JavaScript - Additional Color Array For Background Color Change On Mouseover
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 Similar TutorialsHi, Am trying to change both, the background color and the mouse pointer to hand on the mouseover event. Am using this to change the background color: Code: onMouseover="this.bgColor='#55FF55'"onMouseout="this.bgColor='#AEFFAE'" How and i add the "change pointer to hand" on this as well? Thanks Hi, I want to make a piece of text fade from black to white while someone puts their mouse over it and change it back to black when they move their mouse away. I did it with the following code, but I'm wondering if anyone would do some (or all) of it a different way. Thanks! Code: //convert RGB values to hexidecimal
function RGBtoHex(color) {
var digits = /(.*?)rgb\((\d+), (\d+), (\d+)\)/.exec(color);
var R = parseInt(digits[2]);
var G = parseInt(digits[3]);
var B = parseInt(digits[4]);
Hex = new Array(R, G, B);
return Hex;
}
// Start the text fading
function FadeStart(id, FadeTo) {
Element = document.getElementById(id);
OriginalColor = getComputedStyle(Element, null).color;
Start = RGBtoHex(FadeTo);
rgb = RGBtoHex(OriginalColor);
red = (Start[0] - rgb[0])/16;
green = (Start[1] - rgb[1])/16;
blue = (Start[2] - rgb[2])/16;
BeginFading = true;
Fade();
}
//Actually do the fading
function Fade() {
var Complete = (BeginFading == true && rgb[0] != Start[0] && rgb[1] != Start[1] && rgb[2] != Start[2]);
if (BeginFading == true && rgb[0] != Start[0] && rgb[1] != Start[1] && rgb[2] != Start[2]) {
rgb[0] += red;
rgb[1] += green;
rgb[2] += blue;
var ChangeColor = "rgb(" + Math.round(rgb[0]) + ", " + Math.round(rgb[1]) + ", " + Math.round(rgb[2]) + ")";
Element.style.color = ChangeColor;
time = setTimeout("Fade()", 500);
}
}
//Return text to original color
function FadeStop() {
BeginFading = false;
clearTimeout(time);
if (Element != null) Element.style.color = OriginalColor;
}
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 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? 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 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 Hello, I am trying to change the background color of a table based on the value of a picklist. For instance. if the picklist value was "1", then the background color of the table should be red. Not sure where I went wrong in my code. Code: <html>
<body>
<script type="text/javascript">
if (level="1")
{
levelColor = #FF0000;
}
</script>
<select name="level">
<option value="1">1
<option value="2">2
<option value="3">3
<option value="4">4
<option value="5">5
</select>
<br><br>
<center>
<table name="levelColor" width="700px" height="100px" cellspacing="0" cellpadding="0" border="1">
<tr>
<td><center>This is the level.</center></td>
</tr>
</table>

Please help. Thank you. 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!

i would like to change certain style elements of the array each time the button is clicked. I have 5 color sets i would like use for the page, so i would like the button to trigger the color change in a loop, ie when the last color group is reached, the next click returns to the original color set and it continues again. This is a demo page, not for actually publication. I am trying to teach myself javascript and this is an idea that came to me. The things i want to change are the background color of two div's and the top row of a table. My style sheet is seperate, and I will also do the same for the javascript once I can get it to work properly. Thank you in advance for any help. I am using a great script i downloaded at http://kryogenix.org/code/browser/sorttable/ to sort tables by the header. my problem is I want to add to this that everyother row should have a gray background. I now do it by assigning a different class to every other row but when you sort it keeps the class. -- is there a way to change the background color of every other row in javascript that I can use with the above script? For Script http://www.dynamicdrive.com/dynamici...htmlticker.htm How do I change the "subject" color above each message from the default black to white ? I have a number var number = 1,235.326232 I need to display it like following with the last 4 numbers in red. 1,235.32 6232 I have tried number.slice(0,-4)+"<font color='red'>"+number.substr(number.length-5,4); however it keeps messing up the comma and decimal placement. Due to a long story which we don't need to go into here I am trying to change the color of a link after it has been clicked on WITHOUT using CSS. When the link is clicked some javascript is called. I can do this in IE by adding this "this.style.color = 'black'". However this doesn't work in other browsers. Anyone know how I could get this to work in other browsers? I've spend hours on this... Thanks for yuor time! Still need assistance, thanks Okay, so here's an example code of what I'm needing: Code: <html>
<head>
<title></title>
<style type="text/css">
#greenrow {
background-color:#090;
}
#redrow {
background-color:#F00;
}
</style>
<script type="text/javascript">
if (calculate.level.value >= calculate.getElementById('shrimp').value){
class = greenrow;
}
else {
class = redrow;
}
</script>
</head>
<body>
<form name="calculate">
<table>
<tr>
<td><label>
Level<input name="level" type="text" size="5" /></label>
</td>
</tr>
<tr id="shrimp">
<td>Shrimp</td>
<td align="center"><label>
<input type="text" name="shrimp" />
</label></td>
<td colspan="3" align="left">10</td>
</tr>
</table>
</form>
</body>
</html>
Okay so what I want to be done is to get information from the input text area "level" and IF "level" is >= 10...for this one certain row, I want it to get the class #greenrow. Else, class = #redrow. Thanks here is my problem i need to set the color of a text here is what i need to change Code: <div style="position:absolute; left:10px; top:100px; width:250px; text-align:center;"> <font color="lightgreen" size="6"><b>* Mileage *</b></font><b> <font color="black" size="6"><div id="bullet4">Not Specified</div></font><br></b> <font color="lightgreen" size="6"><b>* Gearbox *</b></font><b> <font color="black" size="6"><div id="bullet5">Not Specified</div></font><br></b> <font color="lightgreen" size="6"><b>* Engine size *</b></font><b> <font color="black" size="6"><div id="bullet6">Not Specified</div></font><br></b> <font color="lightgreen" size="6"><b>* Body style *</b></font><b> <font color="black" size="6"><div id="bullet7">Not Specified</div></font><br></b> </div> now i need to set the color from a text file server side so far i can set the contents of the div serverside but the customer needs to be able to change the color of the innerhtml . now i would like to store the color in a text file color.txt i can make the code to change the txt file myself inside the color.txt would be "lightgreen" or other color how would i go about this. so in basic terms i need to set the color of the text from a color.txt file sat next to the index.html I am trying to figure out how to change certain text's font color, in the text area. I have been looking everywhere, but I haven't found a solution. Any help would be great, thanks, mazzzzz Hi guys, Am creating a web page in which a user searches a customer using customer id. The results are then displayed in a table. This is working fine. In addition to this, I have created another form in which a user enters a value in a textbox. This value is then compared to the results obtained in the previous table.The values below should be shown in green and those above in red (identical values may be shown in amber). This should be acomplished using javascript. My code is as shown below: PHP 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"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Search Script</title> <script type="text/javascript"> function hallo(){ var value1=200 var inputVal = window.document.getElementById("one").value; //alert(negNum); if(inputVal > value1){ window.document.getElementById("color").style.color="red"; } else if(inputVal < value1) { window.document.getElementById("color").style.color="green"; } else if(inputVal == value1) { window.document.getElementById("color").style.color="#FF7E00"; } } </script> </head> <body> <form> Value1: <input type="text" name="one" id="one" ><br/> Value2: <input type="text" name="two" id="two" value="" onClick="hallo();"> <br/> Value3: <input type="text" name="three" id="$cell" value="test data"> </form> <?Php require_once("database.php"); $CustID=$_POST['CustomerID']; $query="SELECT c.*,r.Meter_No,r.January,r.February,r.March,r.April,r.May,r.June FROM customer AS c,readings AS r WHERE c.CustomerID=r.CustomerID AND c.CustomerID='".$CustID."'"; $result=mysql_query($query) ; //If no matching records are found in the database,the code below will display a customized error message $num=mysql_numrows($result)or die("No Matching Records Found In The Database!"); $fields_num = mysql_num_fields($result); echo "<h3>Historical Meter Readings</h3>"; echo "<table border='0'cellspacing='5' cellpadding='5' id ='three'><tr>"; // printing table headers for($i=0; $i<$fields_num; $i++) { $field = mysql_fetch_field($result); echo "<td >{$field->name}</td>"; } echo "</tr>\n"; // printing table rows while($row = mysql_fetch_row($result)) { echo "<tr id='color'>"; // $row is array... foreach( .. ) puts every element // of $row to $cell variable foreach($row as $cell) echo "<td align='center' <font face='Arial, Helvetica, sans-serif' >$cell</td>"; echo "</tr >\n"; } mysql_free_result($result); ?> </body> </html> Currently my javascript code changes the entire row in the table, which is not I desired. How do I edit this script so that only values in particular CELL in a row e.g CELL 5, is changed and not the entire row? Thank you. Hi not really used to java but have an image map with about 90 hotspots. All i want to do is simply change the color of a hotspot when the mouse rolls over. I have really only been able to find solutions for introducing images on mouse over. Any help appreciated thanks I want the font color in the div to change color onclick and change back when clicked again. Tjis works only in IE but other browsers like FF and safari it changes color on click but does not change color back. I need it to work across. Please advise! <div onclick="if(this.style.color=='#666666') this.style.color='#005dab'; else this.style.color='#666666';" class="question">Your question goes here..</div> |
