JavaScript - Javascript Color Changing Code...how Is This Done?
Hey guys,
I have been trying to get better at my javascript as of late and there is this one particular color fading technique I have found that I am having trouble dissecting. The following code appears to be how they are making a rollover go from a dark gray to a subtle light gray with a nice fade but I can't exactly tell whats going on from the code. Is it just telling it to add a rgb point in so many seconds? Any professional help would be greatly appreciated. Code: colorInit=
true}b.elem.style[a]="rgb("+Math.max(Math.min(parseInt(b.pos*(b.end[0]-b.start[0])+b.start[0],0),255),0)+","+Math.max(Math.min(parseInt(b.pos*(b.end[1]-b.start[1])+b.start[1],10),255),0)+","+Math.max(Math.min(parseInt(b.pos*(b.end[2]-b.start[2])+b.start[2],0),255),0)+")"}});
Similar TutorialsI am very new to coding, trying to teach myself some javascript. I know this is a very simple code, I just can't seem to nail down what is going wrong. Feeling really stupid right now. Heres the code: Code: <html>
<head>
<script language="JavaScript">
var choice=confirm("Press ok for black. Press cancel for red.");
if (choice==true){
document.bgColor="yellow";
document.fgColor="black";
}
else {
document.bgColor="red";
document.fgColor="white";
}

If someone could take a second to set me straight, I would really appreciate it. btw: hope I posted all this according to the "rules". I tried Hi sorry if this is a very simple question but how do I change the font color for certain elements of this javascript code that the client sees on their brower? This is a count down script and I have made the code red that I am trying to change - any idea how to do this? Thanks v much!!!! <script type="text/javascript"> var today=new Date() //Enter the occasion's MONTH (1-12) and DAY (1-31): var theoccasion=new Date(today.getFullYear(), 03, 21) //Customize text to show before and on occasion. Follow grammer below: var beforeOccasionText="until this event" var onOccasiontext="Event is Today!" var monthtext=new Array("Jan","Feb","Mar","April","May","June","July","Aug","Sep","Oct","Nov","Dec") theoccasion.setMonth(theoccasion.getMonth()-1) //change to 0-11 month format var showdate="("+monthtext[theoccasion.getMonth()]+" "+theoccasion.getDate()+")" //show date of occasion var one_day=1000*60*60*24 var calculatediff="" calculatediff=Math.ceil((theoccasion.getTime()-today.getTime())/(one_day)) if (calculatediff<0){ //if bday already passed var nextyeartoday=new Date() nextyeartoday.setFullYear(today.getFullYear()+1) calculatediff=Math.ceil((nextyeartoday.getTime()-today.getTime())/(one_day)+calculatediff) } //Display message accordingly var pluraldayornot=(calculatediff==1)? "day" : "days" if (calculatediff>0) document.write("<b>"+calculatediff+" "+pluraldayornot+" "+beforeOccasionText+" "+showdate+"</b>") else if (calculatediff==0) document.write("<b>"+onOccasiontext+" "+showdate+"!</b>") </script> So my functions are dealing with Time. The function delay_time() is called by clicking a button in html and the return value of the function is displayed in a textbox. What I need to do is basically if the value of resultingtime is greater that the value of delay time I need the value shown in red(ff0000) and bold and if it isnt then I need it displayed in bold green(00ff00). but Ive tried doing this in my javascript and found that I cant code it in there the way that I know. I really dont know what to do... I think that I have to do it in the html coding but I dont know how. Here is the javascript I wrote: Code: function delay_time(idealTime, startTime, stopTime, delayTime) {
var delay_time = idealTime.value;
var bigger_time = stopTime.value;
var smaller_time = startTime.value;
var resultingtime = subtract_time(bigger_time, smaller_time, delay_time);
//if (resultingtime > delay_time) {
//resultingtime = resultingtime.fontcolor("ff2000");
//resultingtime = resultingtime.bold();
//}
//else {
//resultingtime = resultingtime.fontcolor("60ff00");
//resultingtime = resultingtime.bold();
//}
delayTime.value = resultingtime;
}
function subtract_time(bigger_time, smaller_time, delay_time) {
var bigger_value = convert_time_to_value(bigger_time);
var smaller_value = convert_time_to_value(smaller_time);
var idealTime = delay_time;
var resultingtime = bigger_value - smaller_value;
return resultingtime;
}
function convert_time_to_value(time_format) {
var hh = time_format.substring(0, 2);
var mm = time_format.substring(3, 5);
var time_value = (eval(hh) * 60) + (eval(mm) * 1);
return time_value;
}
and here is the html code for the button : Code: ID="Button15" type="button" value="Delay Time"
onclick="delay_time(document.getElementById('TextBox102'), document.getElementById('TextBox104'), document.getElementById('TextBox105'), document.getElementById('TextBox106'))"/>
here is the text box I have the value going into: Code: <asp:TextBox ID="TextBox106" runat="server" Height="0.25in" Style="font-family: Arial, Helvetica, sans-serif;
font-size: medium" Width="0.75in" BorderStyle="Inset"></asp:TextBox>
and here is the code from the box that I need to know if the value is bigger or smaller than: Code: <asp:TextBox ID="TextBox102" runat="server" Height="0.25in" Style="font-family: Arial, Helvetica, sans-serif;
font-size: medium; text-align: right;" Width="0.5in" BorderStyle="Inset"></asp:TextBox>
please help. 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;
}
}
Hello, I can't seem, for the life of me to get this to work at all. I've tried everything out there and can't get it to work with IE 7: I would like to change the border color of my table row on hover. Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

I desperately need your help before I have no hair left. Thanks for all your help in advance, Cheers, J hi im trying to make the background color change to white after the iframe is triggered. right now it sits transparent on the page but after the iframe is triggered i want the background to be white. is there a way to do this? i dont know much about java but im assuming this would be something to use java for. Thanks Code: <iframe name="result" style="border: 0px solid #000000;"frameborder="0" width='100%' height='590px' src="result1.php" allowtransparency="true"></iframe> I'm a member of a forum the for the Winter season has changed it's CSS a:link color attribute to a more winter themed colour. However I want to revert back to original as I don't particularly like the new colour. My theory is to create a small JS file, that I can define Opera (my browser) to load when loading the site, which will change the colour of links back to the original colour. I have the colour code HTML I want to change it to. I've only ever done a small amount of JS coding but from the research I've done it should go something like this, Code: document.style.alinkColor = "COLOR" I got to that via discovering that Code: document.style.backgroundColor = "COLOR" will change the background colour attribute, however it doesn't seem to work. I think my problem lies somewhere in the attribute name, I know the usually with JS CSS Attributes you would make the attribute starting with a lower case letter and the sub-attribute (e.g. the color bit) starting with an upper case. Anyone able to point me in the right direction? Hello I want to html text to show diffrent color, if date in list is in the past. shoud this even work ? am i hopeless? Code: <script type="text/javascript">
var day = d.getDay();
var event = this.document.getElementById('list');
if ('day' < 'event')
{
document.getElementById('list').style.color = '#DB35B0'
}
</script>
<ul>
<li id ="list">26/02/12 Some happening here</li>

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. 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 Is it possible to give an anchor tag an id and call it with GetElement? this is what I have tried: Code: <a id="link1" href="test.html">Part 1</a></li> Code: document.getElementById("link1").style.color = "blue";
This is my CSS: Code: A:link {
color:#ffffff;
font-size:14pt;
font-weight:bold;}
A:visited {
color:#ffff00;
font-size:14pt;
font-weight:bold;}
A:hover {
color:#6698ff;
font-size:14pt;
font-weight:bold;}
A:active {
color:#c0c0c0;
font-size:14pt;
font-weight:bold;}
Hi all, I currently have this javascript that will change the cell to green with one click... Code: <script type="text/javascript">
function ColorChange(obj){
obj.style.color='#FFFFFF';
obj.style.backgroundColor='#66CC33';
obj.parentNode.style.backgroundColor='#66CC33';
}
</script>
echo "<td align=\"center\" bgcolor=\"#EEEEEE\"><a href=\"#\" onclick=\"ColorChange(this)\">$day_num</a></td>";
the problem is that I need around 3 different colors to be possible.. e.g. 1 click turns cell green | 2 turns is red | 3 turns it orange. I'm not sure how to take this javascript further? Would someone be kind enough to point me in the right direction? Many thanks, Greens85 OK. I'm super new to any kind of java script. What I want is a menu that, when clicked, changes the background color of a table cell to blue. When a different option is clicked, the current highlighted table should turn back to gray and the new selection should be blue. Well, I have all of that working. What I need now is just to have the first option start out highlighted and to become unhighlighted when another option is clicked. Any help would be awesome!!!! Thanks!!!!!! Code: <html>
<head><title>menu</title>
<script type="text/javascript">
var element = null;
function select(xx)
{
if ( element ) {
element.style.backgroundColor='gray';
}
element = xx;
xx.style.backgroundColor='navy';
}
</script>
<style type="text/css">
a {text-decoration:none; color:white}
a:visited {color:white}
a:active {color:white}
a:hover {color:white}
table#lay_menu {width:100%; margin:0px}
table#lay_menu td {text-align:center; width:20%}
.menu {text-align:center; background-color:gray; }
.start {text-align:center; background-color:navy; }

I am building an online survey using a survey creation tool which allows me to incorporate javascript for additional functionality. However, I am new to javascript so would appreciate any help that you could provide me with. I have question types like agreement scales, where the respondent sees a list of statements and has to rate each one by clicking on a radio button.

However, the survey tool has a "JavaScript Editor" for each question, where I can put in javascript functions, and it executes them when the page loads. What I want to do is to have the label for each row (i.e for each statement) to change color when a corresponding radio button has been selected. This way, it is easier for respondents to see which rows they have answered. I used the following JS code: Code: var radioname = [];
var radiolist = [];
var labelspans = [];
var labels = [];
var radios = [];
var count;
var spans = document.getElementsByTagName('span');
function getLabels()
{
for (x=0; x<spans.length; x++)
{
if (spans[x].className == "LabelWrapper")
{
labelspans.push(spans[x]);
}
}
for (y=0; y<labelspans.length; y++)
{
labels.push(labelspans[y].firstChild);
radioname.push(labelspans[y].firstChild.htmlFor);
}
}
function getRadios()
{
//will put all radio groups into the "radiolist" array
for (z=0; z<radioname.length; z++)
{
radiolist.push(document.getElementsByName(radioname[z]));
//will add Event Listener to each radio button, and add each one to the "radios" array
for (i=0; i<radiolist[z].length; i++)
{
chkradio = radiolist[z][i];
chkradio.setAttribute("count",Number(z));
chkradio.addEventListener("click", function(){changeLabel()}, false);
radios.push(chkradio);
}
}
}
function changeLabel()
//loops through all the radios to check if they are selected, and changes label color accordingly
{
for (w=0; w<radios.length; w++)
{
if (radios[w].checked)
{
a = radios[w].getAttribute("count");
labels[a].innerHTML = labels[a].innerHTML.fontcolor("green");
}
}
}
getLabels();
getRadios();
This code works as intended; however, as you can see, it loops through all the radio buttons when one is clicked. Is there a way to accomplish this without looping through all the radios, and thus make the script run faster? Also, I have read that the addEventListener function does not work for older versions of IE. Is there a simpler alternative? HI every one i want to disallow users to change a text input values .

That produces this: I want to get rid of that strip on the bottom that says "Get This" which stretches all the way across. Is there anything I can change in that code to make this happen? I work at a college radio station and our brand new website just went live, but we're having one particular issue... We have a set list of shows that air each day, and on the site we have a marquee tag on the homepage that scrolls through showing each show and its broadcast time. Right now we're stuck changing this schedule each day by hand, but it's tough considering we're all college students ourselves and sometimes our own schedules simply don't allow the time. Is there a code that would allow this kind of a daily update to happen automatically? The format for the schedule is such: 4 - 5 pm // "Show 01" 5 - 6 pm // "Show 02" 6 - 8 pm // "Show 03" 8 - 10 pm // "Show 04" 10 - 12 am // "Show 05" Any help would be very much appreciated! hi i am totally frustrated !! i have been using this on my webpage. http://www.barelyfitz.com/projects/tabber/ if u see under the advanced section there is a code for changing tabs dynamically. Code: document.getElementById('mytab1').tabber.tabShow(0);
this doesn't work. basically i have a webpage internet.htm. which has a menubar with loads of menu items. if i click one of the submenu items this code should change the dynamic tabs in admin.htm. the code i have defined for the submenu click is: Code: <li><a href="admin.htm" onClick="document.getElementById('Admin').tabber.tabShow(0)" >Forms</a></li>
the full code is: Code: <ul id="QualityMenuBar" class="MenuBarHorizontal">
<li><a class="MenuBarItemSubmenu" href="#"><strong>Admin</strong></a>
<ul>
<li><a href="AdminDocuments.htm" onClick="document.getElementById("Admin").tabber.tabShow(0)" >Forms</a></li>

<li><a href="AdminDocuments.htm">Plans</a></li>
<li><a href="AdminDocuments.htm">Procedures</a></li>
</ul>
</li>
this is what the admindocuments.htm contains, based on the website link i have borrowed the code from. Code: <div class="tabber" id="admin">

whenever i click the submenu they all point to the first tab only. it doesn't change inspite of the code. what am i doing wrong here? please advice. Many thanks. Hello All. I'm trying to create a file upload page with pre-uploading preview, and using JS to change the images src upon selecting a local file. this works great, but unfortunatelly only for some image files, even though files were taken by the same camera,the same size, and created on the same date. I can't figure out for the life of me what is going on. The Code : <script> function changeImage(newSrc) var str = newSrc.toLowerCase(); cImg=document.getElementById("chngImg"); cImg.src=str; </script> <HTML> <BODY BGCOLOR="#FFFFFF"> <FORM METHOD="POST" ENCTYPE="multipart/form-data" ACTION="UploadScript1.asp" rel="nofollow" target="newWnd"> File 1:<INPUT TYPE=FILE NAME="FILE1" onchange="changeImage(this.value);"> <INPUT TYPE=SUBMIT VALUE="Upload!"> </FORM> <div><img src="oren1.jpg" id="chngImg"></div> </BODY> </HTML> Best Regards Oren Pildus Is it possible to use Javascript to dynamically change the PHP file used for an include? For example, if I have a php doc like Code: <html>
<body>
<div>other stuff</div>
<div>
<?php include('onefile.php'); ?>
</div>
<div>more other stuff</div>
</body>
</html>
I can get Javascript to remove the included stuff, but I can't figure out how to change the <?php include('onefile.php'); ?> into <?php include('otherfile.php'); ?>. What would be the best way to do that? |
