JavaScript - Need Script To Change The Color Of Region In A Image
Hi ,
I need one javascript, which is going to change the color of the region in the particular image. For example one boy wearing the blue color t-shirts, i want to change the blue color into red color by using the color code instead of chaging the image into new one. Whether is this possible to do in javascript ? Any help greatly appreciated. Thanks, Suresh.k Similar TutorialsHi all, I have a free script I have downloaded and I can't figure out how to edit it so that I can change the color of the text to whatever I want it to be and also so that the length of the scrolling text (I am not sure if scrolling is the right term) can be changed. For some reason the text does not go all the way to the end of the page on the right it stops quite a way before. Here is the code: Code: <script language="JavaScript1.2">

//Secify scroller contents
var line=new Array()

line[2]="Always testing always testing"
line[3]="Trying to test some more and some more again"
line[4]="second to last bit of testing."
line[5]="Testing text that is just testing one more time"

var ts_fontsize="13px"

var longestmessage=1
for (i=2;i<line.length;i++){

I have been trying to figure this out for about 2 hours but since I am a 100% novice with javascript I have not got very far. Any help would be gratefully recieved. 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 I don't know if this is possible, so I figured I'd ask a few gurus. I know it is possible to have an image change at a certain time of day, and it's also possible to have an image change by day, but is there a script to do both? What I want to do is have the first image show from 8am cst to 6pm cst mon-fri, it's our open sign for live chat. The the rest of the time have the second image. Is this possible with any type of script? Any help you can give is greatly appreciated! <script language="JavaScript"> function changeColor(cell_id){var state1="#dde6ed"; var state2="#ffc20e"; var cellid = new Array ("id1", "id2", "id3", "id4", "id5", "id6"); for(var i = 0; i < cellid.length; i++){var nav = document.getElementById(cellid[i]); if(cellid == nav.id){nav.style.backgroundColor=state2;} else {nav.style.backgroundColor=state1;}}} </script> Can anyone tell me what is wrong with this script. I put an onClick= changeColor(this);" in my <td> tag to call the script but still not working. 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 ? 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 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 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 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.
