JavaScript - Change Color Of Every Other Row
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? Similar TutorialsHi! 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 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 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 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. 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 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 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 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 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 im trying to figure out a script that when someone clicks my checkbox (or onchange/onclick events the span tag that wraps it) it changes the color of the font in the span tag... but then if they click again...for the color to return to normal heres my checkboxes as of the moment... disregard the sloppy multiple classes....i wanted to pad the elements evenly lol Code: <div id="selectform">

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. 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> Hello all, Can anyone help me with a script for changing font color of a number within a table when there is a match? Table A contains numbers and table B contains numbers. When table B numbers matches some of the numbers in table A, the numbers in table A need to change color. I hope you understand what I mean. 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;
}
Okay I have searched google for hours literally without luck so hopefully someone here can help. What I am trying to do is when someone submits the form if there are empty textboxes change the textbox's style from class="input" to class="inputreq". Someone please help, the formname is "signup" and the textboxes are "domain" and "username". Please help. Thanks. Hi, I am stumped. I have been trying unsuccesfully for three days to figure something out, and it has brought me here. I am a noob javascripter, so please bear with me. I have created a page with an input button that refers to a function: Code:

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. Easier to show than to explain: Code:
<head>
<SCRIPT LANGUAGE="JavaScript">
function checkAll(field) { for (i = 0; i < field.length; i++) field[i].checked = true ; }
function uncheckAll(field) { for (i = 0; i < field.length; i++) field[i].checked = false ; }
</script>
</head>
<body>
<form name="myform">
<table>
<tr id="CA" name="list" value="1" style="background-color:yellow;"> <td> <input type="checkbox" name="list" value="1" onclick="document.getElementById('CA').style.backgroundColor=this.checked?'white':'cyan';">Choice CA</td> </tr>
<tr id="CB" name="list" value="1" style="background-color:yellow;"> <td> <input type="checkbox" name="list" value="1" onclick="document.getElementById('CB').style.backgroundColor=this.checked?'white':'cyan';">Choice CB</td> </tr>
<tr id="CC" name="list" value="1" style="background-color:yellow;"> <td> <input type="checkbox" name="list" value="1" onclick="document.getElementById('CC').style.backgroundColor=this.checked?'white':'cyan';">Choice CB</td> </tr>
</table>
<input type="button" name="CheckAll" value="Check All" onClick="checkAll(document.myform.list)">
<input type="button" name="UnCheckAll" value="Uncheck All" onClick="uncheckAll(document.myform.list)">
</form>
<p>All never touched should be yellow. All checked should have white background. All unchecked should have cyan background.</p>
<p>How do I get 'Check All' and 'Uncheck All' to obey the tr background color, too?</p>
I want to change the color of the gridview when a button which has the value of the row index of the gridview is clicked ...this button is not inside the gridview but some where else on the form but it can send the gridview rowindex to the function so need a function to change the color of the row or bring it to focus in someway... |
