(document.getElementById(target).style.backgroundColor) : document.getElementById(target).style.backgroundColor;
var set = false;
var xx;
for(var i=0; i<cRGB.length; i++){
if(swapper == cRGB[i]){
if(((i+1)) >= cRGB.length){
xx = 0;
}else{
xx = i+1;
}
document.getElementById(target).style.backgroundColor = colors[xx];
document.getElementById(target).style.backgroundImage.show;
set = true;
i=cRGB.length;
}
}
set ? null : document.getElementById(target).style.backgroundColor = colors[1];
}

Demo: http://theclutch.com/rollover_color_..._bgndimage.htm Hi all Is there a way to get the image(s) to load into the table after the page has loaded instead of the way I have it now? I have 4 tabs, but I would like the imgs in tabs 2,3,4 to load after page load. Example of how the tabs look. Code: <div class="tabbertab">
<h2>Australia_____</h2>
<table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFCC">
<caption class="highlight_Red">澳洲 Australia
</caption>
<tr>
<td><a href="pages/promotion.html#aus_ACE" rel="nofollow" target="_blank"><img src="pages/images/Pics/AUS/ace.jpg" alt="ACE / ATTC" width="110" height="69" border="0" align="left" class="ozimg_L"/> ...a few more images etc
the other tabs look the same. LT This script displays a link to a registration/login form that loads in a light box for Joomla. I've been goin nuts trying to figure out how to get this to load on page load with a delay. Anyone know how to get this done? PHP Code: <?php JHTML::_('behavior.mootools'); $document = JFactory::getDocument(); $document->addStyleSheet(JURI::base() . 'media/system/css/modal.css'); $document->addScript(JURI::base() . 'media/system/js/modal.js'); $document->addScriptDeclaration("window.addEvent('domready', function() {SqueezeBox.initialize({});});"); $user = & JFactory::getUser(); $uri = JFactory::getURI(); $url = $uri->toString(); $return = base64_encode($url); ?> <div id="lbframeid" style="position:absolute;top:1px;left:1px;height:0px;width:0px;overflow:hidden"> <a href="http://www.wowjoomla.com/"><h1>Joomla Login LightBox powered by WowJoomla.com</h1> </a> </div> <?php if ($user->get('guest')) :?> <a href="<?php echo JRoute::_('index.php?option=com_loginbox')?>" onclick="SqueezeBox.fromElement(this); return false;" rel="{handler: 'iframe', size: {x: 660, y: 500}}"><?php echo JText::_('SIGNUP_LOGIN')?></a> <?php else: ?> <?php echo JText::sprintf( 'HINAME', $user->get('name') ); ?> <br> <a href="javascript:void(0);" onclick="LB_onLogout(); return false;"><?php echo JText::_('LOGOUT')?></a> <?php endif; ?> <script type="text/javascript"> function LB_onLogout() { var form = new Element('form'); form.setProperty('method', 'POST'); form.setProperty('target', '_self'); form.setProperty('action', 'index.php'); var input = new Element('input'); input.setProperty('type', 'hidden'); input.setProperty('name', 'option'); input.setProperty('value', 'com_user'); form.appendChild(input); var input = new Element('input'); input.setProperty('type', 'hidden'); input.setProperty('name', 'task'); input.setProperty('value', 'logout'); form.appendChild(input); var input = new Element('input'); input.setProperty('type', 'hidden'); input.setProperty('name', 'return'); input.setProperty('value', '<?php echo $return; ?>'); form.appendChild(input); $E('body').appendChild(form); form.submit(); } </script> Hi, ok i been playing around with this for awhile now http://www.dynamicdrive.com/dynamici...iframessi2.htm could not get it to work, so i tried several others and still nada, i finally ran across http://www.codingforums.com/archive/.../t-224293.html and i worked with what old pendent had done. The result is that i got some good results, closer to what i wanted but i need to do it multiple times. It works for one but not the other. i thought about putting each iframe on a sep html page and then using two sep tables and doing a SS include. but there has to be a better way. what im doing is i have an amazon iframe and a shopzilla iframe for the same product search and i want them posted one under the other iframe iframe and expand as the size needs, alowing for either to be longer or shorter when needed. i can do one but i have not found a way to do both yet. i removed my code because it showed my personal affiliate info in the code, since i cant give you an example without showing the code i guess ill just use the auto scroll and live with it... thanks I have a website, the main page of which we'll call Parent_page. Within Parent_page there's an iFrame, the name of which is the_iframe. The default source of the_iframe is a page which is default.html. I want to supply people with a URL that: Step 1) Opens Parent_page displaying a source in the_iframe that is NOT default.html (that different source will be called different.html) Step 2) Then -- and this is the troublesome part -- does a page jump to element #12345 within different.html. I've managed Step 1. Here's the Javascript I'm using in the head of Parent_page to allow for Step 1 to happen: <script type="text/javascript"> function loadframe(){ if(window.location.replace) window.frames.the_iframe.location.replace(get('framepage')); else window.frames.the_iframe.location.href=get('framepage'); } function get(key_str) { var query = window.location.search.substr(1); var pairs = query.split("?"); for(var i = 0; i < pairs.length; i++) { var pair = pairs[i].split("="); if(unescape(pair[0]) == key_str) return unescape(pair[1]); } return null; } if (location.search&&get('framepage')!=null) if ( typeof window.addEventListener != "undefined" ) window.addEventListener( "load", loadframe, false ); else if ( typeof window.attachEvent != "undefined" ) window.attachEvent( "onload", loadframe ); else { if ( window.onload != null ) { var oldOnload = window.onload; window.onload = function ( e ) { oldOnload( e ); loadframe(); }; } else window.onload = loadframe; } </script> ...and here's the URL I use that opens different.html in the_iframe instead of default.html: mywebpage.com/parent_page.html?framepage=/different.html Again, that part works just fine. However, to accomplish Step 2, I thought I could just use: mywebpage.com/parent_page.html?framepage=/different.html#12345 But when I do that, suddenly nothing after the ? in the URL works. How can I make this page jump happen? Please, please dumb down your answers! I know HTML decently enough, but I don't know anything, whatsoever, about Javascript. The JS code above I copied from another website. Thanks! Hello, Can anyone figure out whats going on with this page and i need to finish the site by this evening? It is a wordpress site. the background image is shifting to the right on IE7 after the page loads on only the homepage. I think its the slider but im not sure www.grapevineoutreach.org thanks Hey, been racking my brain for about an hour now, and cant seem to work this one out... I need to in javascript, get the HEX value (#FFFFFF) of a div's background color... Code: style.backgroundColor doesnt seem to work... But it seems to be different in every browser, and i cant seem to make it work... (it must work in IE, FF, Chrome, Safari) I have tried using a couple of examples, but nothing seems to work... Any ideas? Thanks Hi! all I have a js which change the background color onclick event. This is the code Code: function changeBackground2() {
document.body.style.backgroundColor = '#C6DB2B';
document.getElementById("logo").style.backgroundColor = '#2299EE';
document.getElementById("nav_bar").style.backgroundColor = '#C6DB2B';
document.getElementById("current-ex3").style.backgroundColor = '#2299EE';
document.getElementById("foot").style.backgroundColor = '#2299EE';
document.getElementById("ahead").style.backgroundColor = '#C6DB2B';
}
but i want it to occur slowly like in 3 seconds. I think it can be done with animate but not know how i am not a js expert. Thanks for your help. Hi, I have the following javascript codes. I have two textboxes with id "pano" and "pano2" My function creates numbers randomly and that if random number==1 let the background of textbox2 be pink and if random number==2 textbox1 be red. The code works fine for document.bgColor but it does not work for textboxes how can I modify the code so that I can change the background color of any textboxes ? thanks.. <script> aaa=setInterval("letsgo()",500); function letsgo() { rno=Math.floor(Math.random()*3)+1; document.getElementById("counter").value=rno; if(rno==3) { document.bgColor="green"; } if(rno==2) { var pano=document.getElementById("pano"); document.pano.bgColor="red"; } if(rno==1) { var pano2=document.getElementById("pano2"); document.pano2.bgColor="pink"; } } </script> <input type="text" id="counter" style="position:absolute;top:10px;left:50px;width:60px;height:20px;"> <input type="text" id="pano" style="position:absolute;top:100px;left:100px;width:200px;height:200px;"> <input type="text" id="pano2" style="position:absolute;top:100px;left:400px;width:200px;height:200px;"> Hello. My goal is to load the JS for a specific element before displaying that element. I integrated a third part script, and it works well. I set the timer he The JS is in my heading as <script type="text/javascript" src="countdownpro.js"></script> About mid-body I have: <span id="countdown1">2010-07-20 00:00:00 GMT+00:00</span> which allows for the setting of a target date to countdown to. When the page first loads it shows the above long format target time, until the js/meta tags kick in to modify it to just show the actual countdown as 00:00:00. I have attached countdownpro.js to this post. I tried shifting the function CD_Init() to the top of the script, and also appended it inline with the .html. I tried setting the big external script to "defer", but neither arrangement worked. I also tried placing the src file right at the top. I appreciate your help. 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? Clearly I'm doing something wrong. Here's my external javascript: Code: document.getElementById('maincontent').style.backgroundColor = "#660000";
Here's my external CSS Code: #maincontent {
background-color: #999;
}
Here's my HTML: Code: <div id="container">
<div id="maincontent">
<p>blah blah blah</p>
</div>
</div>
Nothing happens. What am I doing wrong? Hey everyone! My goal here is to have the user type in a color and have that color display as the background of the page. I don't believe the switch statement is being executed by the first function. I think I am overthinking the process - as always! Any help pointing out my mistake(s) would be greatly appreciated. Code:
function show_color()
{
var show_prompt = prompt("Please enter a color name");
var change_body = document.getElementById("body");;
show_prompt = change_body;
change_body = change(this.id);
}
function change(id)
{
switch (id)
{
case 'red':
document.body.bgColor = "red";
break;
case 'green':
document.body.bgColor = "green";
break;
case 'yellow':
document.body.bgColor = "yellow";
break;
case 'blue':
document.body.bgColor = "blue";
break;
case 'pink':
document.body.bgColor = "pink";
break;
}
}
Can this be done? Change background color a row of depending on cell data on that row. e.g Items <table border="1"> <tr> <td><b>Cost</b></td> <td><b>Item</b></td> </tr> <tr> <td>12</td> <td>hats</td> </tr> <tr> <td>34</td> <td>socks</td> </tr> <tr> <td>12</td> <td>hats</td> </tr> <tr> <td>12</td> <td>hats</td> </tr> <tr> <td>24</td> <td>gloves</td> </tr> </table> Any pointers in the right direction please I have a table row that I would like to have change color when onMouseOver, and revert back onMouseOut. That works fine. Now, I have added an onClick event, which when they click I want the color to stay. Here is what I have. It works, sort of, that is it changes only the first row and not the one I clicked. How do I refer to the row that is clicked? Thanks! Code: <script type="text/javascript">
function check(x)
{
document.getElementById("rowColor").bgColor=x
}
</script>
<tr id="rowColor" onClick="check('#99FF99');" onMouseOver="this.bgColor='#99FF99';" onMouseOut="this.bgColor='#FFFFFF';"><div>
Hi All, Im new to this forum...need some of your help and advice. I have a js code like this : <script type="text/javascript"> <!-- var sipPos = 0; $(document).ready(function() { $("#panel-tab").click(function(e) { //if(autoTimer) clearTimeout(autoTimer); //autoTimer = null; e.preventDefault(); $("#panel").animate({ left: sipPos }, 1764, 'linear', function() { if(sipPos == 0) { sipPos = -856; } else { sipPos = 0; } }); }); }); --> </script> what it does is that it hide and show a panel by slidint it to the left. But my client want that on page load the panel opens automatically for about 2-3 seconds just to let users know that its here. So ive written this : <script type="text/javascript"> <!-- var sipPos = 0; $(document).ready(function() { var autoTimer = null; autoTimer = setTimeout(function(){ $("#panel").animate({ left: sipPos }); autoTimer = setTimeout(function(){ $("#panel").animate({ left: sipPos = -856 }); }, 2000); },1000); $("#panel-tab").click(function(e) { //if(autoTimer) clearTimeout(autoTimer); //autoTimer = null; e.preventDefault(); $("#panel").animate({ left: sipPos }, 1764, 'linear', function() { if(sipPos == 0) { sipPos = -856; } else { sipPos = 0; } }); }); }); --> </script> But when the panel finished showing the button to open it again doesn't work...any help please..really urgent. thks //Sam I want to create a basic script where someone clicks the button and the document color is changing. while I can do it with inline even handlers and also using the script block in html document, i am not able to achieve the result using the external js.js. My goal is not to use any even handlers at all inside the html document. This is how my codes looks like: <head> <title> Basics Exercise</title> <script type="text/javascript" src="js.js"></script> </head> <body> <form> <p> Click this button and the document's color will change again </p> <input name="button" type="button" value="Change the background color of the document"/> </form> js.js has function changecolor() { document.bgColor='#ea0d17'; } document.forms[0].button.onClick=changecolor(); I don't want anyone to write a script for me, but I would appreciate if someone told me why the script I wrote is not working. |
