Plz help me. Thnx in advance Similar TutorialsI may be too close to this to see the answer but i have an image viewer with one big image and lots of little ones. What i need is that when you click on one of the smaller ones it grabs it's image src and sets the larger photo to that src. The small images are dynamic but the larger image will have a static id.
Hi, on my site, I have added Style 1 and Style 2 in my menu at the top right http://www.thisisworthing.com/default.php# when I click on Theme 2, it doesn't work?! please help! I have this working on my other site: http://www.mypubspace.com what am i doing wrong?! Hi, I am no very little when it comes to Javascript but I have seen a few sites using pre populated text boxes for login forms. So Username and password appears in the boxes to save space. The code below works fine onload of the site in all browsers, everything also works fine in firefox but ie the following doesn't seem to work. When a user clicks to enter their password in i.e. it doesn't change the form to password characters so input plain text. Also when you click out of either box it doesn't seem to re-populate the boxes with my Username or Password text. Any help would greatly be appreciated. Code: <script>
function HideLabel(txtField){
if(txtField.name=='myusername'){
if(txtField.value==txtField.defaultValue)
txtField.value = '';
else
txtField.select();
} else if(txtField.name=='mypassword'){
if(txtField.value==txtField.defaultValue){
txtField.value = '';
txtField.type = 'password';
}
else{
txtField.type = 'password';
txtField.select();
}
}
}
function ShowLabel(txtField){
if(txtField.name=='myusername'){
if(txtField.value.trim()=='')
txtField.value = txtField.defaultValue;
}else if(txtField.name=='mypassword'){
if(txtField.value.trim()==''){
txtField.value = txtField.defaultValue;
txtField.type = 'text';
}
}
}
</script>
<input type="text" name="myusername" id="myusername" onfocus="HideLabel(this)" onblur="ShowLabel(this)" style="border:0;" value="Username" />
<input type="test" name="mypassword" id="mypassword" value="Password" onfocus="HideLabel(this)" onblur="ShowLabel(this)" style="border:0;" />
Can someone tell me why this short script won't work? <script type="text/JavaScript"> <!-- function timedRefresh(timeoutPeriod) { var number = rand(7); if (number == 1) { var bgcss = "theme1.css"; } else if (number == 2) { var bgcss = "theme2.css"; } else if (number == 3) { var bgcss = "theme3.css"; } else if (number == 4) { var bgcss = "theme4.css"; } else if (number == 5) { var bgcss = "theme5.css"; } else if (number == 6) { var bgcss = "theme6.css"; } else if (number == 7) { var bgcss = "theme7.css"; } document.write('<link href="bgcss "'+ 'type=text/css rel=stylesheet>'); } // --> </script> </head> <body onload="JavaScript:timedRefresh(10000);"> Hi. I have a JavaScript that resizes an image held within an Iframe. It works perfectly, BUT only works if there is an alert box in the code. /*Image resizing scripts - Dependant on page size!*/ /////////////////////////////////// function Im_Resize() { var imheight = 550; /*Change the IFrame CSS*/ iframeheight = imheight + 15; /* +15px for the x-axis scroll bar*/ var IFrame = document.getElementById('MainFrame'); IFrame.style.height = iframeheight + 'px'; alert('after iframe size - before im change'); /*Change the Image CSS*/ var innerdoc = IFrame.contentDocument || IFrame.contentWindow.document; Image1 = innerdoc.getElementById('MainImg1'); Image1.style.height = imheight + 'px'; } If I take the alert box out the code just doesn't work?? I thought that it was that during the loading of the page an element hadn't been loaded yet, but a delay doesn't work either. If I press 'ok' on the alert box too quick it doesn't work either. In terms of HTML this script is run whenever the page is loaded and is also fired when a click event is detected on one of the divs on the page. Any help would be great Ed hey guys i downloaded the 'Content Slider v2.4', and this has a feature which will save a cookie used to remember and recall the last content viewed by the user when they return to the page. (click here for more information on the script.) the only thing is that this is made for pages with URLs such as: Quote: www.mysite.com/gallery_album_1/content.php but my URLS are set out like: Quote: www.mysite.com/content.php?gallery_album_1 is there a way to make to so the cookie remembers the page via the "php?gallery_album_1" part instead of the "content.php" part. i need it to be like this simply because i have multiple galleries coming from the oe page, eg: Quote: www.mysite.com/content.php?gallery_album_1 www.mysite.com/content.php?gallery_album_2 www.mysite.com/content.php?gallery_album_3 the main code of the js is as follows: Code: //** Featured Content Slider script- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com.
//** May 2nd, 08'- Script rewritten and updated to 2.0.
//** June 12th, 08'- Script updated to v 2.3, which adds the following features:
//1) Changed behavior of script to actually collapse the previous content when the active one is shown, instead of just tucking it underneath the later.
//2) Added setting to reveal a content either via "click" or "mouseover" of pagination links (default is former).
//3) Added public function for jumping to a particular slide within a Featured Content instance using an arbitrary link, for example.
//** July 11th, 08'- Script updated to v 2.4:
//1) Added ability to select a particular slide when the page first loads using a URL parameter (ie: mypage.htm?myslider=4 to select 4th slide in "myslider")
//2) Fixed bug where the first slide disappears when the mouse clicks or mouses over it when page first loads.

as far as i can see, the parts of the code which are about the cookies are labeled "enablepersist" thanks guys Hey, I'm working on a script that uses a function (called on click) to change the content of a div (called description) within the page. It contains an unordered list and list items. The first one has the class "show" and the ID "1", the second with just the ID "2", and so forth. (see code below). I am using jQuery to control the onclick function. the jQuery gets the current object with the "show" class. If there is no show class, it takes the first. It then puts a variable string together that represents the UL LI that is needed to be shown. Code: var descurrent = ($('div#description ul li.show')? $('div#description ul li.show') : $('div#description ul li:first'));
var desclass = '#description li#'+x;
Note: x is a variable transfered from the function change(x); where x is the ID that is to be shown HTML CODE: Code: <div id="description"> <ul> <li class="show" id="1">blahblah </li> <li id="2"> etc </li> </ul> The jQuery i'm trying to get to work is: Code: //Hide the current image
descurrent.animate({opacity: 0.0}, 1000)
.removeClass('show');
//Show new image
$(desclass).addClass('show')
.animate({opacity: 1.0}, 1000);
Note: the class "show" has a higer z-index Thanks in advance, Hope this can be resolved soon, been giving me headaches! Cheers, John Hi there. I'm relatively new to coding in javascript, so I'm hoping that some kind souls could help me out! I'm trying to make an animated image height changer (example: changing an image's height from 50px to 500px). I'm working on a new web site using HTML5 and want to add some Flash-like animation to my page using javascript and <canvas>. The animation would only need to "play" one time once the web page has loaded. No looping is required and no user interaction (ie mouseovers, etc) is needed. Any help would be greatly appreciated. If anyone knows of similar examples online please send me a link. If you're interested in helping, please let me know if more information is needed. Thanks. 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, 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 I'm going to try to explain this without sounding like a total idiot. I'm not even sure if this is the language for this. If not and someone could point me in the direction of a better language, please feel free. Lets say I have a word document, somthing.docx. This document includes text of varying colors. What I am trying to figure out is if there is a way of 'detecting' what color each word is. I would like the output be a txt file, which stores the text and description of formatting, which I can easily do myself. I really just have no idea how to figure out what color the text is, programmatically. Thanks for any help, ~Dave I am using an external style sheet to set the color of my calculator to gray. However, when I open my javascript in Google Chrome, the calculator is red. I've checked the style sheet code and it's correct. Can anyone tell me why this is happening?

Code: #div1 {color:#999999}
#div2 {color:#999999}
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. Hello everyone, I have written a color tween script based off of istallkizza's script that he provided for someone else in a different thread (http://codingforums.com/showpost.php...20&postcount=5.) It works, but the more it is used, the faster it runs, can anyone help me diagnose the problem? Code: var colorArr = new Array();
var colorSym = ["0","1","2","3","4","5","6","7","8","9","a","b","c","d","e","f"];
var colorInt;
for (i=0;i<colorSym.length;i++)
{
for (n=0;n<colorSym.length;n++)
{
colorArr.push(colorSym[i]+colorSym[n]);
}
}
function colorTween(celem,r,g,b,time){
initColor = colorToHex(document.getElementById(celem).style.backgroundColor);
origColor = splitColor(initColor);
currColor = splitColor(initColor);
targetColor = [colorArr[r], colorArr[g], colorArr[b]]
colorIncs = [Math.round(diffBetween(origColor[0],targetColor[0])/time),Math.round(diffBetween(origColor[1],targetColor[1])/time),Math.round(diffBetween(origColor[2],targetColor[2])/time)];
startColorFade();
function stopInt() {
if (colorInt) { clearInterval(colorInt); }
}
function startColorFade() {
stopInt();
var colorInt = setInterval("this.colorFader()",time);
}
this.colorFader = function() {
currColor[0] = colorArr[arrayIndex(colorArr,currColor[0]) + colorIncs[0]];
currColor[1] = colorArr[arrayIndex(colorArr,currColor[1]) + colorIncs[1]];
currColor[2] = colorArr[arrayIndex(colorArr,currColor[2]) + colorIncs[2]];
document.getElementById(celem).style.backgroundColor = "#"+currColor.join("");
if (Math.abs(diffBetween(currColor[0],targetColor[0])) <= Math.abs(colorIncs[0])) {
currColor = splitColor("#"+targetColor.join(""));
document.getElementById(celem).style.backgroundColor = "#"+targetColor.join("");
stopInt()
}
}
function arrayIndex(arr,check){
for (var i=0;i<=arr.length;i++)
{
if (arr[i] === check) { return i; }
}
return false;
}
function diffBetween(c1,c2){
var num1 = arrayIndex(colorArr,c1);
var num2 = arrayIndex(colorArr,c2);
return num2-num1;
}
function splitColor(color){
return [color.substring(1,3),color.substring(3,5),color.substring(5,7)];
}
function colorToHex(nhcolor) {
if (nhcolor.substr(0, 1) === '#') {
return nhcolor;
}
var digits = /(.*?)rgb\((\d+), (\d+), (\d+)\)/.exec(nhcolor);
var red = parseInt(digits[2]);
var green = parseInt(digits[3]);
var blue = parseInt(digits[4]);
var rgb = blue | (green << 8) | (red << 16);
return digits[1] + '#' + rgb.toString(16);
}
}
The script can be viewed in action he http://www.webskethio.com/websites/index.php 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 am writing a greasemonkey userscript that simply just takes the underlying width of a td tag, and prints the text in white font over the table so it is viewable to everyone. I wrote the following code Code:
function main()
{
var page = document.getElementById("container");
var td = page.getElementsByTagName("td");
for(i=0; i<td.length; i++)
{
if(td[i].background-color != "")
{
td[i].style.color = "#ffffff";
td[i].innerHTML = td[i].width;
}
}
}
however, When i installed the script.. firefox tells me that "color" is not defined. Is there another way of doing this? Just wanting the width is white font. 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;"> 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 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 |
